3 tablespoons treacle (can substitute jam or preserves but not jelly) 
1-1/4 cup self raising four 
3/4 cup margarine 
1cup sugar 
2 eggs 
A little milk—maybe 2-3 tablespoons 

Cream together sugar and margarine. Add eggs and mix well. Add flour and milk.  Grease a large (about 12 cup) microwave safe bowl. Place the treacle in the bottom. Place batter on top. Cover with Saran Wrap. Microwave for 6-8 minutes. Leave to set for a couple of minutes.  Turn out on a plate. *Serve with egg custard and a little drizzle of treacle syrup on top. 

*Bird Instant Custard Powder Mix 
Available in England or where English food products are sold. (It is like a rich vanilla pudding) 

*Tate & Lyle Treacle (a thick rich syrup—like our  pancake syrups only finer) 

Sue and her mother adapted this recipe for American use in a microwave and said it turns out 95% of the time.  She is not aware of any substitute for the egg custard.  As far as she knows there's nothing like it in the U.S. (and Barb Agrees).
