Ingredients

For the cake:

  • 3 Tbsp yellow cake mix or you can use white
  • 2 Tbsp water
  • 1/2 tsp oil
  • 1 Tbsp Rainbow sprinkles

For the frosting:

  • 2 Tbsp butter
  • 1/4 cup powdered sugar
  • Dash vanilla
  • Pinch salt
  • 1/4 tsp milk if needed
  • 1/2 Tbsp Sprinkles

Instructions

  • Mix together cake ingredients in a mug. Microwave for 45-60 seconds depending on your microwave. Check your cake with a toothpick to see if it's done.
  • While the cake cools, make your frosting. If your butter is cold microwave it for 5 seconds. Whip it really well with a fork. When whipped add powdered sugar and whip until incorporated. Add vanilla, salt, and if needed milk. Mix again. Spoon over cooled (or at least mostly cooled) cake.
  • Top with sprinkles.
