Chocolate Chip Cookies — From Ruth Wakefield’s 1938 Toll House Accident to a Brown-Butter Modern Bake

Transcript

Anna Park: Forty grams of brown butter, smelling like toasted hazelnut, is whisking into a Pyrex bowl of vanilla cookie dough. Three feet to my right, a sheet pan of just-baked chocolate chip cookies — golden caramelized edges, lakes of molten dark chocolate, centers still gooey — came out of a one hundred ninety Celsius oven exactly nine minutes ago. The chocolate chip cookie was invented in nineteen-thirty-eight in Whitman, Massachusetts. Tonight we take it apart, ingredient by ingredient. I am joined by Chef Maggie O'Sullivan of Quincy, and Chef Brendan McCarthy of Cambridge, Massachusetts.

Chef Maggie O'Sullivan: Now honey, listen — Ruth Wakefield, nineteen-thirty-eight, the Toll House Inn in Whitman, Massachusetts. She is making butter drop cookies for her guests. She chops up a bar of Nestle semi-sweet chocolate and folds it into the dough, expecting it to melt like baking chocolate would. It does not. It holds its shape. Those first cookies come out with discrete pockets of half-molten chocolate, and the chocolate chip cookie is born. By nineteen-forty Nestle prints her recipe on every Toll House label and pays her one dollar plus a lifetime supply of chocolate. Every cookie you ate traces back to that accident in Whitman.

Chef Brendan McCarthy: Kid, the single thing that separates a great chocolate chip cookie from a good one is brown butter — beurre noisette. Take two hundred twenty-five grams, sixteen tablespoons, of unsalted butter in a stainless steel skillet — never nonstick, you cannot see the color change. Medium heat, one hundred forty Celsius, two eighty-five Fahrenheit. Butter melts. Foams. Foam subsides. Whisk constantly. After six minutes the milk solids on the bottom turn deep amber and the kitchen smells like toasted hazelnuts. Pour into a heat-safe bowl, every speck of brown bits included. Cool ten minutes — liquid but no longer hot.

Chef Maggie O'Sullivan: Honey, into the cooled brown butter you whisk two hundred grams, one cup packed, of dark muscovado or dark brown sugar — for moisture and butterscotch — and one hundred grams, half a cup, of granulated white sugar for crisp edges. Whisk one full minute until it looks like wet sand. Add one large egg, sixty grams, plus one additional yolk, twenty grams. Whisk forty-five seconds until pale and ribbon-thick. Stream in twelve grams, one tablespoon, of vanilla extract — and if you have it, one tablespoon of bourbon for depth. Whisk thirty seconds more. The mixture should look glossy and emulsified, not separated.

Chef Brendan McCarthy: Now the dry, kid. In a separate bowl whisk two hundred eighty grams, two and a quarter cups, of all-purpose flour with four grams, three-quarters teaspoon, of baking soda — never baking powder for this cookie — and five grams, one and a quarter teaspoons, of fine sea salt. Thirty seconds vigorous whisking to distribute. Tip the dry into the wet in three additions, folding with a silicone spatula, never a stand mixer. Stop the instant you no longer see flour streaks — overwork develops gluten and gives you tough cookies. The dough is shaggy and slightly tacky now, exactly right.

Chef Maggie O'Sullivan: Now honey, the chocolate. Bagged chips are pre-tempered and won't melt right — you want CHUNKS. Take three hundred grams, ten and a half ounces, of high-quality chocolate, chopped by hand on a board with a serrated knife. Use half dark seventy-percent for depth, half milk chocolate for caramel sweetness. Chop irregularly — some big half-inch shards, some small dust. The dust melts into the dough giving you streaks; the shards stay as molten pools. Fold into the dough in two additions. Reserve a handful to press onto each cookie top after portioning for that bakery-puddle look.

Chef Brendan McCarthy: Baby — and this is the step nobody wants to hear — the dough rests in the fridge a minimum of twenty-four hours. Seventy-two is better. Flour fully hydrates, the sugars dissolve into the moisture, cookies bake up deeper-flavored and less cakey. Press the dough flat into a parchment-wrapped disk, cover tight, refrigerate. When ready: portion with a number-twenty disher, a sixty-milliliter cookie scoop — about seventy grams of dough each. Place six per half-sheet pan, three rows of two, well-spaced. They spread aggressive. Press a few reserved chocolate shards onto each top, finish with flaky sea salt.

Chef Maggie O'Sullivan: Now we bake, honey. Preheat the oven a full half hour at one hundred ninety Celsius, three hundred seventy-five Fahrenheit, middle rack. Sheet pan lined with parchment, not foil. Bake exactly twelve minutes — edges golden brown, centers still pale and visibly underdone. Rotate the pan at six minutes. Pull immediately. Bang the pan once on the counter to deflate the centers — that classic bakery wrinkle. Rest on the pan ten minutes; carryover heat finishes cooking. Sins: room-temp butter, no chill, chips not chunks. Variations: rye flour, espresso powder, or my grandmother's trick — one tablespoon dark rum in the dough.

Anna Park: Three takeaways. First, BROWN your butter — six minutes in a stainless skillet over medium heat until it smells like toasted hazelnut and the milk solids on the bottom go deep amber. Second, REST the dough — twenty-four hours minimum, seventy-two is better, parchment-wrapped in the fridge. Hydration is everything. Third, CHOP a bar of high-quality chocolate, do not use bagged chips — half dark seventy-percent, half milk chocolate, irregular sizes from dust to half-inch shards. One hundred ninety Celsius for twelve minutes, bang the pan, rest ten. My deepest thanks to Chef Maggie O'Sullivan and Chef Brendan McCarthy.
