Nanaimo Slice

A no-bake Canadian classic. with a chocolate biscuit-coconut base, a sweet custard buttercream filling and a dark chocolate topping. An excellent option for morning tea.

My wider family hosts a monthly quiz night where we learn about different countries. Recently my sister held a Canadian-themed quiz night so I finally made a recipe I'd been eyeing up - Nanaimo Slice. This Canadian classic (known as Nanaimo Bars) is another great no-bake option. It consists of a melt and mix base, a custard cream filling and decadent dark chocolate on top. I gave some to my Canadian friend to try and she said it tasted legit!

Ingredient notes:

• Biscuits: Any type of plain biscuits will work in this recipe. I like digestives as they have a little more texture to them than super plain bikkies.
• Custard Powder: This is important as it gives the filling its delicious custard flavour and yellow colouring.
• Chocolate: Dark chocolate is definitely the key here. It balances out the sweetness of the filling.

Step by step instructions:

Line a 17 x 27 cm baking tray with baking paper. Pulse the biscuits in a food processor until fine. Add the walnuts and coconut, then pulse a few more times until roughly chopped.

In a large saucepan over low heat, melt the butter. Stir in the caster sugar and cocoa powder until the sugar has dissolved. Remove from heat and let cool slightly. Whisk in the egg, mixing quickly to prevent scrambling.

Stir in the crushed biscuit mixture until fully combined. Press firmly into the lined tray and freeze while making the filling. In the bowl of a stand mixer whisk together the butter, cream, custard powder and icing sugar until light and fluffy - scraping down the sides as you go.

Spread the filling evenly over the chilled base and refrigerate. Melt the dark chocolate and butter in the microwave for 90 seconds. Let it sit, then stir until smooth. Pour the chocolate over the filling layer and spread evenly to the edges.

Refrigerate for a few hours or overnight until firm. Slice into pieces and store in an airtight container in the fridge. Let the slice warm to room temperature before serving.

Storage:

Store the slice in an airtight container in the fridge for up to 1 week. Keep layers intact by placing a sheet of baking paper between stacked pieces.

Wrap individual pieces tightly in cling film and place in an airtight container or freezer bag. Freeze for up to 2 months. Defrost in the fridge overnight before serving.

Top tips:

Chill each layer before adding the next to keep them neat and tidy.
