How to Make Authentic Nanaimo Bars

**Crust:** In a medium bowl, combine graham cracker crumbs, sugar, and cocoa powder. Add melted butter and mix until evenly moistened. Press firmly into the bottom of a greased 9x13 inch baking pan. Refrigerate for at least 30 minutes.
**Custard Filling:** In a separate bowl, whisk together Bird's Eye custard powder, sugar, and milk until smooth. Gradually add melted butter, beating constantly. Spread evenly over the chilled crust.
**Chocolate Ganache:** In a double boiler or heat-safe bowl set over simmering water, melt semi-sweet chocolate chips and butter. Stir until smooth and glossy. Pour over the custard layer and spread evenly.
Refrigerate for at least 2 hours, or preferably overnight, to allow the bars to set completely. Once set, cut into squares and enjoy!
Optional: For an even richer crust, consider adding 1/4 cup extra graham cracker crumbs.
