My 5-ingredient Gluten Free Mug Cake is the perfect single sized treat. Make this when you’re craving dessert, but don’t want to take time to bake a full cake. This simple recipe calls for almond flour, cacao powder, egg, maple syrup, and baking soda, and will satisfy your sweet tooth in a healthy way!
We love mug cake! It’s so cute that I had to make my own gluten-free Paleo Mug Cake so that we could indulge in this fun trend. Many mug cakes are baked in a microwave. I don’t like to microwave my food, let alone my body, so I bake this cake in the oven. Yes, finally a no microwave mug cake!
I think it’s funny that so many of the same people who wouldn’t ever heat their food in a microwave, hold a phone (which uses the same technology) to their head all day. For more on how I’m reducing my exposure to microwave radiation, also known as radio frequency radiation (RFR), you’ll want to see my write up on Simple Steps to Reduce EMF’s.
But back to fun stuff, like this Gluten Free Mug Cake! I used a 10 ounce mug to make this healthy little cake and bought these cute cat mugs online. If you use a mug that is bigger, it will seem like your cake did not rise enough. Really though, the issue with using an oversize mug, larger than the one I recommend, is that the batter will not fill it.

Since this is an almond flour mug cake it is the moistest you will ever have. My Gluten Free Mug Cake is not dry like all of the other mug cakes out there. I worked on this recipe for over a year to get it just right for you.

Hi Elana,
Is there a natural ingredient I can use to replace the egg in this recipe? I’m allergic. Thanks in advance!
Elana says
Alisha, I haven’t tried that so not sure. Here’s a link to my Egg-Free Recipes page for you:

I tripled the recipe, added a pinch more cacao powder and almond flour, divided the batter among three ramekins filled about 2/3-3/4 full and it came out great. I also put a few chocolate chips on the tops right after they came out of the oven and everyone loved it!
Elana says
Sarah, I’m so happy to hear that everyone loved this!!!

Ayelet says
Thanks for the recipe, will def. try it, looks tasty.
Just to make sure:
*Can I multiply the ing. by the number of cups I am preparing, and then pour into the cups?
*Also- Should I oil the cup before hand?
Thank You !!
Elana says
Ayelet, no need to oil the mug for this recipe. I haven’t tried multiplying the ingredients so not sure if that will work :-)
Sharon Brill says
I needed to spray the mug. The first mug stuck to the sides and bottom of the cup. Taste and consistency was good.
Elana says
Sharon, I’m so happy you enjoyed this!
Stephanie says
How to be sure the mug can be placed in an oven safely?
Elana says
Hi Stephanie, thanks for your question! The mugs I used in the photo worked very safely for this recipe. Feel free to purchase them or experiment with mugs of your own :-)
Lynn says
Can this be made with a flax or chia egg?
Elana says
Lynn, I haven’t tried that so not sure. Here’s a link to my Egg-Free Recipes page for you:

Debra says
I can’t wait to try this! I tossed my microwave over two years ago, and only use my oven now. I rarely use my cell phone either, tho we live quite isolated and have to have one . Not fond of it, but have it.
Thanks for all the great recipes!
Elana says
Debra, you’re welcome!
Christianne Madona says
Thanks so much Elana. We are just 2 in our home except for the 4 leggers and we avoid the microwave as well. So thanks for the conventional oven details!
Elana says
Christianne, you’re welcome!
