This Sugar Cookie Mug recipe uses just a few simple ingredients and cooks in a mug 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
  • 1/21 teaspoon sprinkles. Optional.


  1. In a microwaveable mug, add the butter and microwave to melt (about 30 seconds).
  2. Add the sugar to the melted butter and stir to combine.
  3. Add the egg yolk and vanilla extract – stir to combine.
  4. Stir in the flour, salt, and sprinkles until combined.
  5. Microwave the mug for 40 seconds to 1 minute until the cookie is risen and is just set. I like to start at 40 seconds and continue in 5 second intervals until done.
  6. 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.
