Directions for Peanut Butter Brownies
Let’s bake this delightful fudgy swirled brownies treat!
Preheat and Prep
- I preheat the oven to 350°F (175°C). I line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal, and lightly grease for this chocolate peanut butter treat.
Mix Brownie Batter
- In a large bowl, I whisk ½ cup melted butter and 1 cup sugar until smooth. I add 2 eggs and 1 tsp vanilla extract, whisking until glossy. I stir in ⅓ cup cocoa powder, ½ cup flour, ¼ tsp baking powder, and ¼ tsp salt until just combined for this cozy recipe, avoiding overmixing.
Prepare Peanut Butter Swirl
- In a small bowl, I mix ⅓ cup peanut butter with 1 tbsp powdered sugar until smooth. I microwave for 10–15 seconds to loosen slightly, ensuring it’s not oily for this fudgy swirled brownies effect.
Assemble and Swirl
- I spread the brownie batter evenly in the prepared pan. I dollop the peanut butter mixture over the batter in small spoonfuls.
- Using a butter knife, I gently drag through the surface to create swirls, keeping them shallow to maintain the marbled look for this chocolate peanut butter treat.
Bake and Cool
- I bake for 20–25 minutes, until a toothpick inserted in the center comes out with moist crumbs.
- I cool in the pan for 30 minutes, then lift out using the parchment and cool completely on a rack. I refrigerate for 30 minutes before cutting for this Peanut Butter Brownies.
