This is an easy dessert to whip up after dinner or for a special after-school treat. The way they make the kitchen smell while they’re baking is magical!

Ingredients:
- Box of brownies
- Reese’s Peanut Butter Cups
- Tube of refrigerated cookie dough
You can use traditional brownies, but we highly suggest using the Supreme Triple Chunk brownie mix. What makes it better? It has chocolate chunks, which just adds extra deliciousness to the Brookies. The combination of chocolate, peanut butter, and cookie dough is heavenly!

Instructions:
Using a knife, cut the roll of cookie dough into 12 pieces. A simple steak knife cuts through the plastic very easily. The dough falls away from the plastic making this step as simple as can be! Now it’s time to fill a cupcake pan with paper liners. Press the 12 cookie dough pieces into the bottom of each cup.

Now it’s time to unwrap the Reese’s Peanut Butter Cups! This is a job that kids are great at:) Today, the weather is very warm here in Orange County, so the chocolate was already starting to melt a little bit. Place the Reese’s Cups upside down over the cookie dough.

Next, prepare the brownie batter according to the directions on the box. Spoon the batter over the Reese’s Cups until the liners are almost full. They will rise a little bit as they bake, but not as much as a muffin. So, leaving a little extra space is all you need!

Bake the Peanut Butter Cup Brookies at 350 degrees for about 20 minutes. The center of each Brookie cup will dip down a little bit, but that’s normal because of the candy. You may have leftover brownie batter that you can bake in a small pan separately.

By this time, you will have some people in the kitchen waiting to eat them because the whole house smells so good. You can eat them with ice cream, whipped cream, or alone straight out of the cupcake liner. If you have leftovers, store them in a container or baggie at room temperature. They can be warmed up in the microwave or enjoyed at room temp.
