If you're unfamiliar with hummingbird cake, it's a cake spiced with cinnamon and nutmeg; chock-full of mashed banana, pineapple, nuts and coconut; and finished with a cream cheese frosting. I absolutely love hummingbird cake, so I decided to make a bar cookie version using all those flavors. These bars have a spiced shortbread crust and creamy cheesecake filling infused with mashed banana, and are studded with pineapple, coconut and candied pecans on top. I think you're going to love them!
