While we're waiting for experts how about this? Crumble the digestives and press to the bottom of a pie plate like a cookie or graham cracker crust. Make a chocolate custard out of everything else, except the flour, and fill your pie with it.
If it were winter where you are I would suggest a Chocolate Self Saucing Pudding but if y'all are hot, then it wont do at all!!
When winter does come tho', do try one! Probably the most requested cold weather pudding in New Zealand. Well, that and Golden Syrup Pudding. And Sticky Date, and and and..lol
Ah. I thought it was maybe something like Ex-Lax and I was thinking to myself, "Why the **** would you want to make this for someone unless you hated them?"
With everything, except the chocolate digestives, u could make pancakes.
Put some cocao and the sugar if u want, in the pancake mix, and the pancakes will have a nice chocolaty look. Then when they are cooked, smear the chocolate sauce on them.
