1 Person 5 min 15 min


  • 2 tbps cocoa powder
  • 1-2 tbsp So Nourished erythritol sweetener
  • 1 medium egg
  • 1 tbsp heavy cream
  • 1/2 tsp vanilla extract
  • 1/4 tsp baking powder
  • 1 pinch salt


1. Preheat your oven, if you’re using one, to 350°F. Combine your erythritol and cocoa powder and whisk to remove any clumps. This’ll make the consistency of our cake much smoother.

2. In a different bowl, beat your egg until a little fluffy. Since your lava cake is flourless, you need the aeration of the beaten egg to help coax the cake to rise.

3. Then add your egg, heavy cream and vanilla extract to the erythritol and cocoa mixture. Add your salt and baking powder as well.

4. Spray a little cooking oil into the mug, pour your batter in (ours are ceramic, you can also use ramekins) and put it to bake for about 10-15 minutes at 350° F. Do not overcook the cake or it will not flow lava! The top of the cake should be set but pretty jiggly.

5. As an alternative, you can also microwave your mug cake for about a minute. All microwaves are different, so once the minute is up, check up on your cake and if it’s still not solid but jiggly on top, put it back in for 10 second intervals until done.

6. Now it’s up to you how to enjoy it. You can eat your lava cake straight out of the mug (let it cool until you can touch the mug without burning yourself!) or top it off with ice cream, whipped cream, or all kinds of goodies. We decided to make it a molten lava cake. While still hot and in the mug, add a scoop of ice cream to the top. Then wedge a knife along the sides of the mug to help the cake unstick and place a plate onto the mug.

7. Hold the plate and mug firmly together and flip it upside down so that the mug is now face down on the plate. Tap a few times on the bottom of the mug and the cake should slide off onto the plate without a problem.

8. Now your ice cream is smooshed underneath the warm lava cake and will melt just a little. When you break into the lava cake, it warm insides and the ice cream should ooze out beautifully. Don’t delay, scoop it all up and eat it before someone gets to it first!
