In the spirit of things that are not good for you, but worth it anyway, I offer Nanaimo Bars.
Nanaimo Bars are made in three layers:
Base:
Melt 2 squares of Semi-Sweet Chocolate over hot water.
Combine with:
1/2 cup (125 ml) softened butter
2 tablespoons (25 ml) sugar
1 teaspoon (5 ml) vanilla
1 egg
Mix well, then add:
2 cups (500 ml) graham wafer crumbs
1 cup (250 ml) flaked coconut
1/2 cup (125 ml) chopped walnuts
Mix well. Press into 9-inch (2.5L) square pan. Chill.
Filling:
Combine 4 tablespoons (60 ml) Custard Powder* with 6 tablespoons (100 ml) milk.
Add to 1/2 cup (100 ml) butter.
Beat in 4 cups (1000 ml) icing sugar (aka confectioners sugar in the USA, I think) until smooth.
Spread over base; chill 15 minutes.
Glaze:
Melt 4 squares Semi-Sweet chocolate with
1 tablespoon (15 ml) butter over hot water.
Spread over the chilled custard layer. Chill again.
Cut into squares and serve. They freeze well, so you can hide some for a later date, if you have the willpower.
*The secret ingredient is the Custard Powder. The two brand names here are Birds and Harry Horne.
