Preheat oven to 350 degrees F. Lightly coat a 9x13 pan with cooking spray.
Prepare a 19.5-oz. box of chocolate fudge brownie mix according to package directions. Spread the batter in the pan and set aside.
In a large bowl, beat one 8-ounce package of softened cream cheese with a hand-held mixer until fluffy.
One 14-ounce can sweetened condensed milk
1/2 cup creamy peanut butter
Beat until smooth.
Stir in a 12-ounce package of Reese's Pieces candies.
Spoon the mixture over the brownie batter and spread evenly.
Bake for 40 minutes or until the cheesecake layer is set and the edges are golden brown. Cool for 30 minutes and refrigerate for 30 minutes.
Add the following ingredients to a small microwaveable bowl:
One 12-ounce bag milk chocolate chips
3 tablespoons whipping cream
Microwave on high for 1 minute, or until the chips are melted. Stir until smooth. Spread over the cheesecake layer. Sprinkle 12 large Reese's Peanut Butter Cups (chopped) over the top. Store covered in the refrigerator.
