Ingredients:
1 tablespoon butter, melted
1 tablespoon white sugar
1 packed tablespoon brown sugar
A few drops of vanilla
1 egg yolk
Slightly less than 1/4 cup of flour (level or lower)
Chocolate chips to taste (I'd go with about 1 heaping tablespoon for a normal cookie)
Directions:
Mix together butter, sugars, vanilla, and egg yolk in a microwave safe mug, then beat in flour. Stir in chips.
Microwave for about 45 seconds: check to see if the top is dry (a little dampness around the sides is fine)
Enjoy!
[Warning: Right after microwaving, the chocolate chips are hot as lava! You might want to let the cookie set for a few minutes before eating or risk a scorched tongue.]
