I have tried quite a few different recipes for this Canadian favorite because I occasionally loose the one my mom wrote out for me when I left home. This is my mom's recipe and let me assure you, it is the BEST! It turns out great every time and I always get asked for the recipe. They take a while to prepare but nothing tastes more like home then some good old Naniamo Bars. Let me assure you, they are worth the trouble so I usually double the recipe :)
½ cup butter
3 Tbsp cocoa
¼ cup sugar
1 tsp vanilla
2 cups graham cracker crumbs
½ cups chopped nuts
½ cup coconut
In double boiler melt butter. Add cocoa and sugar. Stir until smooth. Take off heat and beat it egg and vanilla. Add graham cracker crumbs, nuts and coconut. Press mixture evenly into a lightly greased 9 x 9 baking pan. Refrigerate until firm (about 30 min).
¼ cup butter
2 Tbsp custard powder*
2 cups icing sugar
½ tsp vanilla extract
2 Tbsp milk
Cream butter and vanilla. Add icing sugar and custard powder. Slowly add milk and adjust as needed so the mixture is still thick but able to spread. Spread filling over bottom layer and refrigerate again until firm (about 30 min).
* I have had a hard time finding custard powder in the US. I have found it at occasionally in grocery stores and usually at the World Market. If you really just can’t find custard powder I have heard that you can substitute the same about of vanilla pudding powder but I have never tried it.
4 oz or ½ cup bitter sweet chocolate
1 Tbsp butter
2-3 Tbsp milk (if using chocolate chips instead of baking chocolate)
In double boiler melt chocolate and butter. Add milk if needed to make mixture smooth. Poor over filling and refrigerate.
