I was surprised that I had to add 12 eggs whites to the mix as "regular" angel cake mixes only call for the addition of water! So, be prepared if you plan on using a gf angel cake mix - don't foret to buy a dozen eggs too! Egg whites that come already separated in a carton are not recommended for baking.
Our gluten-free angel food cake wasn't quite as light and airy as a traditional angel food cake, but it look fabulous and tasted delicious! Most importantly, my food critic was thrilled and enjoyed every birthday bite.
