Roll each slice into a ball, then roll in sugar and place each ball into a muffin cup.
Bake at 350 degrees for 15 minutes.
Remove from oven; press down the center of each cookie cup gently to make a small indentation.
Fill each with 1 tablespoon cherry pie filling.
Return to oven and bake an additional 3-5 minutes.
Cool slightly; remove from pans.
