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.
Serve my Gluten Free Mug Cake with these amazing toppings!

Hi Elana. The recipe sounds delicious. I’ve never thought about putting a mug in the oven. Any idea if most mugs would be safe? Thanks!
Elana says
Valorie, thanks so much! The mugs that I used in the photo of the cake worked every time :-)

Canada; These little cakes are now baking, in mini bowls, they look so cute with their little round bellies..Well 25 min. and they seem too soft on top, not springing back, I used substituted eggs. Hope they turn out..I left them in, 5 more minutes. Perfect, they are now harder on top. We’ll see how they taste tomorrow. I added dried cranberries and crushed almonds o the individual batter. It’s the Christmas season!! My husband will whip up an avocado chocolate maple syrup sauce to be served with them. This is usually a custard.
Elana says
Laura, I hope you’ll let us know how your experiment turned out!
Debbie says
Can you use a gluten free almond free flour? Hubby is allergic to almonds. Like Bob’s Red Mill Gluten Free All Purpose Flour? Thanks.
Elana says
Debbie, I haven’t tried that so not sure. I’m sorry I can’t be of more help. I went grain-free in 2001 and haven’t eaten any of the usual gluten-free flours since then :-)
Jon otte says
Can maple syrup be replaced by stevia
Elana says
Jonotte, I haven’t tried that so not sure. If you do experiment please let us know how it goes :-)
Marie Edwards says
Thank you for a no microwave mug cake recipe. I have been missing this simple and satisfying treat while reducing microwave use.
Elana says
Marie, you’re welcome!
Allison Thompson says
Hi Elana,
Love this recipe and your blog. Would I be able to make this in the microwave as well, rather than baking in the oven? If so how long would it need?
Elana says
Allison, I don’t own a microwave so not sure. If you do experiment, please let us know how it goes :-)
Beth says
This sounds delicious, and I love the idea that it is a single serving desert :)
We are currently travelling and unable to find cocoa powder. We will try this when we get home.
Thanks for such a unique and healthy recipe :)
Elana says
Beth, you’re welcome!
Sara Gordon says
Could you divide this and put it in ramekins? How much does it rise?
Elana says
Sara, I haven’t tried that so not sure, if you do experiment please let us know how it goes :-)
Karen says
I used a Pyrex Bakeware Custard Cups, 10-Ounce, that worked perfectly.
Lori says
Wow, super easy dessert! Just tried it on my hubby. I sprinkled some chocolate chips on top right after pulling it out of the oven. It is very moist. His comment, “very rich”. Thanks for this easy creation Elana!
Elana says
Lori, you’re welcome! I’m so glad to hear you found this to be a super easy dessert and that your husband enjoyed it!
