Description

Quick and easy cinnamon sugar donut mug cake ready in just 2 minutes! This microwave dessert combines simple pantry ingredients to create a fluffy, sweet treat with all the flavors of a classic cinnamon sugar donut.


Ingredients

Scale

1/2 cup all-purpose flour

1/4 cup granulated sugar

1/2 teaspoon baking powder

1/4 teaspoon salt

Pinch of ground cinnamon

1 tablespoon milk

1 tablespoon melted butter

1 large egg

1/2 teaspoon vanilla extract

2 tablespoons cinnamon sugar (for topping)


Instructions

1. Mix wet ingredients: In a small bowl, whisk together milk, melted butter, egg, and vanilla extract until smooth

2. Combine dry ingredients: In another bowl, mix flour, sugar, baking powder, salt, and cinnamon

3. Create batter: Pour wet ingredients into dry ingredients and mix until just combined (don’t overmix)

4. Microwave magic: Pour batter into a microwave-safe mug and cook on high for 1-2 minutes

5. Add topping: Let cool for 1 minute, then sprinkle with cinnamon sugar while still warm

6. Enjoy: Serve immediately while warm and fluffy


Notes

Cooking time may vary by microwave – start with 1 minute and add 15-second intervals if needed

Don’t overmix the batter to keep the cake light and fluffy

For extra indulgence, add a drizzle of glaze or dollop of whipped cream

Store leftovers covered at room temperature for up to 1 day
