The Best Nanaimo Bars

Erika Marucci
These three layer Nanaimo bars are sweet, delicious, simply the best! It’s a classic no-bake Canadian treat with a fudgy graham cracker base, a creamy custard layer filling, and then a chocolate ganache topping that will keep you coming back for just one more bite!

  • ½ cup butter

1ST LAYER

Remove from the heat and slowly add the beaten egg, whisking quick and hard, place the pot back on the heat (low/medium) and continue to cook for approximately 2 minutes until the mixture is smooth and thickens.

2ND LAYER

3RD LAYER

  • In a medium pot melt together the butter, milk and chopped chocolate until smooth. Let cool, then spread evenly over the 2nd layer. Refrigerate for at least 1 hour or until firm. Cut and serve. Enjoy!

Notes

Mary Howe instant vanilla pudding mix powder can be substituted 1:1 if you can’t find custard powder. 
Nanaimo bars can be refrigerated in a sealed container for about a week. The bars are best chilled as the filling softens at room temperature. 
Nanaimo bars can also be frozen. Freeze in an airtight container for up to 3 months. You can freeze individual pieces or the whole pan. Thaw overnight in the fridge.
