Sugar Cookie In a Mug is a quick and easy warm sugar cookie, made in minutes, in a mug in the microwave! Make this mug cookie when you are craving something sweet, but do not want to make a full batch of cookies.

What Are Mug Cookies?
Mug cookies are literally that, a cookie cooked inside of a coffee mug. This is a perfect example of recipe scaling to fit your needs. Sometimes you double or triple a cookie recipe so that there is enough for a party or gathering. But sometimes it is just you curling up on the couch after the kids go to bed and you want something sweet. This mug cookie is a perfect single serving dessert for those nights or for a fun evening with the kids too. Have everyone make their own microwave sugar cookie and decorate the top with sprinkles, colored sugars, or whatever else add-ins might be desired (chocolate chips are always a hit!)

Mug Sugar Cookie Ingredients
Butter: Use 1 tablespoon of butter to help add a nice rich taste and texture to the mug cookie.
Sugar: Adding in 2 tablespoons of granulated sugar will help our cookie to turn out nice and sweet.
Vanilla extract: For a great tasting treat, adding in 1/4 teaspoon of vanilla extract will help to do just that.
Salt: Add in a pinch of salt to help enhance the flavors in this cookie and really make it taste incredible.
Egg: You will need to use 1 egg yolk to help bind the dough together and create a nice cookie texture. Egg yolks are what make baked goods, like cookies, taste incredible.
Flour: You need 3 tablespoons of all-purpose flour to be the base and structure of the dough.
Sprinkles: If desired, you can use fun and colorful sprinkles to garnish your cookie with before baking.
How to make a Sugar Cookie in a Mug
How do I know when my mug cookie is done cooking?
You will know that your mug cookie has finished baking when the time has elapsed and the cookies are puffed up within your coffee mug. Not only will the cookie look puffy, but the edges should appear to be set and dry while the center may look a little softer or glossy as well. If you are still unsure if the cookie has finished baking properly, you can check it with an instant-read thermometer, it should reach 165 degrees F.
What size coffee mug do I need?
A standard 12-ounce coffee mug is almost always recommended and a 10 ounce one usually works well too. You will have to trial and error test anything smaller than that (like a cappuccino mug) because sometimes they work and other times they puff up and over the mug sides as they are all slightly different in size, width, and depth, which leads to different results with each mug.

Follow the recipe!!! I didn’t feel like separating an egg, so I used a whole one and it came out so rubbery and spongey! Definitely worth the 10 extra seconds to separate the egg.
