Preheat oven to 375°F.
Spread crescent roll triangles onto a baking sheet covered with parchment paper.
Crush the walnuts and mix them together with the raisins. Spread 8 oz. of cream cheese on the roll triangles, then thinly spread nutella over the top (if you are opting to use the spread), sprinkle with all of the nut/fruit mixture and most of the cinnamon sugar.
Gently roll each triangle up into a crescent shape, curling the ends slightly like a croissant.
Melt the butter and brush the outside of the rolls before baking, sprinkling a little more cinnamon sugar over them all.
Bake for 13-14 minutes or until golden brown.
