Honestly, the most moist, melt-in-your-mouth, to-die-for Texas sheet cake in the world. Kandi has this one perfected! Definitely one of my childhood favorites!
 Best Chocolate Cake in the World
Best Chocolate Cake in the World
Bring to a boil: 1 stick margarine, 7 Tbsp baking cocoa powder (equivalent to 3 squares baking chocolate) and 1 cup water. Remove from heat. Add this to 2 cups sugar and 2 cups flour. Beat well. Add 2 beaten eggs, 1 tsp vanilla, 1/2 cup buttermilk, 1/2 tsp salt and 1 tsp soda. 
Pour into a greased jelly roll pan (15 1/2 X 10 X 1) Pan size is important. The batter will be thin. Bake for 20 minutes at 400 degrees. Put on the following frosting while the cake is still hot. 
Frosting:
Bring to a rolling boil: 1 stick margarine, 4 Tbsp cocoa powder and 6 Tbsp milk. Remove from heat. Add 3 1/2 cups powdered sugar and 1 tsp vanilla. Mix well. One cup nuts may be added if desired. (Kandi makes it without nuts...) Pour over cake. The frosting is thin.
Note: The combination of the hot cake and the thin frosting makes it so the frosting drips off the sides. I will admit that as kids (okay, and as adults...) we would stand by and help "clean up" the frosting that was dripping. Before serving, Kandi takes a warm dish cloth and wipes around the edges.
