How to Make Peanut Butter Cup Stuffed Brookies
-
Preheat your oven to 350°F (175°C) and grease a standard muffin tin generously to ensure easy removal of the brookies later.
-
Prepare the brownie mix according to the package directions, stirring until smooth, and set aside while you work on the cookie layer.
-
Form the refrigerated cookie dough into 12 equal balls and flatten them into the bottom of each muffin cup, creating a nice base for your brookies.
-
Place one Reese’s Peanut Butter Cup upside-down on top of the pressed cookie dough to let that creamy center shine through.
-
Distribute the prepared brownie batter evenly over the peanut butter cups until the muffin cups are filled about 90%. Avoid overfilling to allow for rising.
-
Bake for 18-20 minutes or until the brownie batter looks cooked through—insert a toothpick to check, and you want a few moist crumbs sticking to it.
-
Cool for about 5 minutes in the pan, then carefully remove the brookies to a wire rack to finish cooling. Serve them warm with optional vanilla ice cream for an indulgent treat!
Optional: Top with a drizzle of chocolate sauce for extra sweetness.

Peanut Butter Cup Stuffed Brookies Recipe FAQs
How do I choose the best brownie mix for my Peanut Butter Cup Stuffed Brookies?
Absolutely! Go for a quality brownie mix with rich, chocolate flavor. You can choose between regular, low-sugar, or even gluten-free options if needed. Personally, I often grab my favorite brand for a gooey and fudgy texture that pairs beautifully with the cookie layer.
How should I store leftover Peanut Butter Cup Stuffed Brookies?
Very easy! Simply place your brookies in an airtight container at room temperature for up to 3 days. If you want to keep them longer, refrigerate them for up to a week. Just let them come to room temperature before enjoying again!
Can I freeze Peanut Butter Cup Stuffed Brookies?
Absolutely! To freeze, arrange the brookies in a single layer on a baking sheet and place that in the freezer for about 1-2 hours until they’re solid. Then transfer them into an airtight container or a freezer-safe bag. They can last up to 3 months frozen. When you’re ready to eat, just thaw in the fridge overnight or microwave for 30 seconds until warm.
What should I do if my brookies are sticking to the muffin tin?
A common issue! Make sure you’re greasing the muffin tin generously to prevent sticking. If you find them stuck despite this, try using a silicone spatula to gently coax them out after letting them cool for about 5 minutes. If you still have trouble, consider trying muffin liners next time for easy removal!
Are there any dietary considerations I should be aware of?
Definitely! If anyone has allergies, keep in mind that peanut butter cups contain peanuts and other potential allergens. For a nut-free alternative, you can use caramel candies or allergen-free chocolate candies. Feel free to adjust the brownie and cookie dough mixes to fit dietary needs—many brands offer gluten-free and lower-sugar options!
Can I add any extra ingredients to my brookies?
Very much so! You can customize them by mixing in chocolate chips, nuts, or even adding a layer of caramel sauce within the brookie. Just be careful not to overcrowd the mix with too many extras, as they still need to bake evenly. Keeping it simple often yields the most delightful results!
