Brownie blondies are two delicious desserts in one! They are half brownie and half blondie with a fudgy and gooey texture. This recipe is easy to make with no mixer and simple ingredients that comes out perfect every time!
Preheat the oven to 350 F/180 C and line a square 8x8 baking pan with parchment to line all four sides.
In a large bowl whisk together the light brown sugar, granulated sugar, egg, egg yolk, and vanilla extract until fluffy, about 1 minute.
Stream the melted butter into the bowl while whisking constantly until combined.
Fold in the flour, baking powder, salt, and chopped chocolate until just combined.
Spread all but about ⅔ cup of the batter evenly into the baking pan with an offset spatula. Reserve the 2/3 cup for the top.
In a separate medium bowl, whisk together the sugar, vanilla extract, and egg until fluffy, about 1 minute.
Melt the butter and chocolate chips together until smooth.
Stream the melted butter and chocolate into the bowl, whisking constantly until combined.
Fold in the flour, cocoa powder, chopped chocolate, and salt until just combined.
Evenly spread the brownie batter into the pan.
Use a spoon to dollop the reserved blondie batter on top. Then use a toothpick or skewer to swirl them together.
Sprinkle the extra chopped chocolate on top.
Bake for 25-26 minutes or until a toothpick inserted into the center comes out with just the tip smeared in chocolate.
Let them cool completely on a wire rack before cutting, then enjoy!
