This Low-Carb Double Chocolate Mug Cake is gluten-free, nut-free, and can be made and enjoyed in minimal time! Featuring ingredients like cocoa powder, sugar-free dark chocolate bar pieces, and powdered monk fruit sweetener, this double chocolate dessert is sure to satisfy your dessert craving!



  1. Whisk together ground sunflower seed meal and cocoa powder until light and fluffy. Ensure there are no clumps. Transfer to microwave-safe mug and whisk in remaining dry ingredients.
  2. Add sour cream, egg yolk, heavy cream and, using a fork, mix until ingredients are well-combined. Add in chocolate bar pieces and mix again.
  3. Let batter settle in mug for 1 minute before transferring mug to microwave to cook for 45 seconds – 1 minute (my microwave is 1000 watts and I cooked my mug cake for 1 minute).
  4. Allow to cool slightly before serving.

Recipe Notes:

Sugar-Free Sea Salt Extra Dark Chocolate Bar Substitution: I use Lily’s brand chocolate bars for this, but a plain dark chocolate bar will work too. If you use a bar that is plain dark chocolate, I would suggest adding a pinch of salt to your mug cake.
