3 Ingredient Keto Mug Cake (Dairy Free, Nut Free, Paleo)

Oh the mug cake! Not going to lie, the first time I heard of mug cakes I thought they were an abomination. However, I have since been converted. Alas, I am quite the mug cake connoisseur. This dairy-free, flourless, no sweetener added keto mug cake is my masterpiece!

The Evolution

At first my keto mug cake experiments were too egg. Or too dry. Then there’s the one in my upcoming cookbook, MADE WHOLE. It’s absolutely DIVINE, but definitely on the overindulgent side. Which, hey, don’t get me wrong, those recipes have their place, but it’s not your everyday mug cake. Then I have my super healthy coconut based mug cake… but this one… THIS KETO MUG CAKE is simple and elegant… and I am in love!

Ingredients Matter

You will need a GOOOOODDD dark chocolate or low carb chocolate. Lily’s Brand is the status quo. However, as of late it’s not jiving with my body. So I’ve opted for Alter Eco 85 or 90% dark that is only 4 ingredients and has less carbs than even Lily’s despite being sweetened with cane sugar. It’s so minimal, it has no effect on my blood sugar.

Next, you will need a cream. I like coconut cream for this, but my dairy-free coffee creamer works great if you have some on hand!

Lastly a large, pastured egg.

Optional ingredients include a pinch of salt (highly recommended) and if you’re really a sweet lover a few drops of liquid stevia!

  1. These are dangerously easy and look amazing! I love a good mug cake, especially chocolatey ones so I will have to check this out.

    1. So I’ve tried it with a tablespoon of sun butter instead of egg and it worked out pretty good! Like an extra thick warm pudding 🙂

  2. This looks so yummy! I am all about chocolate right now and wish I had some of this in front of me.

  3. My boyfriend and I have recently begun eating a paleo friendly diet again, and this is a lifesaver! I’ve made it twice so far and the second time, I added orange zest in because I love oranges and chocolate together. Thank you for this!

    1. I’m a fan of alter eco 85-90% dark! If I am doing unsweetened I get the Baker’s chocolate that I think nestle makes.

    1. I have! I mix the coconut cream and 2 tablespoons cacao powder, until smooth, then mix in the egg. I add a little vanilla extract and a sweetener too. then mix in the egg.

  4. Yum. this is so good. It actually remind me of those chocolate brownies that comes in microwave dinner. Similar in taste and texture, though this is much more chocolately. Soo good. I won’t be able to keep chocolate in my house ever with these bad boys around.

  5. Hi Cristina! I love this mug cake and make it probably more often than I should hehe! Last time I added a few tablespoons of peanut butter and it was divine.

    Thanks for sharing your recipes and life with us. I hope you’re adjusting well to the change of station; I was following along with your move on Instagram. We have a move coming up, too. My husband’s a marine and is not re-enlisting so we will hopefully be moving closer to family. These stressful times call for lots of healthy and comforting foods! Will likely make this cake a few more times in the coming months 😉

    I hope you and your family continue transitioning well!
