Microwave Mug Cake Recipe: Funfetti and Chocolate

Last Updated on October 5, 2026 by Mr. B

Sometimes you just want a dessert without all the time and effort. That’s where this cake in a jar recipe comes in! All you need for this microwave mug cake recipe is a few minutes (and ingredients), a mason jar (or mug if you prefer) and a microwave!

I made these mug cakes in two different flavors, Funfetti and Chocolate (with a little bit of caramel thrown in). Frankly, I couldn’t choose just one that day! Call me greedy! You can make your favorite out of the two or make both like I did.
