Step 1

Heat oven to 350°F. Line 13x9-inch pan with foil, leaving foil overhanging at 2 opposite sides of pan; spray with cooking spray.

Step 2

In large bowl, mix cookie mix, softened butter, cream cheese and egg with spoon until soft dough forms. Spread dough in bottom of pan. Bake 19 to 23 minutes or until golden brown. Cool completely on cooling rack, about 1 hour.

Step 3

Remove bars from pan by lifting foil; peel foil away. Spread frosting over top. Cut into 27 triangles as follows: Using sharp knife, cut into 3 horizontal rows. Cut each row into 9 triangles so each triangle has about a 2-inch wide base, cleaning knife with paper towel after each cut to keep frosting clean of crumbs. (See link below for diagram.) Set aside end pieces for snacking.

Step 4

For each reindeer: Press 2 halved pretzels on top corners of cookie triangle for antlers, 2 candy eyeballs in center for eyes, 1 brown candy on tip of triangle for nose (use photo as guide). Repeat with remaining cookie triangles. Store covered in airtight container in single layer.
