My buddy Sandhya made this cake from your site & told me about it ,how it tasted too good .That inspired me to make this cake. Made a few changes to the recipe - added margarine instead of oil , added caramel syrup to get a darker colour, added walnuts instead of pecans & pineapple cooked in sugar syrup instead of canned one .It tastes great ,my parents loved it .Thank you DK .
Nope, they ARE pecans :) --DK
Please refer "tips" section --DK
Personally if you ask me, this cake is all about Bananas + Pineapple + Pecan. It is the base for the cake hence subbing these will not be technically "Hummingbird cake". If that's not a issue, you can certainly try with applesauce. I cannot comment on the taste having not tried it myself. :)
