Instructions:
Prepare the Brownies:
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan.
Prepare the brownie mix according to package instructions and spread into the pan. Bake for 20–25 minutes until a toothpick comes out clean. Let cool completely, then cut into ¾-inch cubes.
Make the Pudding Mixture:
In a large mixing bowl, combine the vanilla pudding mixes, cold milk, peanut butter, and vanilla extract. Whisk for about 2 minutes until thickened. Gently fold in 1½ cups of Cool Whip until fully incorporated.
Assemble the Layers:
In a clear glass trifle dish or large serving bowl, begin with a layer of brownie cubes. Sprinkle half of the mini Reese’s halves on top. Spread one-third of the pudding mixture over the candy layer.
Repeat the Layers:
Add another layer of brownies, the remaining Reese’s pieces, and another third of the pudding mix. Top with the final layer of brownies and remaining pudding mixture.
Finish & Chill:
Spread the remaining Cool Whip evenly over the top. Garnish with additional Reese’s halves if desired. Cover and refrigerate for at least 2 hours before serving to let the flavors meld together.
