Brownie Blondies

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!

Ingredients

For the Blondie Batter

  • ½ cup + 1 tbsp light brown sugar packed
  • ¼ cup granulated sugar
  • 1 large egg
  • 1 large egg yolk
  • 1 teaspoon vanilla extract
  • ½ cup unsalted butter melted
  • 1 cup + 2 tbsp all-purpose flour
  • ¼ cup chopped dark chocolate
  • ¼ teaspoon baking powder
  • ½ teaspoon salt

For the Brownie Batter

  • ¼ cup + ⅛ cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 4 tablespoon unsalted butter melted
  • cup semi-sweet chocolate chips
  • ¼ cup all-purpose flour
  • ¼ cup unsweetened dark cocoa powder
  • ¼ cup chopped dark chocolate
  • ¼ teaspoon salt
  • cup chopped dark chocolate, for the top

Instructions

Make the Blondie Batter

  • 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 ⅔ cup for the top.

Make the Brownie Batter

  • 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!

recipe notes
  • Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the "metric" button next to the ingredients title on the recipe card.
  • Wait to cut them: I know it can be super hard to wait but it's so worth it! Cutting them too soon will make them fall apart when you try and pick them up.
  • Don't overbake them: The best part of these brownies is the gooey and fudgy texture. To know they are done baking, insert a toothpick into the center. It should come out with the tip smeared with chocolate. If it comes out clean, that's a sign they are overbaked.
  • Baking times may vary: Because all ovens are different, your brownies may take longer or bake quicker than the baking time in the recipe. I recommend checking on them occasionally and checking for doneness!
 
storage & freezing
  • Room temperature: Store the cooled brownies in an airtight container at room temperature for 2-3 days. You can also keep them in the pan and wrap the pan tightly with plastic wrap.
  • Freezer: Cut, then store in an airtight container or freezer bag for up to 1 month!
