This Sugar Cookie in a Mug recipe uses just a few simple ingredients and 'bakes' right in the microwave. The recipe makes one mug cookie so it's perfect for a single serving dessert. Mix in your favorite sprinkles for a festive, sweet treat!


  • 1 tablespoon unsalted butter
  • 2 tablespoons white granulated sugar
  • Small pinch of salt - omit if using salted butter
  • 1 egg yolk
  • 1/4 teaspoon vanilla extract
  • 3 tablespoons all-purpose flour
  • 1/2 - 1 teaspoon sprinkles. Optional.


  1. Melt Butter - In a mug, melt the butter in the microwave for about 30 seconds.
  2. Add Remaining Ingredients - Add the sugar to the melted butter and stir to combine. Add the egg yolk and vanilla extract - stir to combine. Then stir in the flour, salt, and sprinkles.
  3. Microwave - Microwave the mug until the cookie is rising and just set (40 seconds to 1 minutes). I like to start at 40 seconds and continue in 5 second intervals until done.
  4. Enjoy - Let cool a couple of minutes and enjoy! The mug cookie is best enjoyed right away, it will dry out faster than regular oven-baked cookies.


Mug Size - Any standard size coffee mug works! I used mugs that were at least 8 ounces to leave room for the cookie to puff up and rise while 'baking'. The most important piece is to use a mug that is microwave safe!
