Equipment

  • 8 × 8-inch square baking pan
  • Parchment paper
  • Silicone spatula

Ingredients
  

  • ½ cup 1 stick unsalted butter, melted
  • 1 cup packed light brown sugar
  • 1 large egg plus 1 large egg yolk at room temperature
  • 1 tablespoon vanilla extract
  • 1 cup all-purpose flour
  • ¼ teaspoon baking powder
  • ½ teaspoon salt
  • ¼ cup creamy peanut butter such as Jif, Skippy, or Peter Pan – not natural peanut butter
  • ¼ cup fruit jam or preserves of your choice

Instructions
 

Prepare the Pan:

  • Preheat your oven to 350°F.
  • Line an 8 × 8-inch square baking pan with parchment paper, ensuring it covers all sides for easy removal.

Mix Wet Ingredients:

  • In a large mixing bowl, combine the melted butter and light brown sugar.
  • Add the whole egg, extra yolk, and vanilla extract, whisking until smooth and well-blended.

Combine Dry Ingredients:

  • Gradually add the flour, baking powder, and salt to the wet mixture.
  • Gently fold with a silicone spatula until just combined, avoiding overmixing.

Add Swirls:

  • Pour the batter into the prepared pan, spreading it evenly.
  • Drop 6 to 8 spoonfuls each of peanut butter and jam over the top of the batter.
  • Use a butter knife to create swirls by gently dragging through the peanut butter and jam.

Bake:

  • Place the pan in the preheated oven.
  • Bake for 25-30 minutes, or until the edges are set, the top is golden, and a knife inserted into the center (avoiding the swirls) comes out clean.

Cool and Serve:

  • Let the blondies cool completely in the pan on a wire rack.
  • Lift them out using the parchment paper.
  • Cut into 9 squares for larger blondies or 18 triangles for smaller portions.

Notes

  • For best results, avoid using natural peanut butter, as it may not blend smoothly.
  • You can switch the jam flavor based on your preference (strawberry, raspberry, grape, etc.).
  • Ensure your eggs are at room temperature for a smoother batter.
