Mine didn't harden quite as much as I'd have preferred, but it could be my eggs were bigger than expected, or I'll add a little more flour next time.
And in some, I added cocoa and a little milk to counter the additional dry ingredients.
Note I used a variety of chic chips, I'd suggest not using caramel ones, too sweet.
Easy to do and I have some in freezer, ready and waiting.
I do wonder if poss to just use self raising flour as a short cut and 1 ingredient less.
Easy and yummy!
