Ingredients Equipment Method Notes

Ingredients
  

Cookie Dough Base
  • 1 cup unsalted butter softened
  • 1 1/3 cups granulated sugar
  • 1 egg room temperature
  • 1 egg yolk room temperature
  • 2 tsp vanilla extract
  • 2 1/2 cups all-purpose flour
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 cup semi-sweet chocolate chips
Chocolate Dough Add-ins
  • 1/4 cup cocoa powder
  • 1/4 cup all-purpose flour to balance cocoa dough

Equipment

  • Baking Sheets
  • Parchment paper
  • Mixing Bowls
  • Hand Mixer or Stand Mixer
  • Wire Rack

Method
 

  1. Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper.
  2. Cream together softened butter and granulated sugar in a large bowl until light and fluffy.
  3. Add egg, extra yolk, and vanilla extract to the mixture. Beat until smooth.
  4. In a separate bowl, whisk together 2½ cups flour, baking soda, and salt. Gradually mix into the wet ingredients.
  5. Stir in chocolate chips. Divide dough in half.
  6. To one half of the dough, mix in cocoa powder and the extra ¼ cup flour to form the chocolate dough.
  7. For each cookie, take a tablespoon of each dough and gently swirl together without overmixing to keep a marbled effect.
  8. Drop rounded tablespoons onto the baking sheets, spacing 2 inches apart.
  9. Bake for 9–11 minutes until edges are golden but centers look soft. Let rest 2 minutes on the sheet, then transfer to wire rack to cool.

Notes

You can freeze shaped cookie dough balls before baking. Add 1–2 minutes to bake time straight from frozen. Try topping with extra chocolate chips or a drizzle of melted chocolate and sea salt for fancy presentation.
