Get your Nutella HERE
Add the chocolate to a heat safe bowl and melt over a double boiler while stirring until smooth.
Fold in the Nutella until completely incorporated, and then the nuts.
Turn the chocolate mixture into a parchment lined 9x5 inch loaf pan and spread out evenly. I give the pan a few sharp raps on the counter to settle all the chocolate.
Let sit until completely hardened. I left mine overnight at room temperature, to speed things up you can also pop it in the fridge.
Use the parchment paper to lift out the fudge. Slice it into 2 inch chunks.
