I found this recipe awhile ago and have used it for so many cake decorating projects that I kind of know it by heart. Everyone loves it and it's easy enough for me to work with and stable to decorate on and stack.
Cake mix (I've used different brands and flavors)
1 1/3 cup
regular full-fat sour cream
egg whites (from carton, depending on how think you want. I've used 3/4 cup before and didn't notice a difference)
Combine dry ingredients in mixing bowl and mix until well combined. Add wet ingredients and mix until well incorporated. I normally mix it on high a little to get some air into the batter and to make it nice and fluffy with the egg whites. Pour into pans sprayed with cooking spray. I bake at 350 for 20 minutes for cupcakes and start at 25 minutes for any other cakes and add time as needed. Cool completely before taking out of pan. Sometimes I forget the salt or vanilla and don't really notice a difference so I just put it in if I remember. I've also tried different brands of cake mix and don't really like one over the other so I just use what is on sale or what I have on hand. Everyone loves this! What I love about this recipe is that for me, it always bakes up even on top so I don't have to level off my cakes before using them- saves time!
