Wrap each roll in 1 piece of waxed paper or plastic wrap. Place in a freezer container with a tight-fitting lid or wrap airtight in a piece of foil. Label and date. Store in freezer.

Bake 10 to 12 minutes until edges are light brown and centers are slightly set. Cool about 2 minutes on baking sheet. Remove cookies and cool on wire racks.
