Half-and-Half Chocolate Chip Cookies

Gooey chocolate chip cookie dough and double chocolate cookie dough baked together. Two flavors in one cookie, and they're just as easy as making one batch since you use the same base recipe.

Ingredients (~10 cookies)

Chocolate Chip Dough

  • 4 1/2 Tbsp (1/2 stick + 1/2 Tbsp) unsalted butter, melted and cooled slightly
  • 6 Tbsp granulated sugar
  • 6 Tbsp light brown sugar, packed
  • 1/4 tsp fine salt
  • 1 large egg
  • 1 1/2 tsp pure vanilla extract
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1 cup all-purpose flour
  • 3.5 oz semisweet or bittersweet chocolate, chopped

Double Chocolate Dough

  • 4 1/2 Tbsp (1/2 stick + 1/2 Tbsp) unsalted butter, melted and cooled slightly
  • 6 Tbsp granulated sugar
  • 6 Tbsp light brown sugar, packed
  • 1/4 cup Dutch-process cocoa powder
  • 1/4 tsp fine salt
  • 1 large egg
  • 1 1/2 tsp pure vanilla extract
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 3/4 cup all-purpose flour
  • 3.5 oz semisweet or bittersweet chocolate, chopped

Topping

  • Flaky salt, for sprinkling (optional)

Make the Chocolate Chip Dough

In a large bowl, combine the melted butter, granulated sugar, brown sugar, and salt. Mix with a whisk to combine.

Add the egg, vanilla, baking powder, and baking soda. Whisk together until the mixture is totally combined and smooth.

Add the flour and stir in with a spatula until just combined. Add the chopped chocolate and stir again to distribute. You may need to use your hands to fully knead the chocolate into the dough. Set this dough aside.

Make the Double Chocolate Dough

In a new large bowl (or you can reuse the same one), combine the melted butter, granulated sugar, brown sugar, cocoa powder, and salt. Mix to combine.

Add the egg, vanilla, baking powder, and baking soda. Whisk together until smooth.

Add the flour and stir in with a spatula until just combined. Add the chopped chocolate and stir to distribute.

Assemble and Bake the Cookies

Adjust an oven rack to the middle position and preheat the oven to 400°F. Line three large baking sheets with parchment paper.

Form each dough into small balls, about 1 Tbsp each.

Press one ball of the chocolate chip dough and one ball of the double chocolate dough together. You can either gently roll them into one ball or press them into a cookie scoop to fuse them while keeping the colors distinct.

Place the combined dough balls on the prepared sheet pan, leaving about 2 inches between them. Sprinkle each cookie with a little flaky salt, if desired.

Bake one pan at a time for ~10 minutes, rotating the pan halfway through. The cookies are done when the tops are puffed in the middle.

Remove the baking sheet from the oven. Use the back of a spoon to gently press the middle of each cookie to flatten it.

Let the cookies rest on the sheet pan for 5 minutes, then transfer them to a wire rack to finish cooling.
