This Milo oat slice is a one-bowl bake with that malty Milo flavour the kids love. You mix everything together, press it into a tray and bake, and you have a batch of slice ready for lunchboxes and afternoon tea.
It makes 16 squares, so it goes a long way, and it uses simple pantry ingredients. An easy one to get the kids helping with too.
Why You’ll Love It
This one’s a regular. It’s one bowl and an easy mix, with that malty Milo flavour kids love. It makes 16 squares from simple pantry ingredients, and it’s great for lunchboxes.
The Shortcut That Makes It Work
It all goes in one bowl. You mix everything together, press it into a tray and bake, no creaming and no mixer, so the kids can help make it.
Handy Tips
Mix until you cannot see any dry flour, so it bakes evenly. Press the mixture into the tray firmly so the slice holds together when you cut it. Line the tray with baking paper so you can lift the whole slice out easily. Let it cool before slicing so it sets and cuts cleanly.
Make It Your Way
Stir a handful of chocolate chips or sultanas through the mix. You can use cocoa powder instead of Milo, though it will not have the same malty flavour. Add an extra tablespoon of sugar to balance it if you do. Cut it into bigger or smaller squares to suit.
How to Store It
Keep it in an airtight container at room temperature for up to a week. It also freezes well, so you can keep a batch in the freezer for lunchboxes.

I love all your recipes as there so easy to follow and find in the aldies store
Thank you Dorothy. That made my day 🙂
Mine was quite thick and fudnt appear as moist when I put it in the dluce tray.
Hi Kim, sounds like it may have needed a touch less time, or your tray was smaller/deeper than mine (I used a 19cm x 28 cm tray). A smaller tray means a thicker slice that needs extra time and can dry at the edges. It’s worth adding a few minutes and checking early next time. I’ve also updated my instructions. Let me know how it goes the next time.
Taste was delicious 😋 But the slices came out a bit dry, not sure what I did wrong. I still managed to scoff a lot of them and my family loved them
Hi Debbie, glad the taste was a hit :). Dryness here is usually from slightly over-baking. Check it a couple of minutes before the 20-minute mark and pull it out as soon as it’s golden, as it firms up more while cooling. Also worth checking your tray size, as a smaller tray makes it thicker and needs longer to bake through.
Absolutely love this! Family favourite! Just made a batch with 3
.5 yr old granddaughter!! She too loves them!! Thank you Stef! 😊
I’ve noticed you can get 2 different sorts of Milo , Singapore or Ghana , which one did you use ?
I use the regular Nestle Milo from the supermarket. From what I can tell, the Australian version is different to the Singapore and Ghana versions. I now want to try those 🙂
