2/3 cup MIRACLE WHIP Dressing
1 pkg. (2-layer size) yellow cake mix
2 tsp. grated lemon zest
2/3 cup ready-to-spread vanilla frosting
4 tsp. fresh lemon juice
Preheat oven to 375°F. Beat dressing, cake mix and eggs in large bowl with electic mixer on low speed just until moistened. Add lemon zest. Beat on medium speed 2 minutes. (Dough will be stiff.)
Drop rounded teaspoonfuls of dough, 2 inches apart, onto greased baking sheets.
Bake 9 to 11 minutes or until lightly browned. (Cookies will still appear soft.) Cool 1 minute; remove from baking sheets to wire racks. Cool completely. Mix frosting and juice until well blended; spread onto cookies.
