I make what I call Cakebread. It's a boxed cake mix with additional stuff and baked in a loaf pan for the bread shape. Like Tropical Cakebread is coconut cake with pineapple chunks and extra coconut. Cakebread is rich and dense and does not need frosting.
Banana bread gets a bit of a tropical makeover with the addition of coconut and a sweet, citrus glaze in this Citrus Glazed Coconut Banana Bread. Lemon juice or lime juice both work well here, use whatever you have on hand.
