These are delicious and fun to make! My husband and I are really enjoying them. The only change I made was to use "craisins" because I do not like raisins. The tartness is nice with the sweetness of everything else, but they are not very "tropical." Maybe next time I will try chunks of dried pineapple or mango. Since this recipe contains raw bananas, and I knew we couldn't use them all before they went bad, I wrapped each bar individually and put them in the freezer. In the morning we each take one out and by the time we need a snack they are thawed.
