Ingredients

The following ingredients have 4 Servings
  • 1 tablespoon butter (, melted)
  • 2 tablespoons brown sugar
  • ½ teaspoon vanilla extract
  • ⅛ teaspoon fine sea salt
  • 1 egg yolk
  • ¼ cup all-purpose flour (, substitute with 1:1 gluten-free flour)
  • 2 tablespoons milk chocolate chips (, or dark chocolate)

Instruction

  • In the microwave, melt the butter in an eight-ounce mug for 8-10 seconds. Carefully remove.
  • Mix in the brown sugar and salt (if using salted butter, you will not need as much salt).
  • Add the egg yolk to the sugar mixture and whisk until fully combined. Lastly, add the flour until no dry patches remain, being careful to not overmix.
  • Fold in the chocolate chips. Add more chocolate chips to the top of the batter if you would like.
  • Microwave for 35 - 40 seconds until the cake has risen and becomes fluffy. If the cookie is underdone, microwave it for 5-7 more seconds. It is better to undercook the cookie than overcook it. The texture should be soft and gooey in the center.
  • Serve with ice cream, caramel sauce, chocolate sauce, and much more!
