Peanut Butter Mousse Recipe – Easy, Low-Carb & Creamy Dessert

There’s something undeniably nostalgic about the flavor of peanut butter. For many of us, it brings back memories of childhood lunches, late-night spoonfuls straight from the jar, or cozy kitchen moments spent baking with family. Now imagine taking all that comforting flavor and turning it into a Creamy Peanut Butter Mousse, airy, melt-in-your-mouth kind of dessert that satisfies your sweet tooth without being overpowering or overly rich.

This peanut butter mousse is a dreamy, elegant twist on a classic favorite. With just four simple ingredients, it comes together quickly and easily, making it perfect for both impromptu weeknight treats and impressing guests at dinner parties. It’s naturally sweetened, low in carbs, and entirely free from refined sugar, which means you can indulge without the guilt.

What makes this mousse even better is that it’s incredibly beginner-friendly. You don’t need to be an expert baker or own any fancy kitchen gadgets to make it. A hand mixer and a mixing bowl are all it takes to whip up a dessert that looks and tastes like it came from a restaurant. Plus, it’s completely no-bake, which makes it ideal for warm weather days or times when you just don’t feel like turning on the oven.

I first made this mousse on a whim during a weekend when I was craving something sweet but didn’t want to derail my health goals. I had a tub of heavy cream and a jar of natural peanut butter in the pantry, and within minutes, a new favorite dessert was born. Since then, I’ve made it dozens of times, tweaking and perfecting the balance of flavors until it was just right. Now, it’s my go-to whenever I need something quick, delicious, and a little indulgent.

If you’re ready for a dessert that’s light yet luscious, simple yet impressive, and utterly satisfying in every spoonful, then this peanut butter mousse is calling your name.

Why You’ll Love This Creamy Peanut Butter Mousse Recipe

There are a lot of reasons to fall in love with this mousse, but let’s start with the obvious: flavor. The combination of smooth, natural peanut butter and creamy whipped heavy cream creates a rich, nutty, lightly sweet mousse that’s both comforting and refined. It’s everything you want from a dessert—sweet, creamy, and full of flavor—without any of the heaviness or cloying sweetness found in traditional desserts.

Another reason you’ll adore this recipe is how easy it is to make. There’s no cooking involved, no gelatin to bloom, and no long lists of complicated steps. All you need is a bowl, a mixer, and about ten minutes of your time. It’s the kind of recipe you can make at the last minute when guests are on the way, or whip up on a weeknight just because you deserve a treat.

This recipe is also incredibly versatile. While the base is delightfully simple—just heavy cream, peanut butter, sweetener, and vanilla—you can easily dress it up or down depending on the occasion. Want to add a little crunch? Sprinkle crushed peanuts or sugar-free chocolate chips on top. Looking to impress? Pipe it into individual serving glasses and top with a swirl of whipped cream. Or keep it casual and spoon it into a bowl for a quick and cozy dessert.

And if you’re someone who’s watching your sugar intake or following a low-carb lifestyle, this mousse fits right in. It’s sweetened with powdered erythritol, monk fruit, or allulose, which means it has all the flavor without any of the sugar crash. That makes it a dessert you can feel good about enjoying any day of the week.

Lastly, it’s a total crowd-pleaser. Kids love it, adults can’t get enough of it, and even people who claim not to be dessert lovers usually end up going back for seconds. It’s that good.

Health Benefits of this Creamy Peanut Butter Mousse

While peanut butter mousse might sound like an indulgent treat (and it is), it also offers a few surprising health perks—especially when made with wholesome, low-carb ingredients. First and foremost, peanut butter is a great source of healthy fats and plant-based protein. It helps you feel full and satisfied, which makes it a great option if you’re looking for a dessert that won’t leave you raiding the pantry an hour later.

Natural peanut butter, particularly the unsweetened kind used in this recipe, is also rich in essential nutrients. It contains magnesium, which supports muscle and nerve function, as well as potassium, which helps regulate blood pressure. It’s also packed with antioxidants like vitamin E and resveratrol, which can support heart health and reduce inflammation.

The heavy cream used in the mousse adds a rich texture while contributing calcium, vitamin A, and healthy saturated fats that help with hormone production and nutrient absorption. Because this recipe uses a sugar-free sweetener instead of refined sugar, it avoids the blood sugar spikes and crashes often associated with traditional desserts.

Additionally, this mousse is low in carbohydrates, especially when you choose a low-glycemic sweetener like erythritol or monk fruit. This makes it suitable for people following a keto or low-carb lifestyle, and it’s also diabetic-friendly in moderation.

Because the mousse is so rich and satisfying, you only need a small portion to feel like you’ve truly indulged. This means you’re less likely to overeat, and you can enjoy dessert without compromising your health goals. So, not only does this recipe taste amazing, it also supports a more balanced approach to treating yourself.

Ingredients List of this Creamy Peanut Butter Mousse

Let’s keep things simple and flavorful. Here’s what you’ll need to make the most luscious peanut butter mousse:

Ingredients (Serves 4):

• 1 cup heavy cream: This is the base of the mousse, giving it that rich, silky texture. Make sure to use full-fat heavy whipping cream for best results.
• ½ cup natural, smooth peanut butter: Opt for a version without added sugar or hydrogenated oils. The simpler the ingredients, the better. Natural peanut butter gives the mousse a deep, authentic flavor.
• 2 tablespoons powdered sweetener: You can use erythritol, monk fruit, or allulose. Powdered sweetener blends more easily than granulated, creating a smooth and creamy texture.
• 1 teaspoon vanilla extract: A touch of vanilla rounds out the flavor, adding warmth and depth to the peanut butter.

That’s it! Just four ingredients, all of which you may already have in your kitchen. And even though the list is short, the flavor and texture that come from these ingredients together is nothing short of magic.

Step-By-Step Cooking Instructions of this Creamy Peanut Butter Mousse

Ready to whip up some mousse? Follow these simple steps, and you’ll have a creamy, dreamy dessert in no time.

Step 1: Whip the Cream
Begin by pouring the heavy cream into a mixing bowl. Use a hand mixer or stand mixer with the whisk attachment to whip the cream until soft peaks form. This means the cream should hold its shape but still have a slightly droopy peak when the beaters are lifted.

Tip: Start your mixer on a lower speed to avoid splashing, then gradually increase to medium-high. Keep an eye on the texture—overwhipping can lead to a grainy texture or even butter.

Step 2: Add the Peanut Butter
Once your cream has reached soft peaks, it’s time to add the peanut butter. Scoop it into the bowl and start mixing on low speed to slowly incorporate it. Then gradually increase the speed to medium. The goal is to fully combine the peanut butter with the whipped cream without deflating the mixture.

Tip: If your peanut butter is very thick, you can warm it slightly in the microwave for 10–15 seconds before adding. This helps it blend more easily.

Step 3: Sweeten and Flavor
Add the powdered sweetener and vanilla extract to the bowl. Continue mixing until everything is fully combined and the mixture is smooth, fluffy, and holds its shape well. Taste the mousse and adjust the sweetness if needed—feel free to add another half tablespoon of sweetener if you prefer it a little sweeter.

Step 4: Chill (Optional)
You can enjoy the mousse right away, but chilling it for 30 minutes to an hour allows the flavors to meld and the texture to set even more. Simply cover the bowl with plastic wrap and refrigerate until ready to serve.

Step 5: Serve
When you’re ready to serve, spoon the mousse into individual bowls or glasses. For a fancier presentation, you can pipe it in using a piping bag with a star tip. Garnish with your favorite toppings, such as crushed peanuts, a dollop of whipped cream, or a sprinkle of sugar-free chocolate shavings.

You’ve just made a luxurious dessert in under 15 minutes. How amazing is that?

How to Serve this Creamy Peanut Butter Mousse

Serving this peanut butter mousse can be as simple or as sophisticated as you’d like, which is part of its charm. Whether you’re whipping it up for a quiet night in or presenting it to guests at a dinner party, there are lots of creative and delicious ways to bring it to the table.

For a casual approach, simply spoon the mousse into small dessert bowls or ramekins. The texture is so creamy and the flavor so rich that it really doesn’t need much embellishment to shine. If you want to add a little something extra, top each serving with a dollop of whipped cream and a light dusting of cocoa powder or cinnamon.

To elevate the presentation, use small glass cups, jars, or parfait glasses to showcase the mousse’s luscious, whipped texture. This works especially well if you’re layering it with other ingredients—think chopped roasted peanuts for crunch, or a drizzle of melted sugar-free chocolate for contrast.

Another idea is to serve the mousse as part of a larger dessert platter. Place it alongside fresh berries, low-carb cookies, or even small squares of dark chocolate. The mousse pairs beautifully with all of these, offering a creamy complement to the fruitiness of berries or the richness of chocolate.

For a more playful and interactive option, set up a DIY mousse bar. Provide a few bowls of toppings—crushed nuts, chocolate chips, coconut flakes, or granola—and let everyone customize their own mousse creation. This is always a hit at gatherings and allows each guest to tailor their dessert to their taste.

No matter how you serve it, this peanut butter mousse is sure to be the highlight of the dessert table. It’s light yet satisfying, elegant yet comforting, and it plays well with both bold and subtle flavors.

Pairing Suggestions

Peanut butter mousse is delightful on its own, but pairing it with the right foods and beverages can elevate the entire experience. Because it’s rich, creamy, and mildly sweet, it goes well with a variety of textures and flavors. Whether you’re serving it as the grand finale of a dinner or as part of a dessert spread, here are some pairing ideas to inspire you.

First, consider pairing it with something fruity. The natural sweetness and acidity of fruits like raspberries, strawberries, or even slices of banana contrast beautifully with the nutty richness of the mousse. Try serving it with a fresh berry salad or a spoonful of homemade raspberry compote for a vibrant, refreshing contrast.

Next, think about texture. A little crunch goes a long way in balancing the mousse’s soft, airy feel. You can serve it with a side of crisp almond cookies, sugar-free biscotti, or homemade granola. Even just a sprinkle of crushed roasted peanuts or cacao nibs on top adds a satisfying bite.

If you’re planning a dessert course and want a more decadent presentation, peanut butter mousse pairs beautifully with a small square of flourless chocolate cake or a piece of keto brownie. The deep chocolate flavor enhances the peanut butter and creates that classic combo everyone loves.

For a lighter pairing, consider a crisp cucumber and mint salad as a prelude to dessert. The refreshing, palate-cleansing nature of the salad makes the mousse feel even more indulgent when it’s served.

In terms of beverages, non-alcoholic pairings like unsweetened iced green tea, a warm herbal infusion, or even a frothy decaf cappuccino complement the mousse without overpowering it. A glass of cold almond milk is another great option, especially for kids.

And if you’re enjoying this mousse as a mid-day treat, pair it with a protein-packed smoothie or a high-fiber cracker to make it part of a balanced mini-meal.

Storage, Freezing & Reheating Instructions

If you’ve made a batch of this mousse and have leftovers—or if you’re prepping ahead for a special occasion—you’ll be happy to know that this dessert stores beautifully. It keeps its texture well in the fridge, and you can even freeze it for later enjoyment.

How to Store in the Fridge

Transfer the mousse into an airtight container or individual jars with lids. Store it in the refrigerator for up to 3 days. While the flavor will remain the same, the texture may thicken slightly after a day or two. If it firms up more than you like, just give it a quick stir before serving.

Can You Freeze Peanut Butter Mousse?

Absolutely. To freeze, spoon the mousse into freezer-safe containers, leaving a little room at the top for expansion. You can also freeze it in individual portions using silicone muffin molds or small ramekins. Once solid, cover with a tight-fitting lid or plastic wrap and freeze for up to 1 month.

When you’re ready to enjoy, transfer the mousse to the refrigerator and allow it to thaw for a few hours or overnight. Do not microwave to defrost, as it can affect the texture.

Interestingly, some people actually enjoy eating the mousse semi-frozen—it takes on the texture of ice cream and can be a fun, refreshing summer treat.

Reheating (If Needed)

Because this dessert is meant to be served chilled or at room temperature, there’s no need for reheating. If it’s too cold straight from the fridge, simply let it sit out for about 10 minutes to soften slightly before serving.

Following these simple storage tips will ensure that your peanut butter mousse stays delicious, whether you’re enjoying it right away or saving some for later.

Common Mistakes to Avoid

Even with a recipe as simple as this, there are a few common pitfalls that can impact the final result. Here are the top mistakes to watch out for—and how to avoid them—so your mousse turns out perfect every time.

1. Overwhipping the Cream
It’s easy to get carried away with the mixer, but whipping the cream too long can cause it to turn grainy or even separate. Stop as soon as soft peaks form, and be especially careful once you add the other ingredients.

2. Using Chunky Peanut Butter
While chunky peanut butter is great for sandwiches, it’s not ideal for mousse. The chunks can disrupt the smooth, airy texture. Always use smooth, natural peanut butter for best results.

3. Not Using Powdered Sweetener
Granulated sweeteners can give the mousse a gritty texture, which isn’t very pleasant. Stick with powdered forms of erythritol, monk fruit, or allulose to keep the texture silky smooth.

4. Adding Ingredients Too Quickly
When you’re mixing in the peanut butter and sweetener, do it gradually and at a lower speed. Dumping everything in at once can deflate the whipped cream or create a lumpy mixture.

5. Not Tasting as You Go
Everyone’s sweetness preference is a little different. Always taste your mousse before chilling and adjust the sweetener if needed. Once it’s cold, it can be harder to remix.

6. Using Low-Fat Cream or Milk
Heavy cream is key here. Using milk or low-fat alternatives won’t whip properly and won’t give you the thick, luxurious texture that makes mousse so satisfying.

Avoiding these common issues ensures that every batch of mousse is as delicious and delightful as it should be.

Pro Tips

Want to take your peanut butter mousse game to the next level? Here are some expert tips and tricks to help you master this recipe every time.

1. Chill the Bowl and Beaters
Before whipping the cream, place your mixing bowl and beaters in the fridge or freezer for about 10–15 minutes. Cold equipment helps the cream whip faster and more evenly.

2. Choose the Right Peanut Butter
Go for a high-quality, natural peanut butter made with just peanuts and salt. Stir it well to make sure it’s evenly mixed before using. Avoid peanut butters with added sugar or oils, which can throw off the texture and flavor.

3. Pipe for a Professional Finish
If you’re serving guests or want to impress, transfer the mousse to a piping bag and pipe it into glasses. It looks stunning and gives the mousse a light, cloud-like appearance.

4. Add a Flavor Boost
Want to mix things up? Add a pinch of sea salt, a touch of cinnamon, or even a few drops of peanut butter extract to intensify the flavor. A teaspoon of cocoa powder can also add depth and a chocolatey twist.

5. Make It a Parfait
Layer the mousse with crushed keto cookies or fresh berries to create a beautiful, layered dessert. This works especially well in clear glasses where the layers are visible.

6. Use Leftovers Creatively
Leftover mousse can be used as a frosting for cupcakes, a filling for crepes, or even spread between two almond flour cookies for a dessert sandwich.

These little details might seem small, but they can elevate your dessert from great to unforgettable.

Frequently Asked Questions (FAQs)

1. Can I use store-bought peanut butter for this recipe?
Yes, you can use store-bought peanut butter, but make sure to choose a smooth and natural variety with no added sugar or hydrogenated oils. The best peanut butters for this recipe are those with just peanuts and maybe a pinch of salt. Avoid ones labeled as “creamy” if they contain stabilizers or extra sweeteners, as they can affect both flavor and texture.

2. What type of sweetener works best?
Powdered erythritol, monk fruit, or allulose are ideal. They blend easily without any grittiness. Powdered sweetener is important for achieving a smooth mousse. If all you have is granulated, you can blitz it in a blender or food processor to make your own powdered version.

3. Can I make this ahead of time?
Absolutely! In fact, this mousse benefits from a bit of chill time. You can prepare it up to 24 hours in advance and store it in the refrigerator. Just keep it covered to prevent it from absorbing other fridge odors, and give it a gentle stir before serving if it thickens too much.

4. Can I freeze this Peanut Butter Mousse?
Yes, the mousse freezes well. Freeze in individual portions and thaw in the fridge before serving. It also tastes amazing when slightly frozen—it’s like a no-churn peanut butter ice cream.

5. Is this mousse keto-friendly?
Definitely. It’s low in net carbs, high in healthy fats, and sugar-free. Just be sure your peanut butter and sweetener are keto-approved.

6. Can I use almond butter instead of peanut butter?
Yes, almond butter works beautifully as a substitute. It has a milder flavor but pairs well with the cream and sweetener. Cashew butter is another great alternative if you’re looking for a slightly sweeter, creamier result.

7. How long will the Peanut Butter Mousse last in the fridge?
Stored in an airtight container, the mousse will keep for up to 3 days. After that, the texture might begin to change as the cream naturally starts to break down, but it will still be safe to eat.

8. What if I don’t have a hand mixer?
You can whip the cream by hand using a whisk—it just takes more effort and time. Chill your bowl and whisk beforehand to make the process easier. You’ll get a great arm workout and a delicious reward at the end.

9. Can I add chocolate to thisPeanut Butter Mousse?
Absolutely. A tablespoon of unsweetened cocoa powder or a swirl of melted sugar-free chocolate adds a rich chocolate-peanut butter flavor. You can even fold in chocolate chips or cacao nibs for a little crunch.

10. How can I make this dairy-free?
To make a dairy-free version, try using canned coconut cream in place of the heavy cream. Chill the can overnight, scoop out the solid cream, and whip it just like you would regular cream. Make sure your peanut butter and sweetener are also dairy-free and compatible with your dietary needs.

These common questions cover the bases for making this mousse your own while ensuring it stays foolproof and fun to prepare.
