Start with bananas that have a little green in them. The firm banana is easier to cut, doesn’t get mushy, and has a baked apple texture.
Layer the fruit on the bottom. I tried many times to put some fruit on top and it always sinks to the bottom.
Strawberries are a no go! Trust me. They get very soggy, taste funny after a day, and don’t reheat well at all! Frozen tropical fruits like pineapple/mango mixtures work well if you leave out the cinnamon.
