Author's Notes

Once you’ve mastered the basic technique, you can try adding all sorts of different flavour combinations to your fridge cake, using up whatever you have in the cupboard. Give these ideas a go:

Add a handful of chopped nuts, such as hazelnuts, walnuts or almonds.

Break in different types of biscuits – whatever you have to hand!

Add some chopped chocolate bars or your favourite M&S treat bags to make it even more indulgent.

Add broken bits of white chocolate.

Add a handful of cereal, such as puffed rice or cornflakes, through the mixture for extra crunch.

Add pieces of your favourite sweets, such as Percy Pigs or Colin the Caterpillar.

Method

HIDE IMAGES
Step 1
Grease and line a large baking tin with baking paper.
Step 2
Place the digestives (150 g) in a freezer bag and crush with a rolling pin until they’re broken into a mixture of smaller pieces, with none bigger than a 10p piece. Set aside.
Step 3
In a large saucepan, melt the butter (150 g) and the chocolate (200 g) over a low heat – keep stirring until melted and smooth. Remove from the heat and allow to cool for 5 minutes.
Step 4
Stir the crushed biscuits, most of the marshmallows (85 g) , ⅔ of the chopped mini whips (80 g) and the dried fruit (50 g) , if using, into the chocolate mixture until all your stir-ins are coated.
Step 5
Tip the mixture into the lined baking tin and spread it out into the corners. Decorate with your remaining marshmallow pieces (15 g) and chopped up mini whips (40 g) , pressing lightly into the mixture. Chill for at least 2 hours, then cut into fingers.
