20 Nilla Wafers, finely crushed
1/2 cup flour
1/4 cup firmly packed brown sugar
1/4 cup (1/2 stick) cold butter
1 pkg. (8 oz.) Neufchatel Cheese (I use cream cheese)
1 cup granulated sugar
2 Tbsp. flour
3 Tbsp. grated lemon peel, divided
1/4 cup fresh lemon juice
1/4 tsp. Baking Powder
2 tsp. powdered sugar
PREHEAT oven to 350ºF. Line 8-inch square baking pan with foil, with ends of foil extending over sides of pan; set aside. Combine wafer crumbs, 1/2 cup flour and the brown sugar in medium bowl. Cut in margarine with pastry blender or two knives until mixture resembles coarse crumbs; press firmly onto bottom of prepared pan. Bake 15 min.
MEANWHILE, beat Neufchatel cheese and granulated sugar with electric mixer on medium speed until well blended. Add eggs and 2 Tbsp. flour; mix well. Blend in 1 Tbsp. lemon peel, lemon juice and baking powder; pour over crust.
BAKE 25 to 28 min. or until center is set. Cool completely. Cover and refrigerate at least 2 hours or overnight. Sprinkle with powdered sugar and remaining 2 Tbsp. grated lemon peel just before cutting into squares to serve. Store leftover squares in refrigerator.
