A low carb, keto microwave mocha mug cake recipe for an easy keto dessert made in less than two minutes all in one mug.
“I’d love to do keto, but I could never give up chocolate.” It’s a phrase I hear said wistfully by a lot of friends and people in my social circle who are interested in, but hesitant of, trying the keto way of life.
Let’s address it here and now, with this recipe serving as a piece of gooey, rich, chocolatey evidence: You don’t have to give up the foods you love on keto, you just have to adjust them and look at them in different, creative ways.
Just because you can’t visit the bakery any more, doesn’t mean you can’t become your own personal ketogenic baker!
Chocolate cake can be on the menu of any ketogenic dieter. The enemies of a strict carb count in a regular chocolate cake are the flour and the sugar. We’ve simply substituted those for more low-carb-friendly options in Stevia and almond/coconut flour, and instantly we have a chocolate cake that tastes as good as any sugar-packed version, but with only a handful of net carbs per cake!
Microwave mug cakes have become an obsession of mine lately. There’s a couple of reasons for this. First and foremost, they’re easy and super quick. You can go from craving to eating in less than five minutes, which is always a bonus when the chockie-monster comes calling from the kitchen in the middle of an episode of Teen Mom or The Bachelor. You can literally make a mug cake in a commercial break, if you hurry!
Secondly, you can do most of your cooking in the mug itself, so there’s none of the usual post-baking-blues of a sink full of sticky baking tins, bowls, and so forth. One cup, one stirring utensil, a couple of measuring spoons, and you’re set.
Most importantly for those of us trying to lose pounds and keep in control of our cravings, though, mug cakes are a single-serving, easy-to-control portion size. Just because chocolate cake can be keto friendly, doesn’t mean that eating too much of it is going to do you any favors. And that’s why mug cakes reign supreme: they fill the craving hole and don’t leave you the option to keep picking, and “just one more slice-ing” your way towards a ruined day, week, or even a completely derailed diet. With a mug cake you measure very small quantities of food into a small serving size that can be easily calculated to fit your macros. You can even adjust the quantities in the recipe, so long as you keep the ratios the same, in order to make yourself a bigger or smaller mug cake that fits your macros better.
In case you can’t tell, mug cakes are my jam right now. Without any further waffling, here’s a recipe I’ve been working on lately that is dark and broody. All those who fear strong coffee and dark chocolate, turn away now! This one packs a bitter-yet-slightly-sweet punch and a caffeine pick-me-up that will pep you up at the same time as making you feel like putting your comfy pants on. Like all mug cakes, it’s simple and focuses on small quantities of a few key ingredients.

Here’s how to make Keto Microwave Mocha Mug Cake.
- 2 tbsp almond flour (not almond meal)
- 1 tsp coconut flour
- ½ tsp baking powder (not baking soda)
- ½ tsp vanilla extract
- 1 large egg
- 2 tbsp butter
- 2 tbsp unsweetened cocoa
- ½ - 1 tbsp stevia powder or other artificial sweetener (use more if you prefer more sweetness, less if you like to taste those bitter coffee and chocolate notes)
- 2 tbsp strong coffee or espresso (choose decaf if this is a close-to-bed-time dessert
- pinch of salt
- Start by melting your butter in the microwave in the mug you plan to cook in, so it’s almost completely liquidized. This should take between 20 and 30 seconds, depending on your microwave.
- Add the cocoa powder, sweetener, almond flour, coconut flour, baking powder, salt, coffee, vanilla, and egg in that order. (I’m not convinced the order matters too much, but I am a creature of habit, and this is the order I’m used to following.)
- Whisk the ingredients together thoroughly inside the mug until the mixture is as smooth as possible. Be particularly sure that you’ve scraped all ingredients away from the bottom and sides of the mug and that everything is incorporated. If not, you’re going to discover the spots you missed when your cake is cooked!
- Cook on high in your microwave for between 60-70 seconds, depending on your microwave. In my experience, no two are the same, and your first few mug cakes might take some experimenting to find the right time for your particular model. Remove from the microwave and inspect; the top should still be slightly gooey but the overall cake should have roughly doubled inside and the sides should be lifting away from the mug a little, indicating the cake is cooked.
- Slide a butter knife around the inside of the mug to ensure the cake comes away, and tip the mug upside down onto a plate if you’d like to present your cake like the one pictured on this page. But I’m not going to judge you if you want to eat it straight from the mug. It means there’s one less dish to wash, and besides, if my timing calculations are correct, The Bachelor just came back on and it’s time to race back to the couch with your mug in hand! Bon appetite!
