Description

Chocolate Peanut Butter Brownies are ultra-rich, fudgy brownies swirled with creamy peanut butter for the perfect sweet and salty combo. These decadent bars are a must for peanut butter and chocolate lovers alike.


Ingredients

Scale
  • 1/2 cup (1 stick) unsalted butter
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder
  • 1/2 cup semisweet chocolate chips (optional)
  • 1/2 cup creamy peanut butter

Instructions

  1. Preheat oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper.
  2. In a microwave-safe bowl, melt the butter. Stir in sugar, eggs, and vanilla until smooth and glossy.
  3. Whisk in cocoa powder, flour, salt, and baking powder until just combined.
  4. Fold in chocolate chips if using.
  5. Pour batter into the prepared pan and spread evenly.
  6. Warm peanut butter slightly in the microwave until pourable, about 15–20 seconds.
  7. Drizzle peanut butter over the brownie batter and swirl with a knife or toothpick for a marbled effect.
  8. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with moist crumbs.
  9. Cool completely before slicing into squares.

Notes

  • Use crunchy peanut butter for added texture.
  • Chill before cutting for clean, sharp edges.
  • Store in an airtight container at room temperature for up to 4 days or freeze for up to 2 months.
