I guess you know the, product pretty well! Is it not available from Europe? Maybe they will ship to Singapore. Other than that, there are a other franchises I am sure you can start up.
http://www.bopaloo.com.tw/ is an American Frozen custard, which a friend of mine is running in Taiwan. Not yet a Franchise, but they are working on it.
They have two successful shops now, took 4 years to build up. I think the main product really, that brings in the money Is the ice cream custard birthday cakes.
The owner just did a course on cake making, and they never looked back.
Don't just dive into any franchise, deep research is needed, otherwise you will get your fingers burnt!
