Preheat the oven to 350 degrees F. Separate the biscuits. Dust a work surface with flour and roll each biscuit round into a 6-inch circle (about 1/16 inch thickness). Place 2 teaspoons cream cheese and 2 teaspoons jam on one side of the dough round. Brush the outer edge of the pastry round with egg wash. Fold one side over the filling and crimp the edges with the tines of a fork. Place on the prepared baking sheet.
Brush the entire pastry with the egg wash and sprinkle with coarse sugar. Cut a slit in the top of each pie to allow steam to escape as they bake. Repeat the process with the remaining biscuits. Bake until golden brown, about 16 minutes. Serve warm.
