Free Sweet Cinnamon Mug Cake Recipe

Mug Cakes can be very comforting at odd hours of the night. Especially when you’re just ending a long day, and feel that just a few bites of some yummy cake will do the trick.

I believe anyone who can’t do without sweet treats must add these recipes to their dessert repertoire.⁣

Today, I’m going to show you how to whip up a cinnamon mug cake in about 5 minutes.⁣

This Sweet Cinnamon Mug Cake is soft, fluffy, and moist and puffs up beautifully. Just a hint of the cream tartar enriches the sweetened batter with a slight tanginess, complimenting the warm cinnamon. It’s one of those sweetly spiced indulgences you have to have when the craving strikes.
