I'm not sure where this recipe originated; I've made it for my family for over 20 years. To me, it tastes like chocolate ice cream. Make it a mocha pound cake by adding 2 tablespoons instant coffee granules! Make the cake extra special by adding Recipe #387021. :) If Hershey's Special Dark dutch-processed cocoa is used, the cake will be a rich dark color! *Note: For a lighter, even more tender cake, separate the eggs; cream in the egg yolks with the butter and sugars; fold the stiffly beaten whites into the batter after the sour cream is added.
