With your hands, shape into 20-ml (4 teaspoons) balls. Roll in the cinnamon sugar. Shake to remove any excess and place on the baking sheets, spacing them about 2.5-cm (1-inch) apart. Bake, one sheet at a time, for about 12 minutes or until lightly browned. Will keep for 3 to 4 days in an airtight container at room temperature.
