How many times have you wanted just a little something sweet in the evening after dinner? I’m guilty as charged, lol!
If I have fruit or dark chocolate on hand that’ll usually tackle the cravings, but sometimes only something really decadent will do the trick. Like cake.
The beauty of a mug cake is twofold: 1) it cooks up quickly with minimal effort, and 2) it makes just one or two servings, so you’re not left with a whole batch. Because unless we’re bringing dessert to a party most of us really don’t want an entire batch of sweets in the house, right?!
After you taste this, you’ll be surprised that this cake was made in the microwave! It has great cake-like texture and rich flavor. No bland or rubbery cakes here.
This Chocolate Keto Mug Cake Recipe has a soft, moist cake with rich chocolate flavor and a vanilla cream cheese buttercream. It almost seems wrong to be able to whip up something so delicious with such little effort. And the best part is, it only has 5g net carbs per serving.

The Inspiration for This Keto Chocolate Mug Cake
The inspiration for this Chocolate Keto Mug Cake is none other than the junk food snack Ring Dings or Ding Dongs.
If you’re not familiar with them, these treats consist of two layers of chocolate cake sandwiched together with a cream filling and a chocolate coating.
To make these little cakes even more like Ding Dongs or Ring Dings, cut the Frosting amount in half and don’t frost the outsides. After sandwiching the cakes with the frosting, freeze the cake for 15 minutes, and then dip it in melted extra-dark chocolate (I get 90% cocoa Lindt on Amazon) or stevia-sweetened chocolate (The People’s Keto Company on Amazon makes great chocolate chips).
Chocolate Keto Mug Cake Recipe
Even though it’s keto, the ingredients for this microwave mug cake recipe aren’t anything really crazy. If you have a well-stocked gluten free or keto pantry, you might have everything you need on hand!
And just like any microwave mug cake, you just mix up the ingredients and pop the batter in the microwave.
This Keto Mug Cake recipe makes two individual-sized cakes. You can enjoy one now and one later, or make one for you and your sweetie. It’s a great Valentine’s Day or date night dessert!
Sweetener for Keto Cake
This cake has just the right level of sweetness! The flavor of chocolate shines through, with nuanced depth thanks to vanilla, instant espresso powder, and sea salt, which all help bring out the flavor notes of chocolate.
Pro Tip: Instead of the allulose/monkfruit blend in this recipe, you can use the same amount of a monkfruit/erythritol blend if you prefer erythritol over allulose.
I find that for the frosting, powdered sweetener work best so the frosting isn’t gritty or grainy. However, for the cake, you can use either powdered or granulated sweetener.
How to Make a Keto Mug Cake
- Mix together all ingredients for the cake. For this recipe, I mix up the batter in a small bowl because I cook the cake in 2 ramekins, not in 1 mug. I start with the wet ingredients, and then mix in the dry ingredients with a fork.
- Spray the inside of 2 (6-ounce) ramekins with coconut oil spray and divide the batter between them.
- Microwave the cakes until cooked, about 2 minutes.
- You can the mug cakes as-is like this, or slice them in half, whip up some frosting, and assemble two little layer cakes for a dessert that feels truly special!

- 3 tablespoons powdered allulose/monkfruit blend or granulated allulose/monkfruit blend
- 1 tablespoon heavy whipping cream
- 1 large egg
- 1/2 teaspoon pure vanilla extract
- 2 tablespoons almond flour

Instructions
- For the mug cake, lightly spray the inside of 2 (6-ounce) ramekins (or same size small mugs) with coconut oil. Whisk together all ingredients, divide batter between the 2 ramekins, and microwave on high until cooked, about 2 minutes (I microwave them both at the same time).
