Ingredients

1/2 cup unsalted butter, melted
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/3 cup unsweetened cocoa powder
1/2 cup all-purpose flour
1 teaspoon salt
1 teaspoon baking powder
1/2 cup creamy peanut butter
1/4 cup powdered sugar
1 cup chocolate chips

Instructions

Step 1: Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
Step 2: In a mixing bowl, combine the melted butter and granulated sugar until smooth. Add the vanilla extract and eggs, whisking until fully incorporated.
Step 3: Sift the cocoa powder, all-purpose flour, salt, and baking powder into the wet mixture. Gently mix until just combined, being careful not to overmix.
Step 4: Spread the batter evenly into the muffin cups, filling each about two-thirds full.
Step 5: In a separate bowl, mix the peanut butter with the powdered sugar until smooth. Drop a small spoonful of the peanut butter mixture into the center of each brownie cup and swirl gently with a toothpick.
Step 6: Sprinkle chocolate chips over each cup for an extra chocolatey touch.
Step 7: Bake for 20 to 25 minutes, or until the edges are set and a toothpick inserted near but not in the peanut butter swirl comes out with moist crumbs.
Step 8: Allow the brownie cups to cool in the pan for 10 minutes before transferring them to a wire rack to cool completely.

Tips & Variations

Use almond butter instead of peanut butter for a delicious flavor twist.
Substitute gluten-free flour for all-purpose flour to make this recipe gluten free.
Choose high-quality cocoa powder for a richer chocolate taste.
Lightly warm the peanut butter mixture to make swirling easier.
Add mini marshmallows or chopped nuts to the batter for extra texture and flavor.
Use a piping bag to create precise peanut butter swirls for a professional look.

Storage

Store the brownie cups in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. To reheat, warm gently in the microwave for 10–15 seconds to soften the peanut butter swirl before serving.

How to Serve

The image shows a rich, dark brown chocolate cupcake with a smooth, light brown peanut butter frosting layer on top that drips slightly down the sides. On top of the frosting are several dark chocolate chips, adding texture and contrast. Resting on the cupcake is a cut piece showing multiple layers: a dense, moist chocolate base, topped with a peanut butter layer mixed with chocolate swirls and embedded chocolate chips. The cut piece highlights the creamy texture of the peanut butter mixed with the dense chocolate, giving a marbled effect with dark and light tones. All of this is set on a white marbled surface.

FAQs

Can I use crunchy peanut butter instead of creamy?

Yes, crunchy peanut butter can be used, but it may create a slightly different texture in the swirl. It adds a nice crunch if you enjoy a bit of texture.

How can I tell when the brownies are perfectly baked?

The edges should be set, and a toothpick inserted near but not into the peanut butter swirl should come out with a few moist crumbs. Avoid overbaking to keep the brownies fudgy.
