Ingredients
Brownie Base
- 1 stick unsalted butter
- 1 cup granulated sugar
- 2 large eggs room temperature
- 1 tsp vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 tsp salt
- 1/4 tsp baking powder
Peanut Butter Swirl
- 1/3 cup creamy peanut butter
- 2 tbsp powdered sugar
- 1 tbsp milk
Instructions
- Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving overhang on two sides.
- In a medium microwave-safe bowl, melt the butter in 30-second intervals. Stir in the sugar until combined.
- Add eggs one at a time, whisking well after each addition. Stir in vanilla.
- Add cocoa powder, flour, salt, and baking powder. Stir until just combined — do not overmix.
- In a small bowl, stir together peanut butter, powdered sugar, and milk until smooth and pourable.
- Pour brownie batter into the prepared pan and spread evenly.
- Drop spoonfuls of peanut butter mixture over the top of the batter. Use a toothpick or butter knife to swirl it through in a figure-eight pattern.
- Bake for 28–30 minutes, until the edges are set and the center has a slight jiggle.
- Cool in the pan for at least 25–30 minutes before lifting out and slicing into 16 squares.
Notes
Store in an airtight container at room temperature for up to 4 days, or refrigerate for up to a week. These also freeze beautifully — wrap individual squares and freeze for up to 2 months.
