I haven't baked any kind of cake lately, so I can't address your specific question. Here's a little trick I learned years ago to make my cakes a little higher & lighter. I do this for both box & scratch cakes. Separate the eggs & stir in the yolks into the batter. In a separate bowl, whip the whites to soft peak stage, then gently fold them into the batter. Whipping the whites puts more air into the mixture. I can't guarantee you'll get the results you want, but you've got nothing to lose by trying.
