Ingredients
Method
- Prepare the Butter Cookie Dough:
- In a large bowl, cream the softened butter, granulated sugar, and powdered sugar until light and fluffy.
- Add the egg and vanilla extract and mix until smooth.
- In a separate bowl, whisk together the flour, baking powder, and salt.
- Gradually add the dry ingredients to the wet mixture, mixing until the dough comes together.
- Cover and refrigerate the dough for 30 minutes.
- Prepare the Brownie Dough:
- In a separate bowl, melt the butter and whisk together with sugar, egg, and vanilla extract until smooth.
- Stir in the cocoa powder, salt, flour, and baking powder until combined. The dough should be thick and fudgy.
- Form the Swirls:
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Scoop tablespoon-sized portions of both the butter cookie dough and brownie dough.
- Place the dough balls on the baking sheet and use a toothpick or skewer to swirl the two doughs together, creating a marbled effect.
- Bake:
- Bake the cookies for 10–12 minutes, or until the edges are golden and the centers are set.
- Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
Notes
Make sure to chill the dough before baking to ensure the cookies hold their shape.
If you prefer a more intense chocolate flavor, add some chocolate chips or chopped chocolate to the brownie dough.
These cookies are best enjoyed the day they are made, but they can be stored in an airtight container for up to 3 days.
