Cinnamon Stuffed Scone

for the dough

1 1/2 cups all-purpose flour
2/3 cup whole wheat flour
1/3 cup packed brown sugar
2 tablespoons granulated sugar
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 teaspoon cinnamon
1/2 teaspoon cardamom
2/3 cup plain greek yogurt
1 egg white
3 tablespoons butter, melted
3 tablespoons milk (reserved for brushing)
coarse sugar (reserved for topping)

for the filling
1/3 cup granulated sugar
1/2 tablespoon cinnamon
1/2 tablespoon all-purpose flour
1 1/2 tablespoons butter, melted

for the glaze
1/3 cup powdered sugar
2 tablespoons milk

Directions
Preheat oven to 400 degrees. In a small mixing bowl, combine the filling ingredients to form a paste and set aside. In a large mixing bowl, prepare the dough by whisking together the flours, sugars, baking powder, baking soda, salt, cinnamon and cardamom. In a small bowl, stir the yogurt and melted butter together, then whisk the egg white in to completely combine. Add the yogurt mixture to the dry mixture and stir until dry and clumpy. Using your hands, knead dough for 1-2 minutes, or until it is consistent in texture. Divide dough in half. Prepare a baking sheet with parchment paper or a silicon baking mat. Form each half of the dough into a flat, circular disc, about 1-inch thick. Place one on the prepared baking sheet. Spread cinnamon filling evenly over the top of the first disc, then top it with the other. Mold the outer edges together with your fingers to prevent filling to spilling out. Using a sharp knife, cut the dough into eight even wedges, but do not remove them from the circle. (This will make cutting and serving easier after it has baked.) Brush the outside with milk, then generously sprinkle with coarse sugar. Bake for 14-18 minutes, or until golden brown. Remove from oven to cool. Prepare the glaze by mixing powdered sugar and milk together to create a thick, but pourable drizzle. While still warm, drizzle glaze over the top of the scones. Cut into pre-scored wedges and serve.
