About the bake

Nanaimo Bars are a custard centred treat from the Canadian city of Nanaimo. If you have never tasted this before we really recommend that you give this recipe a try. Nanaimo Bars require no baking, so there is no need to pre-heat an oven. The only cooking to happen in this recipe will be microwaving the chocolate for the topping.

  1. Step 1:

    To make the base, line a shallow 28x20 cm cake tin with baking parchment.

  2. Step 2:

    Melt the butter and chocolate together in a small pan or in the microwave. Stir in the biscuit crumbs, coconut and walnuts. Press the mixture firmly into the cake tin and leave in the fridge to set for about 30 minutes.

  3. Step 3:

    To make the filling, place the egg yolk and milk in a small bowl over a pan of simmering water, making sure the bowl does not touch the water. Whisk until the milk is warm then add the custard powder and gradually add the butter and vanilla, whisking until smooth and soft. Gradually beat in the icing sugar, then spread over the chilled biscuit base.

  4. Step 4:

    Chill for 30 minutes until set.

  5. Step 5:

    Melt the chocolate in the microwave or in a bowl set over a pan of gently simmering water. Spread over the chilled icing and leave to set for a couple of hours. Cut into squares.
