Creating your No Bake Summer Berry Icebox Cake is simple if you follow these easy steps:

1. Prepare the Crust: In a bowl, combine graham cracker crumbs and melted butter. Mix well until all crumbs are coated.
2. Form the Base: Press the mixture firmly into the bottom of a 9-inch square baking dish to form an even layer. Set aside.
3. Make the Cream Mixture: In a large mixing bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until soft peaks form.
4. Add Cream Cheese: In a separate bowl, blend the softened cream cheese until smooth, then gradually fold it into the whipped cream mixture. Mix until combined, being careful not to deflate the whipped cream.
5. Layer the Mixture: Spread a layer of the cream mixture over the prepared crust, smoothing it out evenly.
6. Add Berries: Sprinkle a layer of mixed fresh berries over the cream mixture.
7. Repeat Layers: Repeat steps 5 and 6 until you’ve used all the cream mixture and berries, ending with a final layer of the cream mixture on top.
8. Cover and Chill: Cover the dish with plastic wrap or a lid and refrigerate for at least 4 hours (or overnight) to allow the flavors to meld and the cake to set.
9. Garnish: Before serving, top with additional fresh berries for a beautiful presentation.

This straightforward process makes it easy for anyone to enjoy a delightful dessert without the stress of baking!
