Thank you so much for all the great replies and advice...I never thought to add pudding to the cookie recipe..can't wait to try it. I do have to say, tho, that even tho my CCC aren't soft (they will be soon!), I do make a mean PB cookie, and this recipe uses sweetened condensed milk and biscuit mix, and of course the PB, but these are gooey and chewy and stay that way. So I have thought about at least using biscuit mix instead of regular flour....
Are you making the PB cookies from the Eagle Brand cookbook? That's what I use at Xmas to make my thumb print cookies and ones with candy kisses. They are great!
I have never used pudding in my cookies either but now I will have to try it. Using the white chocolate pudding sounds yummy in CCC.
