Ingredients

Mug Cake:

  • 1/3 cup all-purpose flour
  • 2 tablespoons sugar
  • ¼ teaspoon baking powder
  • 1/8 teaspoon fine sea salt
  • 2 tablespoons unsalted butter melted
  • 1 egg yolk
  • 3 tablespoons whole milk
  • ½ teaspoon vanilla extract
  • 2 teaspoons rainbow sprinkles

Frosting:

  • 1 tablespoon salted butter ; softened
  • 1/4 cup powdered sugar
  • ½ teaspoon milk
  • 1/4 teaspoon vanilla extract

Instructions

To Make Mug Cake:

  • In a large coffee cup (12 ounces or larger), stir together the flour, sugar, baking powder and salt.
  • Add the melted butter, egg yolk, milk and vanilla extract. Stir until it forms a thick cake batter. Stir in the sprinkles. Scrape down the sides.
  • Microwave for 70-80 seconds. If it still looks doughy, microwave in 10 seconds intervals. Microwaves and the width of mugs vary greatly, so it can take some time to get the right amount.
  • Remove and allow to cool slightly before frosting.

To Make Frosting:

  • In a small bowl, combine the butter and powdered sugar until smooth. Add the milk and vanilla. Use a drop of food coloring, if desired.
