Spread one side of 2 tortillas with 1/2 the cream cheese. Spread equal amounts jam over cream cheese. Spread remaining 2 tortillas with remaining cream cheese, and place on top of first 2 tortillas to form quesadillas.
Place quesadillas in a skillet sprayed with cooking spray over medium heat and cook 5 minutes on each side, until golden brown. Serve sprinkled with powdered sugar.
