  • 1 tablespoon melted butter
  • 2 tablespoons sugar
  • 3 tablespoons milk
  • 2 tablespoons + ½ teaspoon freshly squeezed lemon juice, divided
  • ¼ cup flour
  • ½ teaspoon baking soda
  • ⅛ teaspoon salt
  • 2 teaspoons lemon zest
  • 2 tablespoons confectioner sugar


  1. In a mug, combine the melted butter with sugar, stirring well.

  2. Add in the milk and 2 tablespoons of lemon juice to the mixture in the mug, stirring to incorporate.

  3. Stir in the flour, baking soda, and salt into the liquid mixture until well blended. Mix in the lemon zest.

  4. Microwave the mug on high for about 60-75 seconds, checking for doneness at the 60-second mark. The cake should be set and not wet in the middle when done; note that microwave cooking times may vary.

  5. For the glaze, whisk together the confectioner sugar and the remaining ½ teaspoon of lemon juice in a separate bowl. Adjust the sugar and lemon juice as needed for your desired consistency, then drizzle the glaze over the cooked mug cake.

The cake is ready to be enjoyed straight from the mug or turned out onto a plate. Experience the perfect solo dessert treat in an incredibly short time!
