Preheat the oven to 400 degrees. Line a large baking sheet with parchment paper.

Whisk together the half-and-half, egg and vanilla bean paste.

In a large bowl, whisk together the flour, sugar, baking powder and salt. Add the cubes of butter and use a pastry cutter or two forks to cut the butter into the mixture until it resembles coarse crumbs.

Add the half-and-half mixture to the flour mixture and mix in until a soft dough forms.

Roll out on a lightly floured surface into a 9x13 rectangle, about ½ inch thick.

Cut into 4-5 inch long rectangles, the cut each rectangle on the diagonal, creating a triangle.

Place on the prepared baking sheet and bake for 8-10 minutes or until just golden brown.

Let cool while you prepare the glaze.

Whisk together the powdered sugar, half-and-half and vanilla bean paste into a thick glaze.

Place the scones on a wire rack on top of the baking sheet. Drizzle the glaze on top and allow to set.
