Chocolate Chip Cookie in a Mug

I am so fond of Mug Cakes...Chocolate Cake in a Mug, Red Velvet Cake in a Mug, and the like. But here's a new favorite that will haunt you.. and one that will satisfy that late night chocolate chip cookie craving. As with all the "Mug" recipes, you need to be precise or it will be too dry or too wet...or just awful. This Chocolate Chip Cookie in a Mug is so quick. 5 minutes to prep and less than a minute to cook! And, you'll find you have all the ingredients in your pantry. Perfect for that moment when you just want one cookie!

Chocolate Chip Cookie in a Mug

Ingredients 
1 Tbsp Butter
1 Tbsp White Sugar
1 Tbsp firmly packed Dark Brown Sugar
1/8 tsp Madagascar Vanilla Extract
Pinch of Kosher Salt
1 Egg Yolk (room temp)
3 Tbsp All Purpose Flour
2 Tbsp Semi Sweet Chocolate Chips

Directions
Choose a microwave-safe mug. It doesn't have to be tall. This is a cookie not a mug cake. You can even use a ramekin.
Put butter in mug and melt in microwave. Do not boil. Add sugars, vanilla, and salt. Stir to combine. Add yolk to cup. Stir to combine. Add flour and stir. (if too runny add a pinch more flour-think cookie dough) Add chocolate chips, and give a final stir.
Cook in microwave 30-50 seconds, start checking at 30 seconds but do not cook longer than 50 seconds. Cookie continues to cook after you take it out. Less time will produce a moister better cookie.
