The original recipe I wanted to use had three eggs and some oil. I only had one egg, and I wanted to use it to make a half-batch of banana bread. So I figured I'd replace all of the eggs with applesauce. Then wait—people use applesauce to replace oil in recipes, too. Screw it! I'm replacing everything other than the cake mix with applesauce.
I wanted to make an apple spice cake to make cake balls out of (post forthcoming, if they turn out). Recently, I did this with pumpkin and was pleased with the results. So, this apple version? HEAVEN. Just ... wow. So moist, so delicious. I wanted to just eat it all straight out of the pan with a fork. It doesn't need frosting or anything.
You don't need a recipe, really. A child could make this by himself or herself. Mix these two ingredients (1 box spice cake mix, 1 jar apple sauce) together. Spread into a 9x13 glass pan. Bake at 350 degrees for about half an hour, until a fork comes out almost clean.
This could be portioned out as cupcakes, frosted or not frosted. It'll be one of my new go-tos!
