Expert Tips & FAQ's
Yes, absolutely, 'quick oats' work perfectly well in this recipe.
Ovaltine or Horlicks are similar malted milk powders, however Milo is probably the most common malted milk used here in Australia.
Allow the slice to cool completely in the baking tin before cutting, as this makes it less likely to crumble than if you slice it while still warm.

Delicious! So easy to make. My 11 year old whipped this up today. Unfortunately it didn’t last long as multiple pieces where scoffed down by both the kids and adults. Will definitely be making this again especially when I need to pull together school snacks in a hurry.
Lucy
Hehehe this one always disappears very fast! So glad it was enjoyed!
Lillian
Is milo powder like cocoa powder. I’ve never heard of milo before and not sure if I can buy it where I live. ..Would love to try those.
Lucy
Hi Lillian, it's much sweeter than cocoa powder. Milo is a malted milk powder (similar to ovaltine!).
Naomi
