Low-Carb Red Velvet Mug Cake

This 2-minute mug cake is a real treat for Valentine's day! It's moist, rich in flavour and the frosting takes it a step closer to real red velvet cake. The beetroot powder that I used in this recipe gives the mug cakes a pink tint. If you want to achieve a deep red colour, you will have to use a few drops of red food colouring. The products I found in the UK either contained unwanted additives or sugar so I avoided using any food colouring. For more Valentine's day treats, check out more of my ketogenic recipes.

Ingredients (makes 2 servings):

Mug Cakes:


  1. Place the almond flour, coconut flour, cacao powder, beetroot powder, baking soda, Erythritol and vanilla powder in a bowl and combine well.
  2. Add the eggs, melted coconut oil and sour cream and mix until well combined.
  3. Divide the mixture between two mugs. Microwave each mug cake on high for 70-90 seconds. Meanwhile, prepare the frosting by mixing the butter, remaining Erythritol, cream cheese and vanilla. For a smooth texture, use a blender. Instead of the frosting, you can use whipped cream or creamed coconut milk with a dash of vanilla.
    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 20 minutes or until crispy on top and firm inside.
  4. Let the mug cakes cool down. Place the frosting in a piping bag or simply spoon it on top of each mug cake. Enjoy!
