Ingredients
Scale
🍫 Brownie Dough:
- ½ cup unsalted butter, room temperature
- ¾ cup light brown sugar
- ¼ cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- ⅓ cup Dutch-process cocoa powder
- 1 cup all-purpose flour
- ¾ tsp baking soda
- ½ tsp salt
- ⅔ cup semi-sweet chocolate chips
🍪 Blondie Cookie Dough:
- 2¾ cups all-purpose flour
- 1 tsp cornstarch
- 1 tsp baking soda
- 1 tsp salt
- 1 cup unsalted butter, browned and cooled
- ¾ cup light brown sugar
- ⅔ cup granulated sugar
- 1 large egg + 1 egg yolk
- 2 tsp vanilla extract
- 1 cup semi-sweet chocolate chips
- Optional: flaky sea salt for finishing
Instructions
- Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
- Make the brownie dough: Cream room-temperature butter with brown and granulated sugars for 3 minutes. Mix in egg and vanilla. In a separate bowl, whisk flour, cocoa powder, baking soda, and salt. Combine with wet ingredients. Stir in chocolate chips.
- Make the blondie dough: Brown the butter in a saucepan, let cool. Beat with brown and white sugars until fluffy. Add egg, yolk, and vanilla. Mix in dry ingredients and fold in chocolate chips.
- Assemble cookies: Roll each dough into equal-sized balls. Press one brownie ball and one blondie ball together and roll to form a single cookie dough ball. Place on prepared baking sheet with at least 2 inches of space between each.
- Bake for 8–10 minutes, until edges are just set. Cool on baking sheet for 5–10 minutes before transferring to a wire rack. Sprinkle with flaky sea salt if desired.
Notes
Chill dough slightly if it’s too soft to roll. You can freeze the shaped cookie balls and bake straight from frozen (add 2–3 mins to bake time).
