  • 1 tbsp unsalted butter
  • 1 1/2 tbsp light brown sugar
  • 1/2 tbsp granulated sugar
  • 1/4 tsp vanilla extract
  • 1 large egg yolk
  • 3 tbsp all-purpose flour
  • 1 pinch salt
  • 1 pinch baking soda
  • 3 tbsp semi-sweet chocolate chips


  • Spray a large or medium-sized mug with baking spray. Place butter in mug and melt in microwave for 10-15 seconds. Stir in sugars, vanilla, and egg yolk. Whisk with fork to blend. Stir in flour, salt, and baking soda until blended. Stir in chocolate chips. Microwave for about 40 seconds—you may like it a bit more done but don’t exceed 60 seconds!
