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! 😉

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.
