3 Ingredient Cinnamon Roll Mug Cake – Quick & Cozy

This 3 ingredient cinnamon roll mug cake is a quick, cozy, single-serve dessert made with self-rising flour, milk, and cinnamon sugar ready in just 2 minutes.

  • Total Time: 2 minutes
  • Yield: 1 mug cake

Ingredients

Scale

1/4 cup self-rising flour or pancake mix
1/4 cup milk (dairy or plant-based)
1 tablespoon cinnamon sugar

Instructions

Spray a microwave-safe mug with nonstick spray.
Add self-rising flour and milk to the mug.
Stir until the mixture is fully combined and smooth.
Sprinkle cinnamon sugar evenly over the top of the batter.
Use a toothpick or knife to gently swirl the sugar into the batter without fully mixing.
Microwave for 45–60 seconds, depending on your microwave’s wattage.
Allow to rest for 30 seconds before serving.
Enjoy warm directly from the mug.

Notes

Use any milk you prefer — oat, almond, or regular.
For added richness, add a teaspoon of butter or drizzle with glaze.
Let it sit briefly after microwaving to finish setting internally.
For homemade self-rising flour, mix 1/4 cup all-purpose flour with 1/2 tsp baking powder and a pinch of salt.
