Mocha Glazed Chocolate Chip Hazelnut Scones are moist scones that pair beautifully with coffee. They're great for dessert, breakfast or any time.
Preheat oven to 400F and put baking rack in the middle of the oven. Line a large baking sheet with parchment paper.
In a large bowl, add flour, sugar, baking powder, and salt.
Grate the frozen butter on a cheese grater or in a food processor. Add grated butter to flour mixer and cut with a pastry knife or mix with fork and fingers. It should be coarse.
In a small bowl, stir together heavy cream, egg, and vanilla extract. Add to flour mixture and stir until well combined. Fold in the hazelnuts and chocolate chips. Dough will be a little wet. Form dough into a ball and flatten to about 8" diameter and place onto the cookie sheet on top of the parchment paper. Cut into 8 equal wedges. Bake 20-25 min.
Meanwhile, make the mocha glaze. In a small bowl, stir together the powdered sugar, half and half and instant espresso granules until smooth. Pour on top of the baked scones.
