I've done the search on the web. Haven't come up with anything very useful. Was hoping someone here had a recipe for either coconut cake or pineapple cake like they have in Pakistan? One of my best customers is from Pakistan, and his wife is homesick for a cake from their country.

Here is the closest thing I could find for you with a google search.

Otherwise check out this site:

You can request recipe's there as well. This website had a TON of pakistani recipes.
