If there’s one kind of recipe that no one can fail at, it’s a tray bake! Deceivingly named as the majority of them don’t require any baking, tray bakes are the perfect way to impress people with your baking skills, without actually having any. Fudge Slice is especially easy and as equally delicious.

This is another one of these recipes that Granny has perfected, so much so that when I make a tray of this Fudge Slice, it is lucky to last more than a day. Best of all, it’s ridiculously easy to make with a mere five ingredients, a bit of melting & chopping and that’s you done! And although you could mix it up with different kinds of chocolate, there’s something quite nostalgic about using the cheap little chocolate bar from everyone’s childhood.

  • Grease a 12x9 inch tin with a little excess butter/margarine. Set aside.
  • Crush the digestive biscuits, either in a blender or in [sealed] a freezer bag with a rolling pin. Transfer to a large bowl.
  • Gently melt the butter/margarine, golden syrup and half the chocolate (150g) in a bain-marie, or in short bursts in a microwave.
  • Roughly chop 8 of your fudge fingers and add them to the bowl with the crushed biscuits. Once the chocolate mixture has completely melted, add to the bowl and mix until everything is combined and coated in chocolate.
  • Transfer the mixture to your pre-greased tin and press into place with the back of a spoon. Melt the remaining chocolate (again, in a bain-marie or in short bursts in a microwave), then pour & spread on top of the biscuit base. Chop your remaining 2 fudge fingers, and scatter on top of the chocolate to finish.
  • Leave to set in the fridge for a couple of hours, or ideally overnight, before cutting into individual portions.

    1. Hi Sophie. It’s really up to you how big you want to cut you slices. I know some people like smaller bite size pieces but I’m more of a slab a piece kind of girl!

  1. Sounds good would love to try this but I don’t have a Bain Marie any suggestions what I can use as alternatives? Thank you i

    1. You just need a small pan with a little boiling water in it, then melt the mixture in a bowl larger than the pan so the bowl doesn’t touch the water.

    Nice tray bake. Very easy to make. Quite sweet though. I guess that you could use other variations of chocolate bars. Will try to use gluten free digestives next time to make the recipe suitable for people with allergens.
