Preheat the oven to 425° Fareneheit. In a mixing bowl, sift together the flour, baking powder, soda and salt. Stir in the sugar. Using a stand mixer with a paddle attachment, cut in the butter until the mixture is crumbly.

In a seperate bowl, stir the Stonyfield Organic Grassfed Vanilla Yogurt with the egg. Mix until fully incoporated. Add to the flour mixture as well as the dried cranberries. Mix until just incorporated.

Lightly flour a surface and turn the dough out onto a lightly floured surface. Pat it into a rectangle at least one-half inch thick, using only the flour necessary to keep the dough from sticking to the surface. *The dough will be very soft--just make sure you have flour on your hands and work surface so it won't stick.

Dip a bench knife in flour and have a large baking sheet ready. Cut the dough in half, then cut each wedge 4 times. Using the bench knife lift the wedges carefully onto the greased baking sheet (or SILPAT).

To make the glaze, stir the yogurt and powdered sugar together. Brush half the the mixture over the scones. Bake the scones for 12-15 minutes or until lightly browned. Drizzle additional glaze on top and serve immediately.
