Ingredients

Scale
  • 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
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder
  • 1/2 cup creamy peanut butter
  • 1/4 cup unsalted butter, softened
  • 1 cup powdered sugar
  • 23 tablespoons milk or heavy cream
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper or grease it with cooking spray.
  2. In a large bowl, whisk together the melted butter and granulated sugar until smooth. Add the eggs one at a time, followed by the vanilla extract. Whisk until fully combined.
  3. In a separate bowl, sift together the cocoa powder, all-purpose flour, salt, and baking powder.
  4. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
  5. Pour the batter into the prepared pan, spreading it evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with moist crumbs.
  6. Allow the brownies to cool in the pan for at least 30 minutes before frosting.
  7. In a medium bowl, beat the peanut butter and softened butter together until creamy. Gradually add the powdered sugar, mixing on low speed. Add the milk or cream one tablespoon at a time to reach your desired consistency, then mix in the vanilla extract.
  8. Spread the peanut butter frosting evenly over the cooled brownies using an offset spatula or the back of a spoon.
  9. Refrigerate the frosted brownies for 15-20 minutes before slicing for cleaner cuts. Serve and enjoy!

Notes

[‘Don’t overmix the batter to ensure fudgy brownies.’, ‘Use a toothpick to test for doneness; it should come out with moist crumbs.’, ‘Room temperature eggs and butter blend better into the batter and frosting.’, ‘Chill the frosting slightly before spreading for easier application.’, ‘For a smooth frosting finish, use an offset spatula or dip a regular spatula in warm water and wipe it dry before spreading.’]
