Ingredients

The following ingredients have 4 Servings
  • 1 tablespoon unsalted butter (14 grams, melted (⅛ stick))
  • 1 tablespoon granulated sugar (13 grams)
  • 1 tablespoon brown sugar (13 grams)
  • 1 egg yolk (14 grams)
  • ½ teaspoon pure vanilla extract (2 grams)
  • 3 tablespoons all-purpose flour (23 grams)
  • ⅛ teaspoon kosher salt
  • 2 tablespoons semisweet chocolate chips (21 grams)
  • Vanilla ice cream (optional, for serving)

Instruction

  • Spray a large microwave-safe mug with nonstick spray. Set aside.
  • In a small bowl, mix the melted butter, sugars, egg yolk, and vanilla extract together.
  • Stir in the flour, salt, and almost all of the chocolate chips (leave a few to sprinkle on top of the raw batter). Mix well.
  • Use a spatula to transfer the dough to the prepared mug.
  • Sprinkle the remaining chocolate chips on top of the dough.
  • Microwave on high for 1 minute. The top of the cookie will look set and slightly puffed when done.
  • Carefully remove the mug from the microwave and let it cool for a few minutes before enjoying. Serve with a scoop of vanilla ice cream, if desired.
