Step-by-Step Instructions
My process begins with the most important step: browning the butter. I melt one stick of the butter in a light-colored saucepan over medium heat. I swirl the pan constantly, watching as it foams, crackles, and then turns a beautiful golden amber with tiny brown bits at the bottom. The second I smell that nutty, toasty aroma, I pour it immediately into a heatproof bowl to stop the cooking. I let it cool for about 20 minutes until it’s solid again but still soft. This brown butter is the secret to the cookies’ deep, caramel-like flavor. While it cools, I let the other stick of butter soften at room temperature.
In the bowl of my stand mixer, I combine the softened butter and the cooled brown butter. I beat them together on medium speed for a full 2-3 minutes until they are perfectly creamy and pale. Then, I gradually add the 1 cup of granulated sugar, beating for another 2 minutes until the mixture is light and fluffy. This step incorporates air, which is key for the perfect texture. I scrape down the sides of the bowl, then beat in the egg and vanilla extract until just combined. I can already smell the incredible fragrance coming from the bowl.
In a separate bowl, I whisk together the flour, baking soda, cream of tartar, and salt. The cream of tartar is the unsung hero here; it reacts with the baking soda to give the cookies a slight lift and, more importantly, contributes to that signature crisp, crackly surface. I add the dry ingredients to the wet mixture in two additions, mixing on low speed just until the flour disappears. The dough will be soft and slightly sticky, which is perfect. I cover the bowl and chill the dough in the refrigerator for at least 30 minutes. This firms up the butter, preventing the cookies from spreading too much and making the dough easier to handle.(See the next page below to continue…)
