I normally only eat funfetti cake at birthday events but I had a huge craving for it recently. So I finally made myself one. After all, it’s someone’s birthday somewhere, right?

This cake starts with an easy vanilla cake base, and then I stirred in some sprinkles into the batter and added some on top. The end result is a fluffy cake bursting with little dots of color, especially when you dig in.

You can eat it on its own, or top it with some whipped cream or other topping. Or a candle if you really are celebrating someone’s birthday! If you like this cake you might like my other birthday mug cake or funfetti milkshake!

  • 4 tbsp all purpose flour
  • 1/4 tsp baking powder
  • 2 tsp granulated white sugar
  • 3 tbsp fat free milk (see note)
  • 1/2 tbsp vegetable oil
  • 1/8 tsp vanilla extract
  • 1 1/2 tsp sprinkles


  • In a microwave-safe mug (that can hold at least 8 oz of liquid), add flour, baking powder, sugar, milk, oil, and vanilla. Mix with a small whisk until batter is completely smooth.
  • Stir in 1 tsp of sprinkles. Sprinkle remaining 1/2 tsp of sprinkle on top.
  • Cook in the microwave for about 1 minute, or until cake looks done. Let cake cool a few minutes before eating. Cake is best consumed right after the few minutes of cooling time.


  • You can substitute with other types of milk but I found fat-free milk yields the best results.

  1. It was super easy to make and I loved how it turned out! I used whole milk and it worked just fine!

  2. Oh my gosh. This is AMAZING!! I have been trying to find my favorite mug cake and this is it. It didn’t explode or drip over the sides it was perfect small and delicious! I have made this over 3 times now and it still is amazing. But it is very important that you use a whisk. Or else it can turn purple or a mix of all the sprinkle colors. But if you like that cool.

  3. if I could tell you how much I liked these recipe from 1 /10 I would choose 10/10 ,GREAT JOB keep it up

  4. A little plain but with chocolate syrup it’s good.

  5. I love this cake so good. But I use cake flour instead of all purpose it gives it more of a cake taste.

  6. Best mug cake ever. Thank u sooooo much. It was delicious ?.  

  7. Omg this was such a good recipe for right before bedtime TYSM!
