Gluten-Free Nutella Mug Cake Recipe (with Video)

1. In a mug, use a fork to whisk together the chocolate hazelnut spread, egg, vanilla and salt. (This takes me a good minute or so to really get everything blended.)
2. Add the almond flour, cassava flour or coconut flour and whisk that in as well.
3. Microwave for 1-2 minutes, depending on your microwave. (Start with 1 minute and add 30 seconds at a time until it looks set.)
4. Let it cool for at least 3 minutes - the cake will be hot! Top with vanilla ice cream, whipped cream and/or more chocolate hazelnut spread, if desired.
5. Bonus tip! If you want an extra-decadent version, whisk all the ingredients in a separate bowl, not the mug. Add one tablespoon of the chocolate hazelnut spread to the mug, then pour over the blended cake batter and proceed as above.
