Ingredients

Dry Ingredients

  • ¼ cup all-purpose flour
  • ½ tablespoon cornstarch
  • ½ teaspoon baking powder
  • 3 tablespoons granulated sugar

Wet Ingredients

  • 2 tablespoons salted butter
  • 1 teaspoon vanilla extract
  • 3 tablespoons milk

Optional

  • ½ teaspoon sprinkles

Instructions

  1. Combine Dry Ingredients: In a small bowl, mix together the all-purpose flour, cornstarch, and baking powder until evenly combined.
  2. Melt Butter: Place 2 tablespoons of salted butter in a large microwave-safe mug and microwave for about 20 seconds or until fully melted.
  3. Add Sugar, Vanilla, and Milk: Stir the granulated sugar, vanilla extract, and milk into the melted butter until well incorporated.
  4. Form Batter: Add the dry flour mixture into the mug and stir thoroughly to form a smooth batter. If desired, gently fold in sprinkles for added color and texture.
  5. Cook in Microwave: Microwave the mug on high for 1 to 2 minutes. The cake should rise and appear puffy yet shiny on top, indicating it’s cooked through.
  6. Rest: Let the cake rest for 2 to 3 minutes; it will continue to cook and set during this time, ensuring a perfect texture.

Notes

  • Cooking time may vary depending on microwave wattage; start checking at 1 minute.
  • Use a large enough mug to prevent overflow as the batter rises during cooking.
  • For a dairy-free version, substitute butter and milk with plant-based alternatives.
  • Sprinkles are optional but add a fun visual and slight texture contrast.
