The New York Times had an article about chocolate chip cookies today (
Perfection? Hint: It’s Warm and Has a Secret), and I couldn't resist commenting.
Then I realized I'd left a few points out, so I edited it a little before posting it here.
I use the traditional Toll House recipe with a few modifications:
1) double the amount of vanilla extract from one to two teaspoons (you can't ever go wrong with vanilla)
2) halve the amount of chips, or even reduce it to 1/3 of a bag; using a whole bag produces a cookie with an overpowering taste of chocolate. The real delight of a chocolate chip cookie is in the *balance* of flavors; if you just want chocolate, bake a chocolate cookie instead!
I believe that Nestle recommended using a full 12-oz bag of chips for the obvious reason, i.e. to sell more chips.
3) Instead of using 3/4 cup granulated white sugar and 3/4 cup brown sugar, I use 1 & 1/4 cups dark brown sugar and 1/4 cup granulated sugar.
I've seen a variation in which a package of instant vanilla pudding is added to the dry ingredients (flour, etc.) - oddly enough, in cookies I bought from a Mennonite store (for some reason I thought they'd avoid artificial ingredients). The result was a chewier and somewhat moister cookie. I tried baking them that way myself, but the difference didn't seem to be enough to make the extra cost and effort worthwhile. So I no longer use pudding mix in the recipe.
Once, though, I couldn't find vanilla pudding mix and substituted chocolate devil's food pudding mix. To my amazement, that little package turned the entire batch of cookies a rich, deep chocolate. They were quite good, although not as good as a well-made traditional cookie.
Since my baking time is limited these days, I often make the cookies into chocolate chip cookie bars instead. I use the standard recipe (with the vanilla and chip modifications above) and spread it into a buttered double-hulled 13x9 baking pan (it has two layers of metal separated by air, which greatly reduces the chances of burning). Minutes after I take it out of the oven I seal the pan with a layer of aluminum foil; this traps moisture in the bars.
The result is a very moist bar. So far everyone I know who has tried one has found them irresistible; they're positively addictive (I call them the crack of the baking world). I'm looking forward to trying the refrigeration trick, to see if that makes them even better!
