Line a baking sheet with wax paper, and place in freezer. Process espresso beans in a food processor 30 seconds or until finely chopped. Pour espresso crumbs into a shallow dish. Scoop ice cream into small balls using a 1 1/4-inch ice-cream scoop, and roll ice cream in espresso crumbs. Arrange on prepared baking sheet in freezer. Freeze 30 minutes to 24 hours. Serve in Dipped Sugar Cones, if desired.
Mini Nutty Ice-Cream Scoops: Substitute 1/2 cup finely chopped mixed nuts for chocolate-covered espresso beans and low-fat vanilla bean ice cream for coffee ice cream. (Do not process nuts.)
