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 in the cocoa powder, all-purpose flour, salt, and baking powder. Gently mix until just combined, being careful not to overmix to keep the batter light.
Step 4: Fill each muffin cup about two-thirds full with the brownie batter.
Step 5: In a separate bowl, mix the peanut butter with powdered sugar until smooth. Drop a small amount of this mixture into the center of each brownie cup and use a toothpick to gently swirl it through the batter.
Step 6: Sprinkle chocolate chips on top of each cup to add extra chocolatey sweetness.
Step 7: Bake for 20 to 25 minutes, or until the edges are set and a toothpick inserted into the chocolate (avoiding the peanut butter swirl) comes out with a few moist crumbs.
Step 8: Let the brownie cups cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.

Tips & Variations

Use high-quality cocoa powder for a richer chocolate flavor.
Lightly warm the peanut butter mixture to make swirling easier.
For added texture, try mixing mini marshmallows or chopped nuts into the batter.
Substitute almond butter for peanut butter for a different nutty twist.
Use gluten-free flour instead of all-purpose flour to make this recipe gluten-free.

Storage

Store the peanut butter brownie cups in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. To reheat, warm briefly in the microwave for about 15 seconds to restore softness and gooeyness.

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 for added texture, but keep in mind the swirls might be less smooth.

Can I make these brownie cups ahead of time?

Absolutely. You can prepare and bake them in advance, storing them in an airtight container. They actually taste great the next day once the flavors have melded.
