This is sort of a compilation of recipes I’ve seen and tweaked. Its very pineapple-y. You could probably add coconut to it too and it would be good.
1 box DH yellow cake mix 1/2 cup pineapple juice frozen concentrate 1/2 cup water 1/4 cup veg oil 1/2 cup crushed pineapples 3 eggs
Mix everything together and bake at 350 in greased pans until done. I made about 30 cupcakes with this recipe as is.
