📋 Instructions:

1️⃣ Prepare the Brownie Layer:

1. Preheat & Prepare: Preheat your oven according to the instructions on the brownie mix box. Grease a 9-inch springform pan and line the bottom with parchment paper for easy removal.
2. Bake Brownie: Prepare the brownie batter as directed on the box. Pour the batter into the prepared pan and bake according to the package instructions. Once baked, allow the brownie to cool completely.
3. Set the Base: Once cooled, place the brownie back into the springform pan. Line the sides of the pan with parchment paper, allowing it to extend a few inches above the pan’s edge. Evenly distribute the mini Reese’s on top of the brownie layer. Set aside.

2️⃣ Make the Peanut Butter Mousse:

1. Bloom Gelatin: In a small bowl, sprinkle gelatin over water and let it sit for about 5 minutes.
2. Heat Cream: In a microwave-safe bowl, microwave 3/4 cup of heavy cream until it reaches a full boil.
3. Combine: Add the gelatin mixture to the hot cream and whisk until the gelatin is fully dissolved. Pour the mixture over the peanut butter chips and let it sit for a minute before whisking
