Need Help -- Updating 'the family' birthday cake recipe.
This recipe is from the early 20th century and needs a bit of updating. There isn't enough of a chocolate punch, but with only vinegar and baking soda for leavening, I'm worried about throwing the balance off, especially if I add cocoa powder. To really complicate the issues -- I'm living at just high enough of an altitude -- 3,000 feet -- that affects most baked goods. FYI -- The original recipe used "sour top milk" and Spry, instead of butter. (If memory serves, Spry was a Crisco competitor.)
Happily, the caramel/walnut frosting that traditionally goes with the cake works just fine, 100 years later. Suggestions?
