My love for sugar cookies developed during last year’s holiday season! Seriously, I hated sugar cookies because all I had tried were those store bought, stale, tasteless cookies and I wasn’t about that life.

This past December I decided that I was going to make my own Soft Sugar Cookies to see if I liked them or not and I absolutely fell in love. They’re one of the most delicious and comforting cookies out there… Especially if you top them with homemade vanilla frosting.

This is the best sugar cookie in a mug recipe ever!

Now that the holiday season is over, I can’t just keep making batches on batches of sugar cookies because I can’t use my regular excuse, “oh! I’m just making these to gift to friends and family”. Well I guess I could but they don’t want anymore as of right now, haha! They said I’m making them fat.

I wasn’t gonna let that stop me, I was still gonna get my sugar cookie fix. I just needed to make it in a smart way. And the smartest way to do that at the moment has to be a single serve microwave cookie! Again, I’m not mad at all.


This sugar cookie recipe will have a slightly different texture compared to your regular oven baked cookies. The taste though is the exact same. Yay!

How to make a sugar cookie in a mug?

  • Add in the granulated sugar and the brown sugar.
  • Mix in the egg white and vanilla extract
  • Add in the flour corn starch, and salt and mix until fully incorporated
  • Bake in the microwave and enjoy your quick personal cookie!

Does the size of the mug matter?

Yes and no. You need to make sure that you are microwaving your mug sugar cookie is a mug or bowl that’s big enough for it not to overflow. Since it will expand a little bit you will need to have a mug or a bowl that is about 1/3 or so empty before you bake this cookies.

I personally prefer using a little bowl so that I get more of a cookie feel. If you use a mug that is too thin and deep, you run the risk of having a cookie that is too close to a cake.

So as far as mugs go, use a large or regular sized mug that’s a bit wide to get a wider more traditional cookie. You can also use a little bowl for this sugar cookie!

Do I need to grease my mug?

You do not need to grease your mug. Since we melts the butter directly in the mug, that will coat the bottom. After baking or microwaving, you are also enjoying this straight out of the mug or bowl you baked your cookie in so no need to worry about anything sticking.

Tips to make the best microwave sugar cookie in a mug

Here are a few helpful tips that will ensure that your sugar cookie turns out as good as ours!

  • Don’t overcook your sugar cookie in the microwave– Follow the cooking instructions then test for doneness. If you feel your cookies needs to be baked for a little longer, bake in additional 10 seconds increments to avoid burning it.
  • It doesn’t have to be in a mug – This recipe calls for 50 second of baking in the microwave. Check for doneness then cook it for additional 10 second increments if you feel like it still needs more.
  • Mug cookies are best enjoyed right away! This is one of the most important tips I could give you. Mug cookies are best enjoyed right away, the longer they sit the harder they get so prepare this whenever you are ready to enjoy it.
