Caramel Coffee Walnut Slice

This recipe should come with a warning: make sure you’ve got lots of people to share it with, because if not you’ll end up wanting to eat the whole thing yourself!

This is an old recipe from my childhood – I’d make caramel slice, wrap pieces up in baking paper and give it away as gifts. It is incredibly indulgent and decadent, so you only need a small piece…but I’ll admit I can’t keep going back and slicing off a bit more every time I pass the kitchen bench when it’s around! You can turn this into a classic caramel slice by omitting the coffee and walnuts.

I don’t usually bake with so much sugar and butter, but hey there’s nothing wrong with a little treat now and again is there? What did Oscar Wilde say? “Everything in moderation, including moderation!” Enjoy x


Print Recipe


  • butter 125g
  • fine rolled oats or plain flour 3/4 cup (use GF flour if you need to)
  • desiccated coconut 3/4 cup
  • brown sugar 3/4 cup


  • butter 125g
  • instant coffee granules 1 1/2 tablespoons (optional)
  • golden syrup 1/3 cup
  • sweetened condensed milk 2 x 395g can


  • dark chocolate 175g
  • butter 50g
  • walnuts 3/4 cup roughly chopped (optional)


Preheat oven to 180degC. Line a 20x20cm tin with baking paper.

  1. To make the base, place oats/flour, coconut and brown sugar in a bowl. Add melted butter and mix together until well combined. Press mixture into prepared tin and bake for 15 minutes or until light golden brown.
  1. To make the filling, place butter, coffee granules (if using), golden syrup and condensed milk in a saucepan and stir over low heat until the butter has melted and coffee has dissolved. Pour caramel over the cooked base and place back in the oven to cook for a further 25 minutes until golden and a little bubbly. Refrigerate until cold.
  1. Place chocolate and butter in a bowl and microwave for 1-2 minutes (stirring frequently) until melted, or melt together in a double boiler, or in a heatproof bowl over a pot of simmering water. Pour over the set caramel and smooth over with a spatula. Sprinkle over walnuts (if using). Refrigerate until cold before cutting into pieces.


  • Tip: To get nice, clean-cut slices, dip a sharp knife into hot water for 5 seconds and dry with a tea towel before each cut.
