Ingredients

Scale

Brownie Base

  • 1 cup peanut butter
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 1/2 cup cocoa powder
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 cup chocolate chips

Fudge Frosting

  • 1 cup chocolate chips
  • 1 tablespoon butter
  • 1/2 cup heavy cream

Instructions

  1. Preheat: Preheat your oven to 350°F (175°C) and grease a 9×9 inch baking pan thoroughly to prevent sticking.
  2. Combine Peanut Butter and Sugar: In a mixing bowl, blend the peanut butter and granulated sugar together until the mixture is smooth and well incorporated.
  3. Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully mixed before adding the next. Stir in the vanilla extract to infuse flavor.
  4. Sift Dry Ingredients: In a separate bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt to eliminate lumps and combine evenly.
  5. Mix Batter: Gradually fold the dry ingredients into the peanut butter mixture carefully until just combined to avoid overmixing. Then gently fold in the chocolate chips for texture.
  6. Bake: Pour the batter evenly into the prepared baking pan. Bake in the preheated oven for 20 to 25 minutes until a toothpick inserted near the center comes out with a few moist crumbs.
  7. Make Fudge Frosting: While the brownies bake, melt the chocolate chips and butter together, either over a double boiler or in short intervals in the microwave. Stir in the heavy cream until the frosting is smooth and glossy.
  8. Frost and Set: Once the brownies have cooled completely, spread the fudge frosting evenly on top. Allow the frosting to set before cutting the brownies into 16 squares to serve.

Notes

  • Do not overbake the brownies to maintain their fudgy texture.
  • Use natural peanut butter for best flavor, avoiding varieties with added sugar or oils.
  • Let brownies cool completely before frosting to prevent melting the frosting.
  • Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
  • For a nut-free option, substitute peanut butter with sunflower seed butter.
