Description

This vanilla donut mug cake delivers bakery-style sweetness in just 90 seconds using simple pantry ingredients. Perfect for satisfying sweet cravings without the mess or time commitment of traditional donut making.


Ingredients

Scale

4 tablespoons all-purpose flour

3 tablespoons granulated sugar

1/4 teaspoon baking powder

1/8 teaspoon salt

Pinch of nutmeg

3 tablespoons milk

2 tablespoons melted butter

1/4 teaspoon vanilla extract

For glaze:

1/4 cup powdered sugar

12 tablespoons milk

1/4 teaspoon vanilla extract


Instructions

1. In a microwave-safe mug (at least 12 oz), whisk together flour, sugar, baking powder, salt, and nutmeg until well combined.

2. Add milk, melted butter, and vanilla extract to the dry ingredients.

3. Stir until just combined – don’t overmix. Batter should be slightly lumpy.

4. Microwave for 60-90 seconds, checking at 60 seconds. Cake is done when a toothpick inserted in center comes out with few moist crumbs.

5. Let cool for 30 seconds.

6. For glaze: whisk powdered sugar, milk, and vanilla until smooth. Drizzle over warm cake.

7. Enjoy immediately while warm!


Notes

Microwave wattages vary – start with 60 seconds and add time as needed

Use room temperature ingredients for best results

Don’t overmix to avoid tough texture

Cake continues cooking from residual heat after microwaving

Store any leftover glaze in refrigerator for up to 1 week
