Pineapple upside down cake is an all-American tradition, thanks to the Dole pineapple company, which is largely credited with coming up with the original recipe. Since then there have been many variations on the upside down cake theme using other fruits, from apples and cranberries to mango and pear, just to name a few. But pineapple upside down cake remains the true classic and many people's favorite all around cake, hands down.
