["1. Preheat the oven to 375 degrees. Line 2 half sheet pans with parchment paper.", "2. MAKE THE BISCUIT DOUGH: In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda and salt.", "3. Using a pastry blender, cut in the butter until coarse crumbs form.", "4. Make a well in the middle of the flour mixture. Add the half and half and vanilla extract with a wooden spoon or spatula and stir just until dough comes together.", "5. Turn the dough out on a lightly floured surface. Gently gather any loose crumbs into the dough mixture and fold over JUST a few turns forming into a ball.", "6. Roll the dough into a 1/2"" thick rectangle on a lightly floured surface. Use more flour if necessary on the board and your hands to keep dough from sticking. Keep the dough cold!", "7. MAKE THE FILLING: In a medium bowl, toss together the pecans and mini chocolate chips.", "8. PUT IT ALL TOGETHER: Spread the middle of the dough with the Nutella and sprinkle with the pecan/chocolate chip mixture evenly. Leave the top and bottom of the dough with no filling at least 2 inches from each edge. Roll up in a log, starting from the long side. Pinch the seam to seal in the filling. Roll the log to form an evenly round log shape. With a sharp floured knife, cut the dough into twelve 1-inch thick slices, flatten slightly with the palm of your hand and then dip in sugar. Arrange 6 to each cookie sheet. Bake for 10-15 minutes or until light golden brown. Cool to firm up before serving."]
