Get nostalgic with this easy fridge cake recipe from the Bake Off’s Frances Quinn – like a rocky road cake, this tiffin recipe is full of childhood favourites

I’ve crammed a lot of malty deliciousness into these tiffin slabs, in the form of classic malted milk biscuits and malt extract. And, in a nostalgic nod to many comforting milk-and-cookie snacks, I’ve scattered in a good helping of chewy milk bottle sweets too. If you can, choose the kind dusted in icing sugar and made with real milk: the flavour is much more ‘milky’.

Makes 15 Tiffin Biscuits

Ingredients

100g butter, roughly chopped

2 tbsp barley malt extract (see directory, p.307)

200g dark chocolate, chopped into small pieces

200g milk chocolate, chopped into small pieces

200g malted milk biscuits

100g chocolate chip cookies

100g crunchy chocolate-covered honeycomb balls, such as Maltesers

100g milk bottle sweets

Equipment

23cm square tin, greased and lined with baking parchment straps

1. Put the butter and barley malt extract in a heavy-based saucepan. Set over a gentle heat and warm, stirring occasionally, until the butter has melted. Add all the chopped chocolate and stir until smooth and combined. Remove the pan from the heat.

2. Reserve 15 malted milk biscuits and put the rest in a large bowl. Add the cookies and chocolate-coated honeycomb balls. Break up the biscuits and chocolates by pounding them with the end of a rolling pin – as if you were using a large pestle and mortar. Aim to create a mix of crumbs and larger chunks to give your tiffin a good texture.

3. Use scissors to snip up the milk bottle sweets into about five pieces each and add to the bowl containing the bashed-up mixture.

4. Add the dry ingredients to the melted chocolate mixture and stir together, combining everything thoroughly. Transfer the mixture to the lined tin. Level the surface with a cranked palette knife, spatula or the back of a spoon.

5. Arrange the reserved malted milk biscuits over the top in three neat rows of five, leaving a slight gap between each to make the tiffin easier to cut later. Firmly press them on to the top to be sure they stick.

6. Refrigerate until set, preferably overnight. To serve, remove from the tin using the parchment straps to help, and cut into portions, following the lines of the malted milk biscuits.
