Method
- Add flour, sugar, baking powder, and salt to a mug and stir together.
- Stir in milk, melted butter, and vanilla extract until smooth, being sure to scrape the bottom of the mug. Then stir in sprinkles.
- Then microwave for 70-80 seconds (until cake is just set, but still barely shiny on top). Allow to rest in microwave for 1 minute before consuming.
