Ingredients
- 1 egg - beaten
- 1 tbsp unsweetened cocoa powder
- ¼ tsp baking powder
- ½ tsp vanilla extract
- ½ tsp almond extract
- 5 grams Keto-friendly chocolate chips - (about 1 heaping tsp)

🔪 How to make
Keto mug cakes are the best thing since the microwave itself, and I am not even a fan of microwaves. Still, when making chocolate cakes, I will gladly put aside any griefs I have to bake my keto chocolate mug cake!
Instructions
- Heat the mug with butter inside for 10 seconds in the microwave or until the butter is melted. Swirl it around the mug so it covers the inside. You can also use cooking spray if you prefer.
- Mix the whipped cream and the beaten egg until combined. Add the almond and vanilla extracts, and continue beating the mixture until fluffy.
- In the other bowl, mix the baking powder, erythritol, and cocoa powder until well combined.
- Pour the dry ingredients in the mug first and then the wet ones, stirring with a fork until the chocolate cake batter is smooth and velvety.
- Place some sugar-free chocolate chips on top of the mixture and microwave for 90 seconds on high. Depending on the power of your microwave, you may need an additional 30 seconds.
- To know if the keto mug cake is ready, stick a toothpick through the center, and if it comes out with a little bit of mixture stuck on it, it's ready!
- Remove the mug from the microwave and serve warm as it is or scoop it out onto a plate with some crushed raspberries or a topping of your choice.
💭 Top tips
- Whip up some extra heavy cream to add to the mixture and on top to serve.
- To make an airy chocolate mug cake, add a small tsp of baking soda to the dry mixture.
- If you want a super chocolatey cake, add some melted sugar-free chocolate chips to the mixture and some on top for a rich chocolate flavor.
📋 Variations
- For a coconut chocolate mug cake, add 20g of coconut flour and 20g of coconut flakes to the dry ingredients, and substitute the regular cream for coconut whipped cream.
- To make it dairy-free, substitute the butter for coconut oil and use coconut cream instead of whipped cream.
🧂 Toppings
Keto desserts like the keto mug cake are great for people on a low-carb diet and want to watch their carb and calorie intake. But if you feel like the mug cake needs some toppings, then try some of these sugar-free suggestions and also toppings for a sweet tooth.
- Keto Ice cream: Keto recipes are always low on sugar, so having this ice cream as a topping sounds delicious and tastes fantastic with mug cakes.
- Peanut Butter: Nothing beats chocolate and runny peanut butter together. Use natural peanut butter with no added sugars to mix through the cake and enjoy!
- Berries: You can use any berries for this great recipe like strawberries, raspberries, blackberries, or even cherries. Whatever is in season is an excellent topping for healthy recipes.
- Caramel sauce: This is my go-to dessert! I love sugary desserts with anything caramel, but luckily you can find sugar-free caramel sauce, which is insanely tasty with mug cakes. MUST TRY!
🥫 Storage
Although this recipe is best cooked at the time of need, as it only takes a few minutes to prepare, you can also eat half if you made a big mug portion and save the rest for another time.
It is possible to store the cake in the fridge for up to 2 days once it has cooled down. The cake may become a little dryer than it was, but it will still taste OK.
You can reheat it again in the microwave for 30 seconds.
