Choccy Rocks or Choc Chip Cornflakes Biscuits

The Choccy Rocks or Choc Chip Cornflakes Biscuits are one of a zillion delicious, buonissimo, scrummy, yummy recipes from Mum’s cookbook collection. Mum, 76, or Nonna to her 20+ grandchildren — aged 30 to 7, has the honorary title of ‘World’s Best Cook’. Why? Because, you’ll often hear, as the grand-kids tuck into their second or third biscuit, ‘Nonna, you’re the best cook in the World!’  Hence, her prestigious world title. For that matter, her seven children, aged 56 to 42,  have loved her cooking for longer.IMG_7074

It was as far back as 1980 when Mum was only 40 years old, that she came across the Choccy Rocks recipe. She was grocery shopping at the, then locally owned Philip Leongs, Vincent Village, Townsville. This was before the proliferation of the giant supermarkets. She happened upon a food demonstration promoting, Dark Chocolate Bits. She tasted a sample of the Choc Chip Cornflakes Biscuit and liked the flavour and texture so much that 37 years on, it has become a family favourite in her extraordinary recipe repertoire.

Recipe Tips

When Mum bakes this recipe, she always makes ‘triple’ because she likes to have backups in the freezer. That is if they make it to the freezer when her kids and grandkids are around.

Also, Mum likes to experiment and modify the original recipe. When she added an extra 50g of chocolate bits and sultanas, the extra ingredients changed the balance of the mixture, which made it more crumbly as you bit into it. Or she’ll combine Chocolate Bit colours — dark, white and milk for effect and taste. Once again, the taste changes and the kids notice. The white choc bits are sweeter, whereas the dark chocolate has 40% cocoa for a contrasting flavour. Consider this when experimenting.  She also likes to plump her sultanas, if they are too dried out. The sultanas are submersed in hot water so they are less dried out. Depending on the brand, sultanas can be more or less drier, therefore may or may not need plumping. Below is the original recipe. Enjoy!

  1. I can see why they’d be so popular..yummy! I too vary recipes from time to time and even though I do measure some ingredients a lot of my cooking was/is by trial and only a few errors. Thank you for linking up for #lifethisweek 22.52. Next week: View From Here.

    • Far too moorish. I also love dipping it my tea because the chocolate bits start to melt… so nice. I like seeing my Mum using trial and error — gives to me the confidence to have a go and then a better go. Thinking of you. xox M


    • Thank you. I’m a very visual learner and I thought it would make it easier when my nieces and I cook with Mum. They love the idea that their Nonna’s recipe is on the internet. So cute. Also far too delicious that I eat more than two.
