  • In a small greased/oiled bowl or mug, whisk together your dry ingredients above.
  • Next add your butter, egg yolk, heavy cream and extracts. Mix well until a thick batter forms. Add your sprinkles.
  • Smooth out the top as best as you can and microwave for 1min. (Depending on your microwave it will take more or less time, start on the lower end with 45s if your microwave tends to bake hot, if your microwave works slow like mine then you may need 1min 15s total).
  • Whisk together the frosting ingredients above and top your Keto Funfetti Mug Cake OR top the warm cake with ice cream and/or homemade whip cream. Enjoy immediately!

  • If you want your cake to come out cleaner/prettier looking, your can make it in a separate bowl then grease a mug or ramekin and use a spatula to neatly pour the batter in.
  • I have yet to try it but I think this cake would also be great in the oven! Give it a shot by baking it at 350* for 10min or until a toothpick comes out relatively clean.
  • This cake goes great with all kinds of toppings so feel free to get creative.
  • You can lower the calories of this cake by adding 1 tbsp almond milk instead of heavy cream if you'd like and/or 1 egg white instead of the egg yolk!
