Ingredients

Scale

Bottom Layer:

  • 1/2 cup (115g) unsalted butter
  • 1/4 cup (50g) granulated sugar
  • 5 tbsp (30g) unsweetened cocoa powder
  • 1 large egg, beaten
  • 1 tsp vanilla extract
  • 1 3/4 cups (175g) graham cracker crumbs
  • 1 cup (65g) shredded sweetened coconut
  • 1/2 cup (50g) chopped walnuts (optional)

Middle Layer:

  • 1/2 cup (115g) unsalted butter, softened
  • 2 tbsp heavy cream
  • 2 tbsp vanilla custard powder (or instant vanilla pudding mix)
  • 2 cups (250g) powdered sugar

Top Layer:

  • 4 oz (115g) semi-sweet chocolate, chopped
  • 2 tbsp unsalted butter

Instructions

  1. Prepare the Bottom Layer:
    • In a medium saucepan, melt the butter over low heat. Stir in sugar and cocoa powder until smooth.
    • Gradually whisk in the beaten egg, cooking gently until the mixture thickens (about 1–2 minutes).
    • Remove from heat and stir in vanilla, graham cracker crumbs, coconut, and walnuts.
    • Press the mixture firmly into a greased or parchment-lined 8×8-inch (20×20 cm) pan. Chill in the refrigerator while preparing the next layer.
  2. Prepare the Middle Layer:
    • Beat together the softened butter, heavy cream, custard powder, and powdered sugar until smooth and fluffy.
    • Spread the custard mixture evenly over the chilled base layer. Return to the refrigerator to set.
  3. Prepare the Top Layer:
    • Melt the semi-sweet chocolate and butter together in a heatproof bowl over a pan of simmering water, or microwave in short intervals, stirring until smooth.
    • Spread the melted chocolate over the custard layer. Smooth with an offset spatula.
    • Refrigerate until the chocolate is firm.
  4. Cut and Serve:
    • Let the bars sit at room temperature for a few minutes before cutting to prevent the chocolate layer from cracking.
    • Slice into squares or bars and enjoy!

Notes

  • For a nut-free version, omit the walnuts and increase the amount of graham cracker crumbs slightly.
  • Store Nanaimo Bars in an airtight container in the fridge for up to a week or freeze for longer storage.
  • Bring to room temperature before serving for the best texture.
