Keto Vanilla Mug Cake

Sweet mug cakes are some of the easiest go-to keto desserts. A couple of minutes - that's all it takes to make this treat! Even if you don't follow a ketogenic diet, you will simply fall in love with them. Just like my other recipes, these are also paleo-friendly.


  • 2 heaping tbsp almond flour (16 g/ 0.6 oz)
  • 1 heaping tbsp coconut flour (12 g/ 0.4 oz)
  • 1/4 tsp vanilla bean powder or 1/2 tsp sugar-free vanilla extract (you can make your own)
  • 1/8 tsp baking soda
  • 2 tbsp Erythritol or Swerve, or other healthy low-carb sweetener from this list (20 g / 0.7 oz)
  • 1 large egg, free-range or organic
  • 1 tbsp extra virgin coconut oil or butter, melted
  • Optional: 3-5 drops liquid stevia (I used Vanilla Stevia drops from SweetLeaf)
  • Optional topping: 2 tbsp whipped cream, coconut milk or full-fat yogurt and a pinch of cinnamon
  • Tips for substitutions: If you want to make the recipe nut-free, use 1 tablespoon of coconut flour instead of 2 tablespoons of almond flour. If you don't have coconut flour, you can use 2 tablespoons of finely shredded desiccated coconut instead.
  • Too "eggy"? Although I like this combination, some of you may perceive it as too "eggy". You can try the following: use one egg, double all the dry ingredients and add 1/4 cup coconut milk, almond milk or cream. This mixture will make 2 mug cakes. Instead of the listed sweeteners, you can try other healthy low-carb sweeteners from this list. The reason I'm using both Erythritol and stevia is to mask the aftertaste some of the sweeteners may have.


  1. Place all the dry ingredients in a mug or a ramekin and combine well.
  2. Add the egg, ...
  3. coconut oil and stevia and mix well using a fork. Microwave on high for 70-90 seconds.
  4. Tips for cooking in the oven: If you don't have a microwave, I suggest you make 4-8 servings at once. Preheat the oven to 175 °C/ 350 °F and cook for about 12-15 minutes or until cooked in the centre.
  5. When done, you can optionally top the mug cake with whipped cream or creamed coconut milk or full-fat yogurt and add a pinch of vanilla powder or cinnamon.
  6. Enjoy!
