5 Minute 3 Ingredient Microwave Nutella Brownies

Mug cakes have been all the rage in blog-land for a couple of years now so I'm a bit late to the table with this. Here's my recipe, for 3 ingredient Nutella Brownies which can be cooked in the microwave. They are immense - dense, rich and chewy, super-easy to make and ready in 5 minutes.

Nutella Brownies are of course fabulous on their own. However, they are extremely good topped with crème fraîche and fresh berries. Vanilla ice-cream is always a good accompaniment for warm brownies. Sometimes I add some chopped nuts to the mixture as well, or a pinch of hot chilli powder. Adding a pinch of salt to brownies makes them taste more chocolately, so I have included that in the recipe as well. 

You can avoid extra washing up by mixing and cooking the Nutella Brownie mixture in a mug, but I quite like to split the mixture into two, or even three, little ramekins or espresso mugs. The recipe makes enough mixture for two large or three regular-sized servings. 

A little word of advice about baking brownies in a microwave - be careful not to over bake them. Microwave times vary - I have a Panasonic Combi which cooks Nutella brownies, in two ramekins, in 1 minute. If they are not cooked through after 1 minute cook for 10 seconds at a time, checking them at each interval with a skewer. The brownie mixture will cook more quickly if it's split into two ramekins than if it's cooked in 1 mug.

  • Calories: 540 per serving


  • 125g nutella
  • 1 large egg
  • 30g plain flour

  1. Mix the nutella and the egg in a bowl or a mug until smooth. Add the flour and salt (if using) and stir until well combined.

  3. Microwave on full power for roughly 1 minute or until they are just firm and look set on the top. Use a sharp knife to check if they're cooked through (see notes above).

  4. Leave to cool before serving. Nutella brownies are so delicious topped with crème fraîche and fresh berries
