Indulgent Nutella Mug Cake in Minutes

Gather the ingredients.

Combine 1/4 cup whole milk, 1/4 cup all-purpose flour, and 1/4 teaspoon baking powder in a 12-ounce microwave-safe mug. Whisk until smooth.

Add 1/4 cup Nutella and stir until the batter has no lumps.

Microwave on high for about 45 to 60 seconds.

Continue to microwave in 15-second intervals. Microwaves can vary, so check that the cake looks set and dry, feels springy and fluffy to the touch, and the edges are pulling away from the sides of the mug. This should take an additional 30 to 60 seconds in total. Serve immediately.
