Caramel Nut Slice is the treat you make when you want something that looks fancy but takes about ten minutes of actual effort.
It's got a buttery shortbread base, whatever nuts are sitting in your pantry, and a caramel layer that basically makes itself. If you're already a fan of my traditional caramel slice, my white chocolate caramel slice or my caramel oat slice, you're going to want this one in the rotation too.

Oh so addictive! I used pecans, walnuts, peanuts and cranberries plus white chocolate buttons. I put the nuts in the blender, so a mixture of crushed and small pieces - a good texture for us oldies. Definitely at the top of my favourite slices list!

That's the thing about this slice - everyone tweaks it their own way and it still works. Grab whatever nuts you've got, and let's get into it.

Why You're Going To Love This Recipe
- Easy yet impressive - no complicated techniques, but it looks bakery-worthy.
- Totally customisable - swap the nuts, swap the chocolate, use what you've got.
- No fancy equipment - just a bowl, a spoon and a baking tin.
- Genuinely different to Millionaire's Shortbread - same shortbread base, but a nutty caramel-and-white-chocolate top instead of a solid chocolate layer.
- Thermomix or conventional - both methods are in the recipe card, so nobody misses out.
Caramel Nut Slice Ingredients
Full quantities are in the recipe card down the bottom - here's what actually needs explaining.
- Nuts - macadamias, pecans, almonds, walnuts, peanuts, whatever you've got. See the Variations section below for how they actually differ.
- White chocolate chips - use a proper baking brand like Cadbury or Nestlé. Cheap eating chocolate can split and go oily when it hits the hot caramel.
- Sweetened condensed milk - full-fat, not the reduced-fat or "lite" tin. This is the one ingredient that actually matters for whether your caramel sets properly - more on that in Recipe Tips.
Variations
- Choose your nut: macadamias are soft and buttery and make the whole slice taste a bit more luxe. Pecans bring a rich, almost toffee-like flavour that plays really well with the caramel. Almonds are the budget pick and give you the most crunch. Walnuts are earthier and slightly bitter, which some people (me included) actually prefer against all that sweetness. My go-to combo is macadamias, pecans and slivered almonds.
- Swap the white chocolate chips for milk or dark chocolate chips if you want it less sweet.
- Add a handful of craisins (dried cranberries) with the nuts for a tart little contrast.
- Want it more like a Millionaire's-style slice? Skip the white chocolate chips entirely and drizzle melted dark chocolate over the top once the caramel has cooled and set, then chill until the chocolate hardens before slicing.
- No-bake version: for a genuinely no-bake take, swap the baked shortbread base for a pressed crumb base (crushed plain biscuits mixed with melted butter, pressed into the tin and chilled until firm instead of baked). Make the caramel on the stovetop instead - condensed milk, a knob of butter and a spoonful of golden syrup, stirred over low heat for about 8 minutes until thickened - then pour over the nuts on the chilled base and refrigerate until set instead of baking. It's a different method, not just a different topping, so treat it as its own version rather than a straight swap.
How To Make Caramel Nut Slice
Full quantities and method are in the recipe card at the bottom of the post - here's the quick version with photos.
- Step 1: Mix the dry ingredients. Preheat the oven to 160°C fan-forced and line an 18cm x 28cm tin. Sift the plain flour and self-raising flour into a bowl, then stir through the brown sugar and coconut.
- Step 2: Add the butter. Pour in the melted butter and mix well - the mixture will look crumbly once it's combined, and that's exactly right.
- Step 3: Press and bake the base. Press the mixture firmly into the tin and smooth the top with a spoon. Bake for 15 minutes or until lightly golden.
- Step 4: Add the toppings. Once the base is baked, scatter the chopped nuts and white chocolate chips evenly over the top.
- Step 5: Pour over the condensed milk. Gently pour the sweetened condensed milk all over the nuts and chocolate chips, right to the edges.
- Step 6: Bake again and cool. Bake for a further 15-20 minutes until the condensed milk has turned a deep golden caramel. Cool completely, then chill in the fridge before slicing.
Team Thermomix? The Thermomix method only does the prep - melt the butter in the bowl for 3 minutes, 100°C, Speed 2, then add the flours, brown sugar and coconut and mix for 10 seconds, Speed 4 (scrape down and repeat if needed). You'll still bake it in a normal oven exactly as above - the Thermomix doesn't do any of the actual baking here, it just saves you dirtying a mixing bowl.
Recipe Tips
- Use full-fat sweetened condensed milk, not reduced-fat. It's the difference between a caramel that actually sets and one that stays gluey.
- Caramel too runny even after cooling? It's almost always one of two things - reduced-fat condensed milk was used instead of full-fat, or the second bake was pulled a few minutes too early. It should be a deep golden colour all over, not pale in the middle, before it comes out.
- Slice cracking or crumbling when you cut it? It needs longer in the fridge - give it a good few hours, or overnight if you can. A warm knife helps too - run it under hot water and dry it between cuts so it glides through instead of dragging.
- Storing: keep in an airtight container in the fridge for up to 5 days.
- Freezing: wrap it well (double wrap in plastic wrap or foil) and freeze for up to 1 month. Thaw overnight at room temperature before serving.
Caramel Nut Slice FAQs
Honestly, whatever you like or have on hand. Macadamias are soft and buttery, pecans have a rich toffee-like flavour, almonds give the most crunch and are the cheapest, and walnuts add an earthy, slightly bitter edge. My favourite combo is macadamias, pecans and slivered almonds - but a mix of two or three types always works better than just one.
Not quite. Millionaire's Shortbread has a thick caramel layer topped with a solid slab of chocolate. This caramel nut slice uses the same style of shortbread base, but the top is a caramelised condensed milk layer studded with nuts and white chocolate chips instead of a solid chocolate shell - so it's chewier and a bit less rich per bite.
Two likely culprits. First, check you used full-fat sweetened condensed milk - the reduced-fat version won't set properly no matter how long you bake it. Second, it might just need longer in the oven during the second bake - you're looking for a deep, even golden colour right across the top, not just around the edges.
Yes. Let it cool completely, double wrap in plastic wrap or foil, and freeze for up to 1 month. Thaw it overnight at room temperature before serving - don't rush it in the microwave or the base can go soft.
Yep - swap the plain flour and self-raising flour for a good gluten-free flour blend, and double check your chocolate chips are certified gluten-free (most are, but worth a quick label check). The texture of the base is very slightly different but still delicious.

Notes
- Use full fat (not skim) sweetened condensed milk. Full-fat gives a creamier taste and sets firmer.
