This Chocolate Peanut Butter Brownie Trifle layers homemade brownies with creamy peanut butter filling and Reese’s Peanut Butter Cups for an easy, crowd-pleasing dessert.
Preheat oven to 350°F. Grease a 9x13-inch baking pan.
In a large bowl, stir together the sugar, cocoa powder, flour, baking powder, and salt until combined.
Add the eggs, water, melted butter, and vanilla extract, stirring until combined. Spread the brownie batter evenly into the prepared pan and bake for 20–24 minutes, or until a toothpick inserted in the center comes out clean. Cool completely.
In a separate large bowl, beat the softened cream cheese and powdered sugar until the mixture is smooth and creamy.
Add the peanut butter and milk, mixing until smooth and combined. Gently fold in the Cool Whip until fully incorporated.
Cut or crumble the cooled brownies into bite-sized pieces. Arrange half of the brownie pieces in the bottom of a trifle dish or large glass bowl.
Spread half of the peanut butter mixture evenly over the brownie layer.
Add the remaining brownie pieces evenly over the peanut butter layer.
Spread the remaining peanut butter mixture evenly over the brownie layer.
Garnish with the chopped Reese’s Peanut Butter Cups. Cover and refrigerate until ready to serve.
Notes
Brownies must be completely cool before assembling the trifle.
Regular creamy peanut butter works best; natural peanut butter may make the filling oily or cause it to separate.
For a shortcut, use a boxed brownie mix prepared according to package directions.
Homemade whipped cream can be substituted for Cool Whip. Whip it until fairly stiff before folding it into the filling.
Keep the trifle covered in the refrigerator until ready to serve.
