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. Ok so I made this recipe with four 7 year olds. Didn’t turn out so well. When we mixed it all together every single one was do dry and hard like dough. We tried adding milk and four to get the write consistency. When we got the final consistency it took 5 minutes to cook. Maybe just our microwave? when finally finished it was like putty. To sugary and sooo gross. Kids loved it me not so much. I made it again and turned out great! I don’t know what I did wrong?

    • When you made the multiple mug cakes, did you make each individually or did you scale up the recipe? When we make more than one mug cake, we measure out the ingredients for each one and cook them separately.

  2. Hands down best mug cake recipe ever! This is the only mug cake recipe that actually worked for me and actually taste great! I added a tiny bit more sugar and vanilla to really get that sweet sweet vanilla cake taste, added white chocolate chips in addition to the sprinkles. Topped it with some dairy free butter, and it hit the spot. I don’t ever write recipe reviews but man, this is gonna be my go-to snack for a while haha.

  3. this was so good! I made it for my mom and I and it was DELICIOUS! I had to bake it for 1 min 20 sec but that’s just our goofy microwave. TYSM
