Preheat the oven to 170C Fan. Grease and line a 20x30cm baking tin with baking paper.

Add the Nutella and the eggs into a large mixing bowl and use a whisk to beat until smooth.

Use a sieve to sift in the flour and cocoa, then use a spatula or large spoon to fold it through until it’s well combined.

Chuck in the chocolate chips and mix them in then spoon the brownie mix into the lined baking tin, then spread it into the edges.

Bake it for 20 minutes. Then take it out and leave to cool completely.

Once cooled, cut it into portions and enjoy.
