5 Basic Tips For Cutting Slices
1. Line The Baking Tin With Baking Paper
When making slices, ensure that you always use a baking tin that has been lightly greased and then lined with baking paper. Greasing the tin will help the baking paper to stay put in the tin.
2. Leave Your Slice Overnight Before Cutting
This isn't always possible, but if you can leave your slice overnight before cutting it, you'll find that its SO much easier to cut into neat little pieces. Always leave your slice for at least a few hours (minimum) before cutting to avoid breaking and crumbling.
3. Choose The Right Knife
Firstly, make sure your knives are sharp! It's impossible to cut a slice neatly with a blunt knife... so sharpen those babies up!!!
The type of knife you use will be determined by the type of slice you're cutting. I have two main knives I like to use:
- Small serrated knife: I cut about 80% of the slices I make with a teeny tiny Victorinox serrated knife. It's my 'go-to knife'. It's tiny and yet powerful! The serrated edge means that it cuts through chocolate topped slices easily without any cracking.
- Large flat edged knife: This knife works well on slices where you want a very sharp edge (like fudge). The slice needs to be quite firm and without a hard chocolate topping. Something like a lemon coconut slice or ANZAC slice works well with this kind of knife.
4. Cut The Slice Into Long Strips & Then Smaller Pieces
Start by placing your slice into a flat chopping board. Cut the slice into long strips. Then cut each strip into small pieces. This method gives you much more control when cutting each little piece.
5. Wipe Your Knife Clean
In between cuts, wipe your knife on a clean, damp cloth. This will keep your pieces free of extra crumbles or mixture.
How To Cut Chocolate-Topped Slices
Slices that have a layer of melted chocolate over the top can pose all kinds of problems when cutting into pieces. Often the chocolate will crack or you'll end up with jagged edges.
Top Tips For Cutting Chocolate-Topped Slices:
- Add a small amount coconut oil or vegetable oil to the melted chocolate before pouring over the slice. This helps to stop the chocolate from cracking when sliced.
- Allow the slice to set in the fridge (preferably overnight before cutting).
- Remove the slice from the fridge and place onto a chopping board 30 minutes before cutting. This will allow the chocolate to soften slightly which prevents it from cracking.
- Use a knife to gently 'score' through the chocolate layer first. This involves gently cutting lines in the chocolate until you've cut through the entire chocolate layer.
- Then use a large flat knife and press down through the rest of the slice.
- If you attempt to cut through both the chocolate layer and the slice underneath in one go, the chocolate will crack and break. Cutting through the chocolate layer first solves this problem.
How To Cut Caramel Slice/Millionaires Shortbread
Follow the tips above when cutting caramel slice. It's most important to score through the chocolate layer with a small sharp knife completely before pressing down firmly through the caramel and base (using a large, flat knife). If you try and cut all 3 layers at once, the chocolate will break and the caramel will squish out the sides.

How To Cut Fudge
When it comes to cutting slices, fudge is one of the easiest!
- allow the fudge to set in the fridge for a minimum of 3 hours
- remove the fudge from the fridge and place onto a flat chopping board
- dip a large sharp flat knife in boiling water, dry it completely and cut one long slice (the heat will help the knife to glide through)
- repeat heating and drying the knife in between each slice
- once you have long slices, cut each slice into smaller pieces (still using a hot, dry knife)
- for perfectly straight lines, place a ruler next to the knife to guide your cuts

How To Cut Vanilla Slice
Everyone's favourite classic slice can be a bit tricky to cut! Do it wrong and you'll end up with vanilla filling squishing out the sides. Do it right, and you'll have perfect neat slices!
- use a greased and lined baking tin (allowing the baking paper to overhang)
- refrigerate for a minimum of 3 hours before cutting
- remove the slice from the tin and place onto a flat chopping board
- first, use a small sharp serrated knife to cut through onto the top pastry layer
- then use a large flat knife to gently press down through the remaining custard layer and the base

I always get crumbly bits and now I know why. You truly love your slices don't you. My OCD shows up in the kitchen when I weigh burgers, cupcakes etc to make sure everything is the same size 🙂

Great tips! I find holding your breath and daring to breath is generally part of my slicing. I like your methods better!
Bake Play Smile says
Hahahaha I love that!
Renee at Mummy, Wife, Me says
This is fantastic, Lucy. Very comprehensive. I would never have thought to use a serrated edge knife. I'm the type of girl who can never wait for the slice to cool down before slicing. I will have to learn some more patience 🙂

I know Renee - it's so hard to wait, isn't it!
Nicole - Champagne and Chips says
It never really occurred to me how perfect your slices are until i read this 🙂 That tip abut wiping the knife is gold.

Hahaha thanks Nicole!

I have one of those little knives but I have never used it for cutting up slices! Now if I only had a can of condensed milk in the pantry I would be whipping up a lemon slice right now!

Oh yes you soooo need to! It's perfect!
