I've made this chocolate chip cookie recipe many times and they turn out well. There is instant pudding in the recipe. Last night after making the dough I realized I didn't have any pudding so I left it out. They turned out flaky - difficult to stay together and not moist. Can anyone explain why? What does the pudding do anyway? I refrigerated the dough until I buy more pudding. Hopefully, they will come out better tonight. What could I have substituted for pudding? Thanks!
