Ingredients
Scale
For the Brownie Cookie Dough:
- ½ cup (115g) unsalted butter, softened
- ½ cup (100g) granulated sugar
- ½ cup (100g) brown sugar, packed
- 1 large egg
- 1 tsp vanilla extract
- 1 cup (125g) all-purpose flour
- ⅓ cup (30g) unsweetened cocoa powder
- ½ tsp baking soda
- ¼ tsp salt
For the Peanut Butter Cookie Dough:
- ½ cup (125g) creamy peanut butter
- ¼ cup (60g) unsalted butter, softened
- ½ cup (100g) brown sugar, packed
- ¼ cup (50g) granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 1 cup (125g) all-purpose flour
- ½ tsp baking soda
- ¼ tsp salt
Instructions
- Preheat oven to 175°C (350°F). Line baking sheets with parchment paper.
- Make the brownie dough: In a bowl, beat butter with both sugars until light and creamy. Add egg and vanilla, then mix well. In another bowl, whisk together flour, cocoa powder, baking soda, and salt. Gradually add dry ingredients to the wet mixture. Mix until combined.
- Make the peanut butter dough: In a separate bowl, cream peanut butter, butter, brown sugar, and granulated sugar until smooth. Add egg and vanilla, mixing until incorporated. Combine flour, baking soda, and salt in another bowl, then slowly add to the peanut butter mixture. Stir until dough forms.
- Shape the cookies: Take 1 tbsp of each dough, gently press together, and roll into a ball without overmixing the swirl. Place on baking sheets about 5 cm apart. Slightly flatten tops.
- Bake for 10–12 minutes or until edges are set and centers are slightly soft.
- Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Do not overbake — the centers will continue to firm as they cool.
For more contrast, use dark cocoa powder.
You may add chocolate chips or chopped peanuts for texture.
Store at room temperature in an airtight container for best freshness.
