Martha's Texas Sheet Cake

Martha's Texas Sheet Cake

Beat in bowl:
2 eggs
1/2 c. buttermilk (I use 1 1/2 t. vinegar and rest milk to make 1/2 cup)
1 T. vinegar
1 t. baking soda
1 t. vanilla

Add to this-
2 cups sugar
2 cups flour (sifted)
1/2 t. salt

Put this aside for now.

Bring to a boil:
2 sticks butter
1 cup water
4 T cocoa

Once this mixture is boiling, remove from the stove, and add to the other ingredients you mixed in the bowl. Mix all of it.

Place in a 11x17 greased cookie sheet. These are very hard to find because they are a longer size, but Michaels, Kitchen Collection, and Wal-Mart often carry them. I wouldn't recommend trying to make this in two smaller pans. It just doesn't work out well.

Bake 375 for 15 min (sometimes a minute or so longer).

Frosting (cook while the cake is baking)

Heat
1 stick butter
4 T cocoa
6 T milk

Remove from stove and add
1 box of confectioner sugar (sifted)
1 t. vanilla

Mix until smooth. Pour onto the cake after you get it out of the oven/while it is still warm. Let it sit out, and the frosting will harden.
