This chocolate mug cake is the ultimate easy keto dessert you can make in less than 4 minutes in the microwave. This chocolate cake in a mug is a fabulously simple sugar-free, gluten-free, grain-free no-bake low carb dessert that’s rich and decadent and requires no special ingredients and practically no effort. 




  • Melt the butter in the mug or ramekin in the microwave – this takes my microwave 30 seconds. 
  • Next, mix in the cocoa powder, followed by the erythritol, baking powder, cream, vanilla, and the egg.  
  • Make sure you stir it well so the consistency will be right. Don’t worry; this will only take you a minute. 
  • You may want to grease the mug with butter or a little gluten-free cooking spray if you aren’t planning on eating the cake straight outta the cup 🙂 
  • I microwaved mine for 1 minute + 30 seconds, and it was perfect. It may take your microwave less time, so check-in after a minute, so you don’t overcook it.
