Many people would say that you cannot make truly good food in the microwave; you need to use a stove or an oven for great results. However, these cookies, which can be made in a mug and baked in the microwave within only one minute, are proof that this is not the case.
For this cookie, all you need is 2 tablespoons of chocolate chips, 1 tablespoon of peanut butter, 1 tablespoon of butter at room temperature, 1 egg yolk, 1 tablespoon of white sugar, 1 tablespoon of brown sugar, 1/4 cup of rolled oats, and 3 tablespoons of all-purpose flour.
First, mix the sugars and butter in a microwaveable mug. Once these are well combined, add in the egg yolk, chocolate chips, rolled oats, and peanut butter, and mix everything well. Add the flour, and then mix all ingredients completely. Put the mug into the microwave for 40 to 60 seconds (check to see if it is done after 40 seconds; it may vary a bit because all microwaves are different). Do not overcook it, or else it will become too dry.
Take your chocolate chip, oatmeal, and peanut butter mug cookie out of the microwave, and let it cool off a bit. However, do not let it cool too much, as these cookies are best served warm. Add the topping of your choice, get a spoon, and enjoy your cookie! You can certainly experiment with other cookie flavors as well, and find your favorite one to enjoy!
