Chocolate Oreo Cookie Cake
Beat Parkay margarine and sugar until creamy. Add eggs, vanilla, salt, and cocoa. Mix baking soda in buttermilk until it starts to fizz. Pour buttermilk into batter. Stop mixer and add flour. Mix until smooth, about 3 minutes. Add boiling water and mix.
In a Ziploc bag, coarsely crush Oreo cookies until you have enough for 1 cup, taking out 3 TBSP of crushed Oreo cookies to use later in the frosting. Stir the rest of the 1 cup crushed Oreo cookies into the cake batter. Pour batter into long cake pan 13 x 9 x 2. Bake at 375 degrees for 35 minutes. Test if it's done using a toothpick. If toothpick comes out clean, it's done. If it doesn't come out clean, leave in a few more minutes and retest.
Feed in mixer 1/2 box Domino's Powdered Sugar (1 lb. size), 1 stick Parkay margarine, 2 tsp. imitation vanilla, and 1 1/2 TBSP milk. The longer you beat it the creamier it gets. When finished making frosting, stir in the 3 TBSP of crushed Oreos that you had set aside.
Frost cake when it is cool. You can add more crushed Oreos to the top for decoration if you wish.
