How to make a Mug Cake with Cake Mix

Place your mug into the microwave and bake for about 1.5 minutes. Open microwave, remove mug and give it a moment to cool before enjoying. Psst. add frosting on top for an even more magical experience. 😉

Microwave Cake Mix FAQs

Are Microwave Mug Cakes Safe?

Yes, the cake is fully cooked and becomes hot enough to bake just as you would in the oven, just in a smaller portion!!

Why are Mug Cakes Mushy?

This mug cake should not be mushy, if it is, it hasn’t been cooked long enough.

Can I use milk instead of water for my mug cake?

Sure- that shouldn’t change anything but make the cake taste more rich!

    I had doubts, but this mug cake was delicious! We made some icing separately and put it on the mug cake, and there was no way I could tell the difference between that and cupcakes I’ve made before with the same cake mix.

  2. Thanks for posting. I used what I had on hand 4 tbs white cake mix, toasted pecans, 4 tbs unsweetened vanilla almond milk and added a touch of dark maple syrup….140 seconds…it was great. Thanks!

  3. I haven’t tried this myself so I can’t say for sure. If you give it a try, let me know how it goes!

    Worked amazingly and so delicious! So much cheaper than buying the expensive mug cake individual servings! Brilliant!

  5. Thank you for sharing this. After two failed cake orders, and with a fussy baby, this recipe saved the (birth)day. I can’t believe it worked. I tripled the recipe and I’m at about 5000 feet elevation so I threw in an extra tablespoon of flour and water. Thanks again!

  6. Got creative with bits of this and that left from holiday baking —
    Lemon cake mix
    Pumpkin spice coffee creamer
    A couple of pecan and walnut halves
    Dried cranberries, a few raisins, a chopped date, and a little shredded coconut.
    Topped with a bit of canned cream cheese frosting.
    OMG, it was a party in my tongue!
