Twinkie Filling

by Lindsey F

Hi everyone,
I'm new here and am desperate for a Twinkie cake and filling recipe that I can follow in England. I have no idea what is meant by 'shortening' could someone please explain and any recipe must also be Halal as I am Muslim so a vegetarian recipe would be brilliant. I also need metric measurements not all the 1 cup, half cup measures. Can anyone help......I want Twinkies please!!!!!!
