  • In a separate bowl, create cinnamon sugar by combining erythritol and cinnamon
  • Pour cinnamon sugar onto top of mug and swirl it in.  Don't completely mix.
  • Microwave for 90 second to have a gooey center and 2 minutes for a firm muffin.

The nutrition facts below do not have the Sugar alcohols removed - There are 8 grams of erythritol which can be deducted for the net carbs. To lower the total carbs even more, eliminate the granular sweetener and add about 10 more drops liquid sweetener
