  • T Nutella or favorite chocolate hazelnut butter
  • 1 large egg
  • 1 - 2 teaspoon sugar or sweetener
  • 1 T unsweetened cocoa powder
  • ½ teaspoon vanilla extract
  • Dash of sea salt


  • Whisk ingredients together in a small bowl.
  • Pour into a microwave safe mug.
  • Microwave for about 60-75 seconds. It will expand pretty high so look out!!! I find 90 seconds dries it out too much.
  • Let cool for several minutes and then eat it straight from the mug if you like! And extra dollop of nutella on top is always amazing as well.


  • All microwaves are different so the you may need to cook yours a touch longer or not as long. I keep a pretty good eye on mine and you can tell when it's about ready because the cake will rise and it will not look wet any longer.
  • Use a mug with sides that go straight up. You want the Nutella mug cake to expand up and cook evenly.
  • Start cook time at one minute. If a toothpick doesn't come up clean, you can add another 30 seconds.
  • Sweeten to your own taste. Since Nutella and most chocolate hazelnut spreads are already sweetened, you won't actually need too much but a little still is really nice to round out this rich treat in my opinion. IT will cut some of the bitterness from the cocoa powder for sure.
