NANAIMO BARS RECIPES

Steps:

• Line an 8-by-8-inch (20-by-20-centimeter) metal baking pan with parchment, allowing parchment to overhang by about 2 inches (5 centimeters) on two sides.
• Prepare the base: In a double boiler, or a heatproof bowl placed over a saucepan of boiling water, whisk butter with granulated sugar, egg, cocoa powder and vanilla until melted. Continue whisking until mixture thickens slightly, 1 to 2 minutes. Remove from heat.
• Stir in crumbs, coconut and nuts until the mixture is well combined and resembles wet sand.
• Transfer mixture to the parchment-lined pan and use your fingers to press it into an even layer. Transfer pan to the refrigerator to chill until firm, at least 15 minutes.
• Meanwhile, prepare the buttercream: In a stand mixer fitted with a paddle attachment, cream butter on medium speed for about 1 minute. Add heavy cream and custard powder and mix until combined, scraping sides and bottom of the work bowl as needed. Add 1 cup confectioners’ sugar and mix on low until incorporated. Add remaining confectioners’ sugar and mix on low until combined, scraping the bottom of the bowl as needed, then mix on medium-high speed until smooth, light and fluffy, 2 to 3 minutes.
• Remove pan from refrigerator. Dollop the buttercream on top of the base layer then gently spread it evenly on top using an offset spatula. Transfer pan to the refrigerator to chill until buttercream is set, about 30 minutes.
• Prepare the topping: In a small, heavy saucepan or a double boiler, heat the chocolate and butter over low, stirring often, until melted and evenly combined, 2 to 3 minutes. Remove from heat. Take pan from refrigerator and pour chocolate on top of buttercream layer. Working quickly and carefully, spread the chocolate evenly over the buttercream using an offset spatula. Sprinkle with flaky sea salt, if using.
• Return pan to refrigerator and chill until chocolate hardens, about 25 minutes.
• To serve the bars: Lift excess parchment to remove Nanaimo square from the pan. Cut into 16 2-inch (5-centimeter) squares. Store bars in the refrigerator until ready to serve. Bring to room temperature before serving. Store remaining bars in the refrigerator for a few days, or wrap well and freeze.

Steps:

• For the base, first prepare a double boiler on your stove: Fill a large pot about a quarter full of water and bring to a boil. Reduce the heat to a simmer and place a heatproof bowl overtop. Make sure the bottom of the bowl is not touching the water.
• In the double boiler, melt the butter, sugar, and cocoa powder, mixing regularly until smooth. Add the  egg, stirring constantly until the mixture has just started to thicken a bit, about 1 to 2 minutes.
• Remove the bowl from the heat and stir in the graham cracker crumbs, coconut, and salt.
• Line a 9- x 13-inch baking pan with parchment paper. Spoon the graham cracker mixture inside, press it down firmly and evenly, and refrigerate until solid, about 2 hours.
• For the creamy middle layer, in a stand mixer with the paddle attachment, whip the butter until light and airy, about 2 minutes on medium speed.
• Add the milk, custard powder, salt, and icing sugar and mix on low speed until all the ingredients have been incorporated. Increase the speed to medium and whip until light and fluffy, about 5 minutes. Pour this creamy mix onto your solid base, make sure it’s evenly spread out, and refrigerate for about 2 hours.
• For the chocolate topping, melt the chocolate and cream together in a double boiler over low heat, stirring  constantly. When the chocolate has melted, remove from the heat and let rest for about 5 to 10 minutes. You want the temperature to come down but still keep the chocolate completely melted. Pour this over the cream layer and, using a rubber spatula, spread it out evenly. Chill in the fridge for at least 3 hours before serving.
