After mixing it, I just put a small amount of butter in my cupcake pans, along with brown sugar, chopped pineapples, and cherries. I put them into the oven for a bit to melt the butter before putting in the cake mix.
When they were done, I let them cool for a minute, then turned them out onto a cookie sheet. And they came out great. I think I should put a little more crushed pineapple next time.
