Ingredients

For the Brownie Dough:

✔ ½ cup unsalted butter (melted)
✔ ½ cup granulated sugar
✔ ½ cup brown sugar
✔ 1 large egg
✔ 1 tsp vanilla extract
✔ ⅓ cup unsweetened cocoa powder
✔ 1 cup all-purpose flour
✔ ½ tsp baking soda
✔ ¼ tsp salt

For the Peanut Butter Dough:

✔ ½ cup unsalted butter (softened)
✔ ½ cup peanut butter (creamy or crunchy)
✔ ½ cup brown sugar
✔ ½ cup granulated sugar
✔ 1 large egg
✔ 1 tsp vanilla extract
✔ 1 ¼ cups all-purpose flour
✔ ½ tsp baking soda
✔ ¼ tsp salt

Instructions

1. Make the Brownie Dough

1. In a bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth.
2. Add the egg and vanilla extract, mixing until combined.
3. Stir in the cocoa powder, flour, baking soda, and salt until a soft dough forms.
4. Cover and chill for 15 minutes while preparing the peanut butter dough.

2. Make the Peanut Butter Dough

1. In another bowl, beat softened butter, peanut butter, brown sugar, and granulated sugar until creamy.
2. Add the egg and vanilla extract, mixing well.
3. Stir in flour, baking soda, and salt until a soft dough forms.

3. Shape & Swirl the Cookies

1. Take 1 tablespoon of brownie dough and 1 tablespoon of peanut butter dough and gently press them together.
2. Lightly swirl the two doughs together without fully mixing—this creates the marbled effect.
3. Roll into a ball and place on a parchment-lined baking sheet, spacing them about 2 inches apart.
4. Flatten slightly with your fingers or a fork.

4. Bake & Cool

1. Preheat oven to 350°F (175°C).
2. Bake for 10-12 minutes, until the edges are set but the centers remain soft.
3. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Serving Ideas

🍫 Drizzle melted chocolate over the cookies for an extra indulgent touch.
🥜 Add chopped peanuts for extra crunch.
🍦 Serve warm with a scoop of vanilla ice cream!

Pro Tips
