Ingredients 3 cups sliced peaches (about 5) ¾ cup raspberries 2 tablespoons light brown sugar 4 ½ tablespoons plus ½ teaspoon granulated sugar 2 teaspoons cornstarch ⅛ teaspoon cinnamon ¾ cup all-purpose flour ½ teaspoon baking powder ¼ teaspoon baking soda Pinch of kosher salt 2 tablespoons chilled unsalted butter, cut into pieces 2 ½ tablespoons plain nonfat yogurt 2 tablespoons skim milk ¼ teaspoon pure vanilla extract Directions Preheat the oven to 400 degrees. In a 9-inch pie pan, stir together the fruit, brown sugar, 2 tablespoons granulated sugar, the cornstarch, and cinnamon. In a bowl, stir together the flour, 2 1/2 tablespoons granulated sugar, the baking powder, baking soda, and salt. With a fork, blend in the butter until the mixture resembles coarse crumbs. In a small bowl, whisk together the yogurt, milk, and vanilla and stir into the flour mixture until just combined. Knead the dough lightly on a work surface and pat lightly until it is about 3/4 inch thick. Drop the dough in 4 mounds over the fruit, sprinkle the remaining 1/2 teaspoon sugar over the dough, and bake in the middle of the oven until the biscuits are golden and cooked through, about 20 to 25 minutes.
