Preheat the oven to 180C (350F) and line a square baking tin with baking paper.

In a large bowl, whisk together the eggs and nutella until combined and smooth.

Fold in the flour, baking powder, chocolate chips and caramel fudge until just combined.

Pour into the baking tin and spread evenly. Bake for 22-26 minutes, or until a skewer inserted into the middle comes out almost clean.

Allow to cool completely in the pan and then cut into even squares.
