Tips and FAQ's
Can I make more than one?
This recipe is written for one chocolate chip cookie, but you can easily double it to make two!
You can either mix them up separately. Or mix up together and then divide cookie dough batter between two mugs. It’s best to microwave them separately, though.
What size of mug should I use?
Any standard size (8 ounces or larger) coffee mug works! The cookie will puff up slightly and rise as it bakes. The most important piece is to use a mug that is microwave safe!
Do I need to grease my mug?
Because you eat the cookie right out of the mug, you do not need to grease. Although, if you want easier clean up you could spray with cooking spray before mixing up and cooking.
I do not grease and instead just soak the mug in some warm soapy water for a few minutes before cleaning to remove any cooked on bits.
