Single Serve Chocolate Chip Cookie

Prep Time 8 minutes
Cook Time 15 minutes
Total Time 23 minutes
Servings 2 -3 large cookies


  • 3 tablespoons salted butter, at room temperature
  • 3 tablespoons packed brown sugar
  • 1 and 1/2 tablespoons white sugar
  • 1/2 teaspoon vanilla extract
  • 1 large egg yolk (discard or save whites for another recipe)
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon cornstarch, optional
  • 1/2 cup white, all-purpose flour
  • 6 tablespoons chocolate chips (we prefer milk chocolate)


  • Preheat the oven to 350 degrees.
  • In a bowl, beat together the ROOM TEMPERATURE butter (if it is melted at all these cookies will be flat. Don't microwave it) with the brown and white sugar until creamy.
  • Add in the vanilla extract, egg yolk, baking soda, and cornstarch. (Add 1/8 teaspoon salt here if using unsalted butter)
  • Beat until just combined.
  • Add in the flour and chocolate chips and beat until just combined.
  • Form 3 evenly sized, large and tall balls of cookie dough
  • Place the cookie sheet with cookie balls in the freezer for 15 minutes.
  • Remove and immediately bake for 9-14 minutes or until very lightly browned around the edges. (Cookies are always best slightly under-baked!)
  • If desired (pretty appearance + more chocolate!), press a few additional chocolate chips into the tops of the cookies right after pulling them out of the oven.
