I altered this recipe to our taste from the America’s Test Kitchen version via Renny Powell’s 1954 prize winning version at the 5th Pillsbury Bake-Off Contest. Renny had named the cake (a family recipe) based on the affect it had on teen-age boys. 🙂
Based on my family, daddy always added a pat of butter when reheating something like this that gives it little OOOMPH 🙂
