1-Minute Microwave Mug Cake

1-minute microwave mug cakes are so fun and handy in a pinch.

What if they could be made with no milk or egg? They can!

Be sure to watch our mug cake video in this post and check out the gluten-free review, too.

It was 9:00 in the morning. Skating birthday party at 10.

Wrapping gift. Making card. Getting breakfast done.

Packing lunches for the predictable pizza fest that would ensue in the next couple hours for a bunch of 10-year-old boys.

But not my boy.

He’s allergic to milk, and I have to make his own safe food, always.

Then it hit me. “Jeff, did you make cupcakes?”.

Ooooops, we forgot to make safe cake!

Now it’s 9:15. Thirty minutes to show time.

Quick, THINK!

It was time to revisit the microwave mug cake idea.

I’d been wanting to create this recipe forever.

And there was no better time than the present.

I pulled up our dairy-free and egg-free cake recipe and started cutting down the measurements bit by bit.

Tweaked a little here and tweaked a little there.

And kept tasting the batter until it was good to go.

Remember, no egg.  🙂  

Using larger ramekins (affiliate), I ended up with a recipe that made two little cakes.

Seriously, how cute!

Why a ramekin when mug cakes are all the rage?

Well, at a birthday party with a dozen boys, I know my son would be horrified eating cake out of his mother’s coffee cup.

The ramekin is super discrete and no big deal.

We threw the ramekin cake in a rubber maid container (affiliate) with his own plastic fork, great for travel.  

I will love having this recipe on hand, now, and the kids can make cake whenever they want!

If you don’t have frosting in the house, a little powdered sugar sprinkled on top will do you well.  

And hopefully the next time YOU forget to make safe cake an hour before a birthday party, this will save you, too.

We hope you like this helpful video and then the written recipe is below.

Milk Allergy Mom Members, our member library has a printable recipe sheet for your allergy binders. And we have a Kids in the Kitchen video waiting for you and your kiddos, as well! Mu-ah!

The recipe is below.

And we have a quick microwave cake video in this post, as well.


No Milk, Egg, Butter Mug Cake



“When you want to make your friend a last minute birthday cake, but it has to be egg free. 100% recommend this allergy friendly mug cake by Milk Allergy Mom. It was super easy and the texture was great. It’s completely dairy and egg free. You could probably make it gluten-free too since it’s only 1/2 cup flour. Seriously, give this a try!” 

“Recipe worked great! I substituted rice flour (gluten-free), coconut palm sugar (fructose-free) and used MCT oil. Turned out perfect even with the substitutes. Thanks for the great recipe!”




1/2 cup flour
1/4 cup sugar
2 Tbs cocoa powder
1/4 tsp baking soda
1/4 tsp vinegar
1 tsp vanilla
1/3 cup water
1 Tb oil
2 pinches of salt

Mug Cake With No Milk or Egg



Mix ingredients together in a small mixing bowl. 

Grease 2 large ramekins or 4 small ramekins with dairy-free butter.

Fill ramekins half full with batter.

Microwave large ramekin cakes for 1 minute or small ramekins for 30 seconds.

If you decide to do the oven instead of the microwave, the cakes will take 15-20 minutes. Done when a toothpick comes out clean.

Let cool and top with frosting or powdered sugar.  

Here are frosting options.
