VANILLA-FROSTED FUDGE COOKIES

3/4 c flour
1/2 c unsweetened cocoa powder
1 ts baking powder
1/4 ts salt
1/4 c canola oil
1 c sugar
1 1/2 ts vanilla extract
4 egg whites -- unbeaten
2 c confectioner's sugar
2 T to 3 T skim milk -- approx.
unsweetened cocoa powder --for dusting

Preheat oven to 350°. Spray a large nonstick cookie sheet with vegetable oil spray. Sift the flour, cocoa, baking powder and salt together. Set aside. Mix together the oil, sugar, 1 tsp. vanilla and the egg whites until well combined. Stir in the flour mixture. Chill for one hour. Using a 1/2 Tbsp. measure, scoop the dough onto the cookie sheet, leaving 2 inches between cookies. Bake for 8-10 minutes or until the cookies are puffed and cooked through. Do not overcook. Transfer the cookies to a rack and cool completely. Mix together the confectioners' sugar, skim milk and remaining 1/2 tsp. vanilla unsil pasty. Add skim milk if necessary. Spread a small amount of vanilla frosting on each cookie. Put the cookies back on the rack, dust lightly with cocoa powder and allow the frosting to dry.
