Ingredients for Peanut Butter Cup Stuffed Brookies
You’ll need just a handful of ingredients to create these decadent brookies:
Essential Ingredients
- 1 (10 ounce) bag brownie mix plus the oil and egg required by the package directions
- 1 (16 ounce) package refrigerated chocolate chip cookie dough
- 12 Reese’s Peanut Butter Cups bite-sized candies work best
Optional Additions
- Vanilla ice cream for serving alongside warm brookies
How to Prepare the Brownie Batter
Start by getting your brownie base ready:
- Mix the Brownie Base: Follow the package directions for your brownie mix, combining it with the required oil and egg in a medium bowl, stirring until just combined. The batter should be smooth with no lumps remaining, taking about 2 minutes of mixing.
- Prepare the Pans: Line a 12-cup muffin tin with paper liners or grease each cup lightly. Divide the brownie batter evenly among the cups, filling each about halfway up the sides, using roughly 2 tablespoons per cup.
Building the Brookie Layers
Now it’s time to assemble the magic layers:
- Add the Peanut Butter Cup: Press one Reese’s cup into the center of each brownie batter cup, pushing it down so it sits partially submerged but not completely covered.
- Top with Cookie Dough: Tear off pieces of refrigerated cookie dough and flatten them slightly, then place one piece over each peanut butter cup, covering it completely and sealing the edges to the brownie batter below, using about 2 tablespoons of dough per cup.
Baking Your Brookies to Perfection
Follow these baking steps for perfect results:
- Preheat and Bake: Preheat your oven to 350 degrees Fahrenheit. Place the filled muffin tin in the oven and bake for 22 to 26 minutes, until the cookie dough layer is golden brown but still slightly soft in the centers when gently pressed.
- Cool Briefly: Allow the brookies to cool in the muffin tin for 5 minutes before carefully removing them, which allows the chocolate inside to set slightly but keeps them warm for serving.
Variations and Customizations
One of the great things about peanut butter cup stuffed brookies is how adaptable they are to your preferences!
- Different Candy Centers: Swap out Reese’s cups for other candy options like Snickers, Milky Way, or even a small handful of chocolate chips mixed with peanut butter chips for a custom filling.
- Brownie Mix Options: Experiment with dark chocolate or fudge brownie mixes for an even richer chocolate flavor, or try a salted caramel brownie mix for added complexity.
- Cookie Dough Varieties: Use sugar cookie dough instead of chocolate chip if you prefer a less chocolatey overall flavor, or try brown butter cookie dough for a nuttier taste that complements the peanut butter center.
- Topping Additions: Sprinkle sea salt, crushed pretzels, or mini chocolate chips on top of the cookie dough before baking for extra texture and flavor.
