Ingredients for Peanut Butter Brownies

To make the best peanut butter brownies, you’ll need the following ingredients:

For the Brownie Base:

  • 1 cup (200g) granulated sugar
  • ½ cup (115g) unsalted butter, melted
  • 2 large eggs
  • 1 tsp vanilla extract
  • ⅓ cup (40g) cocoa powder
  • ½ cup (60g) all-purpose flour
  • ¼ tsp salt
  • ¼ tsp baking powder

For the Peanut Butter Swirl:

  • ½ cup (120g) creamy peanut butter
  • 2 tbsp powdered sugar
  • 1 tbsp melted butter
  • 1 tsp vanilla extract

Step-by-Step Instructions

Step 1: Preheat and Prepare the Pan

Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper or lightly grease it.

Step 2: Mix the Brownie Batter

In a large bowl, whisk together melted butter and sugar. Add eggs and vanilla, mixing until smooth. Sift in cocoa powder, flour, salt, and baking powder, then stir until just combined.

Step 3: Prepare the Peanut Butter Swirl

In a separate bowl, combine peanut butter, powdered sugar, melted butter, and vanilla extract until smooth.

Step 4: Layer and Swirl

Pour the brownie batter into the prepared pan. Drop spoonfuls of the peanut butter mixture on top, then use a knife to swirl it into the batter.

Step 5: Bake and Cool

Bake for 25-30 minutes or until a toothpick comes out with moist crumbs. Let the brownies cool completely before slicing.

Expert Tips for Perfect Peanut Butter Brownies

  • Don’t overmix the batter – Overmixing can make brownies dense.
  • Use quality cocoa powder – A dark, rich cocoa enhances the chocolate flavor.
  • Cool before cutting – This prevents crumbling and ensures clean slices.
