ingredient notes
Full ingredient measurements and instructions can be found in the recipe card below!
- 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.
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 ONE: 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. Then stream the hot melted butter into the bowl, constantly whisking until combined.
STEP TWO: 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.
STEP THREE: 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.
STEP FOUR: Layer the brownie batter. Evenly spread the brownie batter on top of the blondie batter.
STEP FIVE: Layer the reserved blondie batter. Using a spoon or cookie scoop, scoop the dough into tablespoon size balls on top of the brownie batter.
STEP SIX: Swirl and bake! Use a skewer or toothpick to swirl the batters together. Don't over-swirl or you will lose the marbled look. 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!
faq's
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.
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.
I have not tested this recipe with gluten-free flour but would love to hear how they turn out!
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!

This is my favorite recipe of yours! I make them at least once a month, especially when there’s a party or birthday to bring them to. Everyone always loves them and they always look so pretty!
Cambrea Gordon says
That's amazing! So happy to hear that, thanks Gemma!

They turned out perfect! So pretty too, they were also highly delicious 😋
Shelbi says
YUM!! If I could give this recipe 100 stars I would! They were the perfect combination of a brownie and a cookie. I brought them to share for a work meeting this week and they were gone in seconds!
Carson says
I saw these on Instagram and immediately put them on my bake list! I've seen a lot of brownie blondie recipes on pinterest and instagram but these are by far the prettiest ones I've seen. They turned out just as instructed. I made sure to read through all the tips and the blog copy and I'm so glad they turned out! Thank you for such an amazing recipe!
Stephanie says
I was skeptical about mixing brownies and blondies together but these were a treat!! So delicious and they turned out just like the photos. I can't wait to make them again everyone loved them!
Mary Lee says
Absolutely wonderful! I thought these tasted like a perfect hybrid of chocolate chip cookie and brownie. The recipe was easy enough to put together, and the finished swirled look feels fancy. I’ll make these again for sure! Definitely do the toothpick test for doneness AND look for golden brownness in the blondie swirls. I initially pulled mine out of the oven at 25 minutes, and they needed more time.
Cambrea Gordon says
Yay! So happy to hear that and thank you so much for sharing them with me on Instagram!! 🙂
Tara says
Will substituting the dark chocolate with milk chocolate compromise the taste? I don’t like dark chocolate but I may not notice the dark when it’s combined with cookie.
Cambrea Gordon says
Hi Tara! It shouldn't make a huge difference, it will likely make them sweeter if anything using milk chocolate. You can always use semi-sweet for an in-between chocolate flavor too!

These were so good. Never had a brownie blondies before. The tops of them had a meringue like snap to it and underneath was perfectly soft and chewy brownie and cookie! I will definitely be making these again.
