I found out after last week’s post that Mom Slabach had an “original” chocolate sheet cake that she used. The fact is that Aunt Peggy (her sister-in-law) had a chocolate sheet cake recipe and it was the one Mom used – at least some of the time. By the time I married into the family, the recipe I posted last week had made its debut in Mom’s kitchen, and it’s the one I remember her using. The recipes are a lot alike except this one uses buttermilk with baking soda instead of sour cream. It also uses water and shortening. The frosting recipes are identical.
Both recipes say to add the frosting while the cake is still hot. Some folks wait until the cake is cooled and then make the frosting. If you choose this option, you won’t need as much frosting, because the frosting won’t run down into the cake.
Both recipes are great and, because we are Slabachs, we have strong opinions about which one we think is the best. That means you get to vote and break the tie. Just kidding. I never really took a vote; I just know there is a disagreement on which is the best. The cake freezes well, so go ahead and try this recipe and save it for a rainy day.
My friend Allison, who is eleven, spent the day with me and helped me make this cake. Here she is pouring the batter into the jelly roll pan.
To make the frosting, bring the ingredients to a boil and then remove from heat. Add confectioners sugar and vanilla. Here is the start of the frosting, just when it is ready to begin boiling.
