Betty Crocker Cookie Icing is the easy way to decorate cookies. Simply squeeze the ready-to-use pouch over your cookies to create beautiful and delicious treats. The icing sets up quickly, so you can stack your cookies to transport or store them. No heating required! Directions: 1. Remove cap. Knead pouch for 1 minute. 2. For writing, snip the tip at the smallest notch. For flooding, snip the tip at the middle notch. 3. Squeeze icing onto cookies in desired pattern. Icing will flow to fill in the gaps. Icing begins to set after 4 minutes, wait approximately 4 hours before stacking cookies. Cool cookies completely before decorating. Do not refrigerate icing.
