    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!

    This twist of two desserts into one means you'll never have to choose again!

    I used half of the base of my espresso brownies and chocolate chip blondies to make these brownie blondies!

    They have a mix of caramel and chocolate flavor, are super gooey, and fudgy, and have pools of chocolate in every single bite!

    They are so easy to make, and even though you have to make two batters, they come together quickly and no mixer is required.

    If you love brownies, try my super popular Birthday Sprinkle Brownies, S'mores Brownie Bars, and Pecan Pie Brownies!

    why you'll love this recipe

    • Best of both worlds: Can't choose between making brownies or blondies? With this recipe, you don't have to decide! They are the best of both worlds and are guaranteed to satisfy any chocolate or cookie craving.
    • Easy recipe: Both batters come together with almost the same simple ingredients. You don't even need a stand mixer to make them, just like my miso brownies!
    • Fudgy: If you are a fudgy brownie lover, you are going to love every gooey bite of these bars.

    ingredient notes & substitutions

    ingredients needed to make brownie blondies in bowls.

    Cocoa powder: This recipe is best with dark unsweetened cocoa powder for the richest flavor. You can substitute it for regular cocoa powder as well!

    Brown sugar: I prefer light brown sugar for this recipe to give more distinction between the blondie and brownie batter but you can also use dark brown sugar.

    Egg: You will need whole eggs and extra egg yolk. The extra yolk is what makes them extra chewy!

    Chocolate chips: This recipe is best with semi-sweet or dark chocolate chips. I recommend a high-quality brand like Ghiradelli or Guittard for the best flavor.

    Chopped chocolate bar: I love how the chopped chocolate looks in these bars but you can also use regular chocolate chips instead.

    Full ingredient measurements and instructions can be found in the recipe card below!

    recipe instructions

    Here's how to make these brownie blondies! You do not need a stand mixer to make them but you will need two mixing bowls and a whisk. Before you start, line a square 8x8 baking pan with parchment paper and preheat the oven to 350 F/180 C.

    STEP 1: Make the blondie batter. In a medium bowl, whisk together the light brown sugar, granulated sugar, egg, egg yolk, and vanilla extract until light and fluffy (image 1 below).

    Then stream the hot melted butter into the bowl, constantly whisking until combined.

    STEP 2: Mix in the dry ingredients. Fold the all-purpose flour, baking powder, salt, and chopped chocolate into the batter with a rubber spatula until just combined.

    Evenly spread all but about â…” cup of the batter into the prepared baking pan. Set the pan and the reserved blondie batter aside (image 2 below).

    STEP 3: Make the brownie batter. Whisk together the granulated sugar, egg, and vanilla extract in a separate small bowl until light and fluffy.

    Melt together the chocolate chips and butter, stirring until melted and smooth. Once smooth, stream it into the batter bowl, whisking constantly until just combined.

    Then fold in the all-purpose flour, cocoa powder, salt, and chopped chocolate until just combined (image 3 above).

    STEP 4: Layer the brownie batter. Evenly spread the brownie batter on top of the blondie batter (image 4 above).

    STEP 5: Layer the reserved blondie batter. Using a spoon or cookie scoop, scoop the dough into tablespoon size balls on top of the brownie batter (image 5 above).

    STEP 6: Swirl and bake! Use a skewer or toothpick to swirl the batters together. Don't over-swirl or you will lose the marbled look (image 6 below).

    Sprinkle the top with more chopped chocolate. Then bake for about 25 minutes or until a toothpick inserted into the center comes out with the tip smeared in chocolate.

    expert baking tips

    • 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!

    recipe faqs

    How do I know brownie blondies are done baking?

    You will know when the top of the blondie batter looks golden brown and shiny. Stick a toothpick into the center and pull it out. If the tip is smeared with chocolate, they are done! They will continue to bake even out of the oven.

    Can I make this recipe in a 9x13 pan?

    Definitely! I recommend making a double batch otherwise they will be way too thin. They will also take longer to bake so start checking them at around 30 minutes.

    Can I use gluten-free flour?

    I have not tested this recipe with gluten-free flour but would love to hear how they turn out!

    Why did my brownie blondies sink in the middle?

    If the middle sinks while cooling it's likely they are underbaked. If a toothpick inserted comes out covered in thick batter, they need more time to bake!
