Place the oats in a food processor and blend until finely ground. Combine oats, cheese, butter, and xylitol in a mixing bowl. Using a fork, mix thoroughly until a firm, cohesive mixture forms.

Form the mixture into small balls and arrange them on a baking sheet. Insert a toothpick into the center of each ball. Place the baking sheet in the freezer and freeze for several hours or overnight.

Once the balls are firm, melt the sugar-free chocolate. Carefully dip each ball into melted chocolate, allowing any excess to drip off.

Refrigerate until ready to serve. These cheese balls can be frozen.
