In a large mixing bowl, cream together sugar and solid white shortening until light and fuffy. Stir in dry milk solids and corn syrup. Add eggs, one at a time, beating well after each addition. In a separate bowl, sift together the cake flour, baking powder, and salt. Add dry ingredients to creamed mixture alternately with the water, beginning and ending with the dry ingredients. Stir in vanilla. Scoop out 1/3 cup of batter and place it on a greased and floured baking sheet. Smooth out to 3 1/2-inch circle. Batter will spread considerably so do not bake more than four on one cookie sheet at a time. Bake in 350F oven 18 minutes or until lightly browned. Cool on cake rack; frost half of cookie with chocolate fondant and half with vanilla. Hold cookie over bowl while frosting. Work quickly while fondant is warm.
