Can you think of any more decadent dessert option than a molten chocolate lava cake?

Even just thinking about the perfectly gooey center of melted chocolate surrounded by a moist chocolate crust is enough to get my mouth-watering.

If you like chocolate mug cakes, you will love the molten lava cake!  This cake is decadent and rich in chocolate. The gooey center will have you swooning until the next time.

You’ll be getting a double-whammy of chocolatey goodness in a totally healthy way thanks to the use of both sugar-free dark chocolate and cacao powder.

And of course, considering that this is a keto recipe, the rest of the ingredients are 100% free of sugar and flour as well!

Chocolate Keto Lava Mug Cake Recipe:

[bs_icon name=”glyphicon glyphicon-cutlery”] Servings: 1



  1. Add egg to the butter and whisk until air bubbles begin to appear.
  2. Add in stevia/erythritol, cocoa powder, heavy cream, salt, and vanilla extract, mixing until combined.
  3. Spray microwave-safe ramekins or mugs with cooking spray or line with butter
  4. Pour in batter.
  5. Place the piece of dark chocolate in the middle and spoon the remaining batter over it to cover.
  6. Place in microwave for 30-45 seconds. Every microwave is different. You want the outside of the cake slightly firm, while the middle is not yet set, that’s how you get the lava.
  7. Make sure not to overcook and the cake is still slightly uncooked so the center and top are still slightly “molten”.
  8. If you need more time in the microwave, set for 5-10 second intervals until you have the consistency of a Chocolate Lava Mug Cake.

This Chocolate Lava Mug Cake recipe can be made in the oven, too.

Simply pour the batter into an oven-safe ramekin and bake it at 350 degrees for about 13 to 15 minutes. You will know it’s done because the top will be soft like a sponge.

Let stand for 1-2 minutes before flipping onto a plate to serve. Serve immediately.

You can double or even triple this recipe and make a few more to share too!
