It was at Freddy's where I first saw a Nanaimo bar. Chocolate and coconut crust base, custard middle, chocolate top. Mmmmm.
Here's the recipe I use (from www.hiddenponies.com):
BASE:
¾ cup butter or margarine
¼ cup sugar
6 tbsp cocoa
1 egg
1 tbsp milk
1 tsp vanilla
2 cups graham cracker crumbs (*see note for substitutions)
1 cup coconut
½ cup chopped walnuts (OPTIONAL)
MIDDLE LAYER:
½ cup butter or margarine, softened
6 tbsp milk
4 tbsp custard powder (I had to go to the import store for this, which was awesome, because I love the import store)
4 cups powdered sugar
TOP LAYER:
8 oz semisweet or dark chocolate
1 tbsp butter
Instructions
BASE: Combine first 6 ingredients in large saucepan. Heat and stir over medium-low heat until mixture is smooth. Remove from heat.
Stir in graham crumbs, coconut, and walnuts. Pack firmly into ungreased 9x13” pan. Chill while you prepare the middle layer.
MIDDLE LAYER: Beat all 4 ingredients together in medium bowl until smooth. Spread over first layer. Chill for 45 minutes.
TOP LAYER: Melt chocolate and butter in a small bowl at 50% power in microwave. Microwave for about 1½ minutes, stir and microwave another 30 seconds or longer if needed, stirring frequently. Spread fairly evenly over middle layer. Chill for 1 hour, then score chocolate with a sharp knife and return to fridge to chill completely before cutting into bars.
