Ingredients for Peanut Butter Cup Stuffed Brookies
To create the perfect batch of brookies, you’ll need the following ingredients:
Essential Ingredients
- 1 (10 oz) bag of brownie mix plus oil and egg as specified on the package
- 1 (16 oz) package of refrigerated cookie dough store-bought is perfect for this recipe
- 12 Reese’s Peanut Butter Cups standard size, unwrapped
- Vanilla ice cream optional but highly recommended for serving
Optional Add-ons
- Extra chocolate chips sprinkled on top before baking for additional richness
- Sea salt a light sprinkle to enhance the peanut butter and chocolate flavors
- Crushed peanut butter cups for garnish after baking
How to Prepare the Brownie and Cookie Layers
Here’s how to make these brookies layer by layer:
- Prepare your workspace: Preheat your oven to 350°F and line a standard 12-cup muffin tin with paper liners or lightly grease each cup. This prevents sticking and makes removal easy.
- Make the brownie batter: Follow the package instructions for your brownie mix, combining the mix with the required oil and egg in a mixing bowl. Stir until just combined, about 1 minute, ensuring no lumps remain.
- Layer the base: Divide the brownie batter evenly among the muffin cups, filling each about one-third full. Use a small spoon or cookie scoop to distribute the batter evenly.
- Add the cookie dough: Break off pieces of refrigerated cookie dough and press one piece firmly into the center of each brownie cup, covering most of the brownie batter. The dough will help create the brookie texture.
- Insert the peanut butter cup: Place one unwrapped Reese’s Peanut Butter Cup directly on top of the cookie dough layer in each cup, pressing it down slightly so it nestles into the dough.
Baking the Brookies to Perfection
The baking process is straightforward and requires minimal monitoring:
- Bake: Place the filled muffin tin in the preheated 350°F oven and bake for 20-25 minutes. The brookies are done when the brownie edges are set and the centers still have a slight jiggle when the pan is gently shaken.
- Cool briefly: Remove the tin from the oven and allow the brookies to cool in the pan for 5-10 minutes. This cooling time allows the peanut butter cup to set slightly without becoming too hard.
- Remove from tin: Carefully lift each brookie out of its liner and transfer to a wire rack or serving plate. The warm peanut butter cup center will be slightly melted and gooey, which is exactly what you want.

Variations and Customizations
One of the great things about peanut butter cup stuffed brookies is how easily you can make them your own!
- Different candy centers: Swap Reese’s cups for Snickers, Twix, or any favorite candy piece to create entirely new flavor profiles.
- Brownie mix flavors: Experiment with dark chocolate, fudge, or even mint brownie mixes to change up the base layer.
- Cookie dough variations: Use chocolate chip, sugar cookie, or even brownie-flavored cookie dough for deeper chocolate flavor or vanilla contrast.
- Topping additions: Sprinkle chopped nuts, extra chocolate chips, or crushed candy on top before baking for added texture.

Recipe FAQ’s
Can I use homemade brownie batter instead of a mix?
Absolutely. Use your favorite from-scratch brownie recipe, dividing it among the muffin cups as instructed. The baking time may vary slightly depending on the thickness of your batter, so watch for the edges to set while the centers remain slightly soft.
How should I store leftover brookies?
Store cooled brookies in an airtight container at room temperature for up to 3 days, or refrigerate them for up to 5 days. You can also freeze them for up to 2 months and thaw at room temperature before serving.
What if my peanut butter cups melt completely into the batter?
Some melting is normal and delicious, creating a peanut butter swirl throughout the brookie. If you prefer a more distinct peanut butter cup shape, reduce the baking time by a minute or two or use chilled peanut butter cups straight from the freezer.
