Chocolate rainbow traybake

    Kids will love this moreish homemade treat. The 'rainbow' is thanks to Smarties or M&M's - whichever you choose. You could also use plain chocolate chips if you don't want the rainbow effect!

    Great easy recipe to make with kids BUT personally the 'rainbow' effect doesn't really work so I wouldn't bother with smarties & just use chocolate instead. I would also pre cook the biscuit base then mix the condensed milk, coconut & walnuts together first then spread onto the cooked base & top with melted chocolate yum!  -  30 Mar 2015


    YUM! Very satisfying, and rich. I have to fight my kids to get one!) I only had regular-sized M&M's, and they worked just fine. I also used the fat free condensed milk and it didn't change the outcome at all.  -  20 Nov 2001  (Review from Allrecipes US | Canada)


    I don't think I will be making these again. when I tried to cut them, it was hard to get them out of the pan without them falling apart and most of the topping fell off. After reading the other reviews, I guess I could have done something wrong, but with such a simple recipe, I am not sure what I could have possibly done to make them turn out that way.  -  16 Aug 2008  (Review from Allrecipes US | Canada)
