Here’s a classic no-bake slice that’s quick to make, full of flavour, and ideal to pop on a plate when friends drop by — or to keep in the fridge for when you fancy a little treat.
This is such an easy slice to make — no baking, except for toasting the walnuts and coconut. Everything else is simply mixed together and left in the fridge to set. A handy recipe when you want something sweet without fussing over the oven.
Did I Change Anything?
No, not a thing… but I certainly would next time. The coffee flavour is very strong. I’m okay with that because, as you know, I tend to go a bit excessive with flavours — but it’s not to everyone’s taste. If you prefer something gentler, you could swap the coffee for ground ginger or cardamom for a warm, spiced flavour.
I also sprinkled sea salt flakes over the top for a nice contrast, which worked well. And instead of blending the biscuits in the food processor, I used a rolling pin to crush them into chunky pieces — the old-fashioned way we used to do for a no-bake slice. I think it gives more texture and bite.
Nisha’s Input
Nisha suggested using more chocolate and less coffee. She even thought cocoa powder instead of coffee might be nice for a softer, chocolatey flavour. Worth trying if you’re not a coffee fan.
She also suggested that the flavour of the base layer could be improved with the addition of just a tablespoon of golden syrup, great idea!

Great to hear! Wine biscuits are plain sweet vanilla biscuits, but you could use any sweet biscuits. Happy baking, Janet.
