In a small mug/cup/ramekin (I used an espresso mug), mix together all your ingredients except the chocolate chips, until you get sticky cookie dough batter.
** This cookie won’t rise much, so you probably don’t want your mug/cup to be too big. Although I guess you could double or triple the ingredients for more cookie volume!
Stir in chocolate chips.
Place your mug in the microwave and cook on high for 1 to 1-1/2 minutes.
** I suggest doing this in 30 second intervals so you can check on the cookie. If it still looks kind of wet/doughy on top, leave it in the microwave for a little longer. You shouldn’t need more than 1-1/2 minutes though — chocolate chip cookies are supposed to be gooey in the middle!
Allow mug and cookie to cool for a little bit, then dig in!
