  • 1 cup unsalted butter room temperature
  • ½ cup granulated sugar
  • ¼ cup powdered sugar
  • 1 large egg room temperature
  • ½ teaspoon vanilla extract
  • 2 cups all-purpose flour
  • ½ cup good cocoa powder Valrhona if available
  • 1 tablespoon cornstarch


  • Whisk dry ingredients (flour, cornstarch, and cocoa powder) together and set aside.
  • Cream butter and sugars with paddle attachment, on medium-low speed, until fluffy and pale in color (about 5 minutes).
  • Add egg and vanilla extract and mix on low speed until thoroughly combined. Scrape down the paddle with a spatula, and then continue to mix on low speed for another 30 seconds to ensure everything is fully incorporated.
  • Add dry ingredients, all at once, and mix on low speed just until dough starts to come together and no dry bits remain. Do not overmix.
  • Turn dough out onto cling wrap, tightly wrap, and refrigerate overnight (or for at least 4 hours).
  • Knead, roll, cut out cookies, and return to fridge or freezer until firm. Leave a couple inches between cookies.
  • Bake at 350°F for 15 minutes, rotate pan, and bake for another 1-5 minutes until edges are starting to darken in color.*
  • Remove cookies from oven and allow to cool on cookie sheet before handling.


  • Chocolate cookies are a little harder to tell when the edges are darkening, so you can quickly and gently press on the center of a cookie, and if they feel firm, they’re done. If you leave a dent, or they feel squishy, let them bake for a little longer.
  • The reason for adding 1-2 tablespoons of cornstarch to your dough is to prevent your cookies from shrinking or spreading during baking.
  • If making slice-and-bake cookies, split dough in half, roll into logs, wrap tightly in cling wrap or parchment paper, and refrigerate before slicing and baking.
