Funfetti Mug Cake

This fluffy vanilla cake is filled with colorful sprinkles, creating a festive cake perfect for birthdays, celebrations or whenever you need some cake.

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!

Funfetti Mug Cake


  • 4 tbsp all purpose flour
  • 1/4 tsp baking powder
  • 2 tsp granulated white sugar
  • 3 tbsp fat free milk (you can substitute with other types of milk but I found ff to yield the best results)
  • 1/2 tbsp vegetable oil
  • 1/8 tsp vanilla extract
  • 1 1/2 tsp sprinkles




1. 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.

2. Stir in 1 tsp of sprinkles. Sprinkle remaining 1/2 tsp of sprinkle on top.

3. Cook in 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.

  2. Yum ! My daughter is having a rainbow emoji party and I think these would make great party food. Just need to find a suitable cup or bowl.

  3. This is such a great mug cake! I have found it to be tastier and richer than any other cake I’ve made!!! I rate it 5/5! It’s delicious!!!!

  4. This was an amazing recipe to have during school!

  5. Could you make this in the oven if you don’t have a microwave?

  6. best mug cake ever very rich and yummy !!!!!!!!!!!

  7. It tastes good with some homemade frosting
    You will need :
    Powdered sugar
    Vanilla extract
    Mix some of these ingredients in a bowl and you should get some good frosting p.s I didn’t put measurements because I made a big batch of it.

  8. I tried out this mug cake, but it didn’t really work out for me. I have to say, it really tasted like doe. I don’t know if I did something wrong or not, but it definitely didn’t taste like it looked like in the picture. Thanks anways

    • the recipe definitely should taste like cake and not dough! are there any ingredients you swapped/substituted and did you do anything else different from the recipe? If you don’t have enough sugar and sprinkles, or leave out the vanilla, or have too much liquid in the batter, it may turn out dough-like

  9. I really liked this recipe – once I had added twice the sugar and a little bit of almond extract. I agree with the earlier commenter, without the extra sugar it tasted a lot like plain old dough,  and adding homemade frosting on top is a definite must!

    • I like my cakes a little less sweet, but definitely adjust to your liking. I also may have gotten a little generous with how many sprinkles I added.

  10. I always love ur recipes there so easy to make I recommend the chocolate chip cookie

  11. can you use canola oil instead of vegetable oil
