Instructions
Prepare the Brownies:
- Bake the Brownies: Prepare the brownie mix according to package instructions (or your homemade recipe) in a 9×13-inch pan. Let them cool completely, then cut into small squares.
Make the Peanut Butter Mousse:
- Combine Peanut Butter and Cream Cheese: In a large bowl, beat together the peanut butter and softened cream cheese until smooth.
- Add Sugar and Vanilla: Gradually add the powdered sugar and vanilla extract, continuing to beat until well incorporated.
- Fold in Whipped Cream: Gently fold the whipped cream into the peanut butter mixture until no white streaks remain, creating a light and fluffy mousse.
Assemble the Trifle:
- Layer Brownies: In a large trifle dish or glass bowl, place a layer of brownie squares at the bottom.
- Add Peanut Butter Mousse: Spread a layer of peanut butter mousse over the brownies.
- Add Whipped Topping: Add a layer of whipped topping over the mousse.
- Repeat Layers: Continue layering brownies, peanut butter mousse, and whipped topping until the dish is filled, ending with a layer of whipped topping.
- Garnish: Sprinkle the top with chopped peanuts or chopped peanut butter cups for garnish.
Chill and Serve:
- Refrigerate the Trifle: Cover and refrigerate the trifle for at least 2 hours to allow the flavors to meld and the dessert to set.
- Serving: Serve chilled, spooning out portions that include all the layers.
