How to Make Peanut Butter Brownie Cups
-
Preheat the oven to 350°F (175°C). This ensures your Peanut Butter Brownie Cups bake evenly and turn out deliciously soft! Grease your mini muffin tin or line it with paper liners for easy cleanup.
-
Prepare the brownie batter. If you're using a box mix, simply follow the package instructions. For homemade, mix melted butter, sugar, eggs, flour, cocoa powder, and salt in a bowl until well combined.
-
Fill each muffin cup about ⅔ full with the brownie batter. This allows space for the peanut butter and keeps the cups from overflowing while baking.

Bake the cups for 12–15 minutes, or until the tops are set. A toothpick should come out with moist crumbs—just right for that fudgy texture you crave!

Press the center of each brownie cup gently right after baking to create a small well. This will hold your creamy peanut butter filling.

Add 1 teaspoon of creamy peanut butter to each well while the brownies are still warm. It will melt slightly, creating a delicious fusion of flavors.
-
Sprinkle semi-sweet chocolate chips over the peanut butter filling while it’s still soft. They’ll melt just enough to create a tempting, fudgy topping.

Cool the brownie cups in the pan for 10–15 minutes. After that, carefully transfer them to a wire rack to cool completely.

Peanut Butter Brownie Cups Recipe FAQs
How do I select the right ripeness for ingredients?
Absolutely! When making Peanut Butter Brownie Cups, the ripeness of the eggs isn’t as crucial, but using fresh eggs ensures better binding. If you’re using melted butter, make sure it’s not too hot to prevent scrambling the eggs when mixed. For peanut butter, a smooth creamy variety works best, though you can certainly use chunky for added texture.
How should I store the Peanut Butter Brownie Cups?
To keep your Peanut Butter Brownie Cups fresh, store them in an airtight container at room temperature for up to 3 days. If you prefer them chilled, they can last in the fridge for about a week. Just make sure to cover them well to maintain their delightful texture and moisture!
Can I freeze these brownie cups?
Very! You can freeze your Peanut Butter Brownie Cups for up to 3 months. To do this, place them in a single layer in a freezer-safe container, with parchment paper in between the layers to prevent them from sticking together. When you’re ready to enjoy them, let them thaw in the refrigerator overnight and reheat in the microwave for about 10-15 seconds for that fresh-baked taste!
What’s a common baking issue with these and how can I fix it?
If your Peanut Butter Brownie Cups are coming out too dry, try checking your baking time! Begin checking around 12 minutes—you're looking for a toothpick that comes out with moist crumbs. If they are too crumbly, this may be due to overmixing the batter. Mix just until combined for that perfect fudgy consistency!
Are there any dietary considerations I should keep in mind?
Absolutely! If you’re making these for someone with allergies, be aware that peanut butter is a common allergen. For a nut-free version, you can substitute the peanut butter with sunbutter (sunflower seed butter). Additionally, for a dairy-free option, use vegan butter and ensure your brownie mix is dairy-free.
Can I modify these cups for different flavors or dietary needs?
The more the merrier! You can easily modify these Peanut Butter Brownie Cups by using different nut butters or even trying a cookie butter for a delightful twist. For a gluten-free version, opt for a gluten-free brownie mix and make sure your chocolate chips are certified gluten-free. Enjoy experimenting with flavors!
