Not that anyone should feel guilty for treating themselves. For me, it’s more about avoiding the full body meltdown after I eat sugar. Only a slight exaggeration!

Vanilla Mug Treat Recipe Tips & FAQ
How to mix the mug cake properly.
Do not over mix. Combine the ingredients so they are well incorporated. There is no need to keep mixing after the ingredients are combined.
Don’t let the cake batter sit too long.
Do not let the batter sit for too long. Coconut flour absorbs moisture and will keep doing so the longer it sits. The beauty of a 5-minute mug cake is to make it quickly, so do that! 😉
Watch out for that hot fork!
Hot poker alert! If you let the fork sit in the mug cake too long while it’s hot, the fork turns into a branding iron. Yes, I’ve clearly done this way too many times! Always test the temperature before you dig in.
