Preheat oven to 350F degrees. Line a baking sheet with parchment paper or a nonstick baking mat and set aside.
Open cans of dough and slice into 3 pieces each. Spread optional flour onto a flat surface.
Roll out each piece to about 1/4 inch thickness. Spread about 1 1/2 tablespoons of nutella on top and pinch into a ball.
Roll each ball out to an oval shape. Using a sharp knife, make widthwise incisions across about 1/2-inch apart on each piece.
Turn pieces over and roll up lengthwise. Shape into a crescent and pinch ends together with beaten egg. Brush tops with egg.
Place breads onto prepared baking sheet and bake for 20-25 minutes until golden. Enjoy hot, warm or cold!
