why you'll love these brownie blondies
- Brownie batter bottom
- Cookie dough top
- The brownie blondies are made in one bowl
- Hints of coffee in both batters
- These bars have a soft, chewy, and rich flavor!
ingredient notes
- Brown sugar- You can substitute dark brown sugar, but light brown works best for the brownie blondies to be chewy!
- Espresso- Either fresh ground espresso or instant coffee granules work well.
- Cocoa powder- I prefer dark dutch processed cocoa powder for the richest and darkest chocolate flavor.
Full ingredient measurements and instructions can be found in the recipe card below!
helpful equipment & tools
- Kitchen scale: I always recommend weighing your dry ingredients for accurate results when baking.
- Whisk: A standard metal or silicone hand whisk is perfect for making the batters.
- 8x8 nonstick baking pan: This is the exact pan I use for making brownies. It makes your brownie blondies perfectly thick and chewy!
- Mixing bowls: Any medium-sized bowls will work well for making the batters.
- Tooth pick- I use this to swirl the batters together. You could also use a skewer or knife as well.
expert baking tips
- Prep and line your pan first- If the batters sit for too long they will get thicker and are then harder to swirl together.
- Always spoon measure your flour- This means using a spoon to fluff the flour first, then spooning it into your measuring cup. This will give the most accurate results when baking without a kitchen scale.
- Swirl the batters together- Use a toothpick to swirl the batter once in the pan.
- Don't over mix- Don't over mix the batters or the brownie blondies will be tough and dense.
- Don't over bake- Don't over bake the bars or they will be dry and crumbly.
- Wait to cut them- Don't cut the brownie blondies while they're still warm or they will be too gooey and will fall apart.
instructions
step by step
Before you start making the brownie blondies: Prepare your 8x8 nonstick pan with parchment paper and preheat the oven to 350 F/177C. Measure all the ingredients needed for both batters before you start mixing.
Step 1: Make the brownie batter. Whisk together the brown sugar, granulated sugar, espresso, and melted butter in a large bowl.
Step 2: Whisk in the eggs one at a time until combined.
Step 3: Whisk in the flour, cocoa powder, and salt until just combined. Set the bowl aside.
Step 4: Make the blondie batter. Whisk together the brown sugar, espresso, and melted butter in a large bowl. Then whisk in the egg and mix until well combined.
Step 5: Add the flour, salt, and baking powder into the bowl.
Step 6: Whisk until just combined.
Step 7: Use a large scoop to scoop the chocolate batter into the four corners of the pan.
Step 8: Use a different scoop for the cookie and scoop it into the empty spots in between the chocolate batter.
Step 9: Use a toothpick to swirl the two batters together. Bake the brownie blondies for 25-30 minutes until a toothpick inserted into the center comes out with just a few moist crumbs.
NOTE- The brownie blondie batter will get thicker as it sits, which is why it's important to have your pan and all your ingredients ready before you start mixing! If it gets too thick you won't be able to swirl them together.
storage & freezing
- Room temperature: Once cool, wrap brownie blondies tightly in plastic wrap and keep them at room temperature for 2-3 days. Do not refrigerate!
- Freezer: Place the brownies in a sealable container and freeze them for up to one month.
faq's
The middle should be puffy and the color of the top will be a deep golden brown. Stick a toothpick in at an angle into the center and it should have a streak of chocolate on it but not be covered in wet batter.
They are most likely underbaked. Stick the toothpick in at an angle instead of straight up and down to make sure that the batter is baked in the center.
You could definitely use a bigger pan, although I recommend doubling the recipe otherwise the bars will be thin. If you don't double the recipe I recommend checking them at 18 minutes for doneness.

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.
