My Best-Ever Vanilla Mug Cake recipe is the epitome of mug cakes — classic vanilla flavor, loads of sprinkles, and made entirely in less than 5 minutes.
In a microwavable mug whisk together the flour, sugar, and baking powder.
Add in the milk, oil, and vanilla and mix until just combined. Stir in the sprinkles.
Microwave for roughly 45 seconds - 1 minute, or until firm to the touch (timing is based on my microwave which is 1200 Watts so your timing may vary).
