Well the base of this recipe is just fine for making any sort of cookies I guess. If you want them lighter coloured..then use white bastard sugard versus the easy brown one I did hehe.
But yeah..half of the amount was fine. Better said...i used half of the amount from the original recipe (the amounts you see here are already half) and still I put some in the freezer for a next binge session haha.
For us something like 2 cookies per person is fine because they go big and usually they dont go so well overnight.
Go for it! And practise before christmas ;))
