G.G.'s Chocolate Sheet Cake Recipe

Directions

Preheat an oven to 350 degrees F (175 degrees C). Grease an 11x17 jelly roll pan.
Mix white sugar and flour in a large bowl. Combine 1 cup butter, water, and 3 tablespoons cocoa powder in a small saucepan; stir over medium heat until butter is melted and mixture is well combined. Pour melted butter mixture over sugar and flour; beat well. Beat in baking soda, buttermilk, eggs, and vanilla extract. Pour batter into prepared pan.
Bake in preheated oven until a toothpick inserted into the center of cake comes out clean, 20 to 25 minutes. Remove from oven and allow to cool on a wire rack.
Combine remaining 1/2 cup butter, 3 tablespoons cocoa powder, and milk in a small saucepan; stir over medium heat until butter is melted and mixture is well combined. Beat powdered sugar into the butter mixture, mixing until frosting is smooth. Stir pecans into frosting and pour over cooled cake.

"I have been making this cake since I was about 10 years old, and I will be 46 next month! Everyone who has ever had this LOVES it! So moist and delicious. I add extra cocoa, usually about a half cup t..." See moreotal, and have even used the dark cocoa, that is really good. On my birthday I always want the "Mississippi Mud" version-(my mom's) when the cake comes out of the oven, (baked in 9x13 pan) spread a jar of marshmallow cream over it while it is still very warm. Then make the frosting with the nuts, and once the marshmallow has cooled very carefully spread the frosting over the marshmallow. Yes, very decadent- thats why I want it for my birthday! I have shared this recipe more than any other over the years- everyone enjoy!"

"I also have made this recipe for many years. Our recipe has half butter and half shortening in the cake. It always turns out great. I have baked it in a 9 x13 inch pan when that was what was availabl..." See moree and it is still good. I have added cinnamon to the cake or icing for a little different flavor. I have made it without nuts in the icing for people who don't like nuts and have made it half with nuts in the icing and half without ( just pour some icing on half the cake and add nuts to the remaining icing and spread on the other half). I have a friend who makes it with regular milk not buttermilk. It is a very forgiving cake. Since the cake is very moist I have never tried layers. I use the same saucepan for the icing I use for the cake. I have seen this named Sheath Cake, Texas Sheet Cake and 22 minute cake. Happy cooking!"
