Found these on cooks.com. They taste a bit like Oreo cookies, the filling tastes a lot like the Oreo filling but doesn't have quite the same texture. HOMEMADE OREOS 1 (18 oz.) pkg. Devil's food cake mix (I used a regular chocolate cake mix) 2 eggs, plus 2 tbsp. water 2 tbsp. cooking oil 1/2 c. cocoa Blend well until you can shape dough into ball. Let stand for 20 minutes. Form dough into half inch balls and place 2 inches apart on greased cookie sheet. Flatten each ball with the smooth greased bottom of a drinking glass or use your hands. Bake at 350 degrees for 8 minutes. Remove cookies at once and immediately flatten with the back of a spatula. Let cool for 20 minutes. FILLING: 1 env. Knox unflavored gelatin 1/4 c. cold water 1 c. Crisco 1 lb. plus 1 c. powdered sugar 1 tsp. vanilla Soften gelatin in 1/4 cup cold water. Place gelatin in a heat proof cup. Then place the heat proof cup in a pan of hot water until the gelatin becomes clear. Meanwhile, beat the Crisco until light and fluffy, adding sugar and vanilla. Beat well. Cool the gelatin and beat into filling. The gelatin is used only to keep the filling in place when spread in cookie. These freeze well. HELPFUL HINTS: I usually cut filling in half using the following: 1/2 c. Crisco 2 1/2 c. sugar 1/2 tsp. vanilla and 1/8 cup of the gelatin/water mixture.
