TOP TIP FOR MUG CAKE
Since we make these single serving cakes to take to birthday parties, I actually like making ours in ramekins. It's a little more discreet than a mug with a handle, and my kiddo prefers that. This recipe works perfectly in our 6-ounce ramekins. But of course, mugs are always fun at home!
It was nine in the morning. Skating birthday party at ten.
Wrap gift. Make card. Get breakfast done.
Pack 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. Did hubby make cupcakes?! Crud, we forgot to make safe cake!
Now it's 9:15 am. Thirty minutes to show time. Think. QUICK!
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.
So I pulled up our dairy and egg free cake recipe and started cutting down the measurements bit by bit.
Tweaked a little here, tweaked a little there. And kept tasting the batter until it was good to go.
No milk, no egg. We got this!
I grabbed a six ounce ramekin from the cabinet, threw in the batter, and had cake in a minute.
Thankfully, we had some canned icing in the pantry.
Then after icing (and sprinkles, of course), I put the ramekin into a small plastic container with a lid. And off we went!
The kids had a blast at the party, of course roller-skating was the highlight...not the food.
But kiddo really loved his discreet, single-serving, allergy-friendly cake.
This recipe is a winner, especially for cake-on-the-go for food allergy families.
If you don't have frosting in the house, a little powdered sugar sprinkled on top will do just as well.
Or sprinkle with chocolate chips before you microwave.
I share our favorite store-bought tubs of icing below, too. Dairy-free, of course.
Hopefully, the next time YOU forget to make safe cake an hour before a birthday party...
this will save you like it did me!
MUG CAKE REVIEWS
"This tastes exactly like chocolate cake! Would recommend this to anyone. I had no milk at home, so this was perfect!" Pinterest Reader
"Actually delicious! We made this as a friend group and it was so much fun and turned out great and moist!" Pinterest Reader
"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 (just a little) 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!"

4 tablespoons flour
1 tablespoons sugar
1 tablespoons cocoa powder

DAIRY-FREE FROSTING
During the depression, our grandmothers just sprinkled this cake with powdered sugar.
Or you could easily sprinkle chocolate chips on top before microwaving.
Here are some quick dairy-free frostings we've used for mug cake, as well.
And while we are at it, we and our members our loving these natural & allergy-friendly sprinkles that contain no soy. I love how white they are, perfect for showcasing on chocolate icing!
Hope you love this microwave mug cake as much as we do!

Hi looks great, cant wait to try it. It seems like this would make quite a big serving though. Is half a cup of flour not too much. Just checking so i dont make a mistake...
That's right, Romi. 🙂 It's makes two small cakes or one larger one. Always good to have a back-up especially with food allergies. 🙂
Can gluten free flour be used?
Usually our readers have luck subbing cup for cup gluten-free flour in our recipes. It's worth a shot! Let us know!
I love your blog!! This recipe was a life saver-my daughter is going to a party tomorrow and I didn't know what to make for her-this is perfect!! Thank you!
Oh, so happy to hear that! Hope she loved it. 🙂
I love your blog!! My daughter is allergic to egg and dairy products. Most recipes call for vanilla extract. Should that be a concern ?!
Thanks so much! Glad to have you here. We found a brand we like and stick to it. That's the same with most spices and extracts for us. 🙂 Hope that helps!
I just made this in a big chicken pot pie, had to cook it for longer but wow, I cannot believe the difference this is going to make on our holiday's and last minute cake making ideas. Thank you so much it tastes really nice, my daughter was amazed!
You are so welcome, Lee-Ann! Thanks for sharing! So glad your daughter was thrilled. 🙂
Oh, I hope you liked it, anonymous!
Thanks so much for this recipe...I have to try it out with my little guy. We just found out that he needs to avoid eggs & milk. This is will help so that he does not have to feel left out when we go to parties or when he sees cupcakes in the store and wants one.
