Creating Drinkable Pumpkin Pie is simple when you follow these easy steps:

1. Combine Ingredients: In a medium saucepan, combine the pumpkin puree, milk, heavy cream, and brown sugar.
2. Add Spices: Stir in the vanilla extract, pumpkin pie spice, cinnamon, and nutmeg until fully mixed.
3. Heat Mixture: Set the saucepan over medium heat and cook, stirring frequently until the mixture is hot but not boiling.
4. Blend for Smoothness: Use an immersion blender to puree the mixture until smooth and creamy. If you don’t have an immersion blender, carefully transfer the mixture to a regular blender and blend until smooth, then return to the saucepan.
5. Taste and Adjust: Taste the mixture and adjust the sugar or spices as desired for your preferred flavor.
6. Heat Again: Return the saucepan to low heat for a few more minutes to ensure everything is well-heated.
7. Serve Hot: Pour the drink into mugs or glasses and top with whipped cream if desired.
8. Garnish: Sprinkle ground cinnamon on top for an added touch of flavor and presentation.

Following these straightforward steps will lead you to the delicious creation of Drinkable Pumpkin Pie!
