A few websites that offer a crushed pineapple cake recipe are Dole, What's Cooking America and Martha Stewart. The Dole site has a pineapple poke Bundt cake recipe that is easy to make because many of the ingredients are items such as yellow cake mix, a can of crushed pineapple and instant vanilla pudding.
These ingredients along with eggs, vanilla and oil are mixed together, placed into the Bundt pan and baked for 40 minutes. The cake is then drizzled with a glaze. The What's Cooking America website has a crushed pineapple and carrot recipe with a cream cheese frosting. The instructions for this recipe are detailed and easy to follow.
Martha Stewart's site contains a loaf cake made with crushed pineapples and shredded coconut. The cake contain other simple ingredients and takes about 1 hour and 25 minutes to make.
