Grab a large microwave-friendly mug and spoon some Nutella into the mug and pour in the milk.

Stir the ingredients using a fork or small whisk until they are combined.

Then, add all-purpose flour and baking powder directly into the wet ingredients.

Stir well until the batter is smooth and lump-free. Scrape the sides and bottom to fully mix all the ingredients.

Microwave the mug cake on high for 1-1.5 minutes. You will know it’s done when it’s puffed up and dry to the touch.

Let the cake rest for a few minutes to firm up and cool slightly.

Dig into the creamy, chocolatey Nutella mug cake and savor every mouthful!
