Instructions

In a bowl, combine melted butter and melted chocolate chips. Stir until smooth and glossy.

Add granulated sugar and brown sugar, whisking until fully combined.

Mix in the eggs and vanilla extract until smooth.

Fold in cocoa powder, flour, salt, and baking powder (sift if you want an extra smooth batter). Set aside.

In another bowl, whisk together melted butter and brown sugar until combined.

Add the egg, egg yolk, and vanilla extract. Whisk until smooth.

Mix in flour, baking powder, and salt until just combined.

Fold in chocolate chips.

Line a baking pan with parchment paper.

Scoop half of the brownie batter into the pan in separate sections.

Add all of the blondie batter on top.

Finish by adding the remaining brownie batter in dollops.

Use a knife or toothpick to gently swirl for a marbled effect.

Bake at 350°F for 30–33 minutes, or until the center is just set.

Let the bars cool completely in the pan before slicing for clean cuts.

Slice and enjoy your rich, chewy brownie blondie bars.

Do not overmix the batter. Overmixing will cause the bars to become dense.

Slightly underbake the blondie brownie for a gooey texture.

Use room temperature eggs to help the batter mix more smoothly.
