This lightly sweetened paleo and vegan chocolate mug cake is a delicious, one-serving treat, which can be made in only a few minutes! Free of grains, gluten, dairy, eggs, and refined sugar too!
My family and I do a fast each January. One year we fasted television, another we fasted coffee. This year we decided to fast grains. After all of the holiday indulgences, my body definitely needed a break. Although I haven’t been tested for particular food sensitivities, there are several grains that tend to make me feel bloated and heavy. I can definitely tell a difference in my body when I avoid grains, which makes me sad because I definitely loooove eating rice, oats, pasta, bread, etc.!
Well, I of course had to find a way to get some yummy grain-free treats in because we all know I have quite the sweet tooth! While I’ve been enjoying my grain-free brownies, fig bars, and chocolate chip cookies, what I really wanted was some cake! So I went into the kitchen determined to create a good paleo + vegan friendly mug cake that I can quickly make throughout the month whenever that sweet craving hits.
I gotta be honest, trying to combine grain-free flours to create a fluffy cake-like texture without eggs is not easy. In fact, I went through many practice mug cakes, several of which were completely inedible. I worked with different combinations of flours, trying variations of almond, coconut, tapioca, and cassava flours.
Some were gummy, some grainy, and some didn’t set at all. But eventually, I got it! A fluffy and delicious chocolate cake that my daughter claims doesn’t even taste grain-free! She actually thought I made her break her fast by giving her a mug cake made with regular flour! 😂
Fudgy chocolate cake that’s free of grains, gluten, dairy, eggs, and refined sugar. I can’t think of a better treat to celebrate the weekend! Even better that it can be made in just a few minutes! Hope you enjoy it, friends!

Hi is there any way I can just use gluten free flour like bobs?
Hi Misty, I’m not sure how that would work without testing it, but I do have another similar mug cake that uses gf flour here: https://www.wifemamafoodie.com/chocolate-lava-mug-cake/
Let me know if I can help you find anything else!
