Notes

Chef Jenn's Tips

Start with a mug that's much larger than the volume of cake batter. The cake will double in size as it cooks, and you don't want it spilling over the top of the mug.
Don't overmix the ingredients! It's fine if there are a few small lumps.
Garnish your keto Lemon Mug Cake with whipped cream and a bit of lemon zest.
Insert a toothpick or thin knife into the center of your mug cake to see if it is cooked. There should be a few clingy crumbs but no raw batter. If you see batter, give it another 10-15 seconds to cook.

**please note that the sugar alcohols from the sugar substitute are not calculated in this recipe because they have no calories and no carbs.
