  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 cup light brown sugar, packed
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 cup creamy peanut butter
  • 1/2 cup semi-sweet chocolate chips


Preheat the oven to 350°F (175°C) and line an 8-inch square baking pan with parchment paper.

In a large bowl, whisk together the melted butter and brown sugar until smooth.

Add the egg and vanilla extract and whisk until combined.

In a separate bowl, whisk together the flour, baking powder, and salt.

Add the dry ingredients to the wet ingredients and stir until just combined.

Fold in the peanut butter until fully incorporated.

Pour the batter into the prepared baking pan and smooth the top with a spatula.

Melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring between each interval, until completely melted.

Drizzle the melted chocolate over the top of the batter.

Use a toothpick or knife to create swirls in the batter, dragging the chocolate through the peanut butter mixture.

Bake for 25-30 minutes or until the edges are lightly browned and a toothpick inserted in the center comes out clean.

Let the bars cool completely in the pan before slicing and serving.

These chocolate peanut butter swirl bars are the perfect balance of rich chocolate and creamy peanut butter.
