Start by lining a 9x9 inch baking dish with parchment paper.
In a microwave-safe bowl, add the 2 cups of chocolate chips. Microwave in 30-second intervals, stirring in between, until fully melted and smooth.
Once melted, add the 1 cup of Nutella and mix until completely blended and smooth.
Pour the mixture into the prepared baking dish and spread it evenly.
Place the dish in the refrigerator for at least 2 hours until the fudge has set.
Lift the fudge out of the dish using the parchment paper, cut into squares, and serve.
