Fresh cranberries for topping, optional (or you could put some in with the pineapple before baking)
Instructions
Spray a glass 2-cup Pyrex bowl or other small oven-safe bowl with nonstick cooking spray. Place the pineapple in the bottom.
Stir together the rest of the ingredients and pour over the top of the pineapple. Bake at 350 degrees F for 20 minutes. Take the cake out of the oven and let it sit for a few minutes. Run a knife around the outside of the cake and invert onto a plate. Top with fresh cranberries if desired and enjoy!
