We’ve discussed this cake on its frosting card. Check out the card for chocolate lightning icing for a (brief) discussion of the name.
I mean, c’mon, you’re going over there anyway to frost this cake, am I right?
From a box sold in Canby, Oregon.
Lightning Chocolate Cake
1-1/2 cups flour
1 cup sugar
1/2 cup ground chocolate
1-1/2 teaspoon soda
1 cup sour milk or buttermilk
1/3 cup melted butter or fat
Sift together flour, sugar, chocolate and baking powder. Add milk, egg, and melted butter, beating well. 2 layers. (Medium oven.) 20 min.
Yesterdish suggestion: In this context, I think medium oven is supposed to mean 375 deg. F.
