Uh-oh. You accidentally added too much butter to your cookies.
On the one hand: Awesome! Butter is delicious!
On the other hand: Oh crap. Flat-as-a-pancake cookies. Serious bummer.
Well, suffice it to say that this comes from experience. I seem to be chronically incapable of adding 1.5 sticks of butter to anything--it's always the full 2 sticks for me. But when I recently came across this problem when pulling out my first batch of the delicious-sounding chocolate chip cookies from the gorgeous Clinton St. Baking Company Cookbook (after an "oh sh*t" sort of moment, since we're being honest), I was buoyed with courage from having recently received another brilliant book, entitled How to Repair Food , and decided that I would try to improvise.
Now, this wasn't highly technical, but I thought to myself: "OK, so I added too much butter. What if I added some extra flour?".
And so I added half a cup of flour, mixing only until incorporated.
And while I can't say that it is a definitive fix, you know what? In this case...it kind of worked. The cookies were not only perfectly palatable, but delightfully delectable--perhaps not as pretty as the original recipe, but I even felt comfortable sharing them.
...of course, that having been said, the recipe I'm sharing is for the "official" version, not my extra-buttery one.
...and also, of course, if you do add too much butter and have pancake-cookies, just sandwich them with frosting. You'd be amazed how much it fixes things.
