Introduction

These Peanut Butter Brownie Cups combine rich chocolate and creamy peanut butter in perfect harmony. Easy to make and irresistibly fudgy, they’re perfect for sharing or indulging on your own.

The image shows a close-up of a rich chocolate cupcake with two layers. The bottom layer is a dark, moist chocolate cake with a slightly crumbly texture. On top of this is a thick layer of creamy, light brown peanut butter frosting that slowly drips down the sides. The top layer is another smaller cupcake cut in half, revealing swirls of chocolate and peanut butter inside with visible chocolate chips embedded in the frosting and cake. The cupcake is placed on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1/2 cup melted butter
1 cup granulated sugar
1 teaspoon vanilla extract
2 eggs
1/3 cup cocoa powder
3/4 cup all-purpose flour
1/4 teaspoon baking powder
1/2 cup peanut butter
1/4 cup powdered sugar
Chocolate chips for topping

Instructions

Step 1: In a mixing bowl, combine the melted butter and granulated sugar. Stir until smooth.
Step 2: Add the vanilla extract and eggs to the bowl. Whisk until fully incorporated.
Step 3: Sift in the cocoa powder, all-purpose flour, and baking powder. Mix gently until just combined, being careful not to overmix to keep a light consistency.
Step 4: Spoon the batter into muffin cups, filling each about two-thirds full.
Step 5: In a separate bowl, mix the peanut butter and powdered sugar until smooth.
Step 6: Drop a small amount of the peanut butter mixture into the center of each brownie cup. Use a toothpick to swirl it gently through the batter.
Step 7: Sprinkle chocolate chips over each cup to add extra chocolatey sweetness.
Step 8: Bake for 20 to 25 minutes, or until the edges are set. Insert a toothpick avoiding the peanut butter swirl; it should come out with moist crumbs.
Step 9: Let the brownie cups cool in the pan for about 10 minutes, then transfer them to a wire rack to cool completely.

Tips & Variations

Use high-quality cocoa powder for a deeper chocolate flavor.
Warm the peanut butter mixture slightly to make swirling easier.
Add mini marshmallows or chopped nuts to the batter for extra texture and fun.
For a professional look, use a piping bag to add the peanut butter swirl.
Be careful not to overbake to keep the brownies moist and fudgy.

Storage

Store the brownie cups in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 5 days. Reheat briefly in the microwave to soften the peanut butter and enjoy warm.

FAQs

Can I use crunchy peanut butter instead of smooth?

Yes, crunchy peanut butter will add a bit of texture to the swirl, which some may enjoy. Just be sure to mix it well with the powdered sugar for a smooth consistency.

Can I make these brownies gluten-free?

Absolutely. Substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup, and check that your baking powder is gluten-free.
