Ingredients
- 1/2 cup unsalted butter
- 8 oz semisweet or dark chocolate, chopped
- 3/4 cup granulated sugar
- 1/4 cup packed brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour
- 1/4 cup unsweetened cocoa powder
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup creamy peanut butter (for swirling)
Instructions
- Step 1: Melt Butter and Chocolate
- In a heatproof bowl, melt the butter and chopped chocolate together, either using a microwave in 30-second intervals or a double boiler. Stir until smooth and set aside to cool slightly.
- Step 2: Whisk Eggs and Sugars
- In a large mixing bowl, whisk together the granulated sugar, brown sugar, eggs, and vanilla extract. Beat for 2–3 minutes until the mixture is pale and thickened—this helps create that signature brownie crust.
- Step 3: Mix Wet and Dry Ingredients
- In another bowl, whisk together the flour, cocoa powder, baking powder, and salt. Slowly stir the melted chocolate mixture into the egg mixture, then fold in the dry ingredients just until combined.
- Step 4: Scoop and Swirl
- Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper. Scoop the dough into 1.5 tablespoon-sized mounds. Use the back of a spoon to make a small indent on top of each cookie and swirl in about 1 teaspoon of peanut butter.
- Step 5: Bake
- Bake for 10–12 minutes. The edges should be set, and the tops crackly, but the centers still soft. Let cool on the tray for 5 minutes before transferring to a wire rack.
Notes
These cookies are best enjoyed slightly warm with a glass of milk. You can reheat them in the microwave for 10–15 seconds to bring back their gooey texture.

HOW TO MAKE PEANUT BUTTER BROWNIE COOKIES:
These cookies come together in under an hour and bring all the joy of brownies and cookies rolled into one chewy, rich dessert.
STEP-BY-STEP INSTRUCTIONS:
Step 1: Melt Butter and Chocolate
In a heatproof bowl, melt the butter and chopped chocolate together, either using a microwave in 30-second intervals or a double boiler. Stir until smooth and set aside to cool slightly.
Step 2: Whisk Eggs and Sugars
In a large mixing bowl, whisk together the granulated sugar, brown sugar, eggs, and vanilla extract. Beat for 2–3 minutes until the mixture is pale and thickened—this helps create that signature brownie crust.
Step 3: Mix Wet and Dry Ingredients
In another bowl, whisk together the flour, cocoa powder, baking powder, and salt. Slowly stir the melted chocolate mixture into the egg mixture, then fold in the dry ingredients just until combined.
Step 4: Scoop and Swirl
Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper. Scoop the dough into 1.5 tablespoon-sized mounds. Use the back of a spoon to make a small indent on top of each cookie and swirl in about 1 teaspoon of peanut butter.
Step 5: Bake
Bake for 10–12 minutes. The edges should be set, and the tops crackly, but the centers still soft. Let cool on the tray for 5 minutes before transferring to a wire rack.
HELPFUL TIPS:
- Don’t overbake—the center should look slightly underdone when you remove them.
- Use creamy peanut butter for the best swirl (natural peanut butter can be too runny).
- For a nut-free version, try using sunflower seed butter.
- Want an extra chocolate hit? Fold in chocolate chips or chunks to the dough.
- For perfectly round cookies, use a spoon to nudge the edges into shape right after baking.

Can I use boxed brownie mix for this?
This recipe is from scratch to get that perfect texture, but if you’re short on time, you can experiment by adding flour and baking powder to a boxed mix to form a dough.
Do I need to chill the dough?
No chilling needed! The dough is ready to scoop and bake immediately.
Can I freeze the cookie dough?
Yes. Scoop the dough onto a tray, freeze until solid, then transfer to a freezer bag. Bake straight from frozen, adding 1–2 extra minutes.
