One of Hermine's classics - a simple cookie dominated by chocolate and oatmeal - a combination that really never gets old or overdone.

  • 2 sticks unsalted butter
  • 1 cup packed dark brown sugar
  • 1 cup granulated sugar
  • 2 teaspoons vanilla
  • 1 teaspoon salt
  • 2 eggs
  • 1 teaspoon baking soda
  • 2 teaspoons water
  • 1 1/2 cups flour
  • 1 1/2 cups old fashioned rolled oats
  • 1 1/2 cups coarsely chopped toasted walnuts or pecans
  • 16 oz about 2 cups coarsely chopped bittersweet chocolate (I used high quality chocolate chips)


  • ln large bowl combine the butter, brown sugar, sugar, vanilla and salt. Beat with a spoon until fluffy - I did it by hand but a stand mixer would be great here.
  • Beat in the egg, baking soda and 2 tsp water.
  • Stir in the flour, oats, walnuts, and chocolate. Transfer to a bowl just large enough to hold the dough, cover and refrigerate until firm, about 4 hours or overnight. (I think you can skip this step if you want or just refrigerate for an hour or so. BUT, it is a great make-ahead dough if that helps with time management.)
  • Preheat oven to 350° regular or 325 convect. Line 2 baking sheets with silicone mats or parchment paper. Using 1-2 Tbsp of dough for each cookie, shape the dough into balls and space them out on the cookie sheet with 1.5 - 2 inches of space between each dough ball.
  • Bake for 10-12 minutes, until the cookies spring back when very lightly touched. Do not overbake or the cookies will dry out.
  • Cool on the sheets for 2 minutes then transfer to racks to cool. Repeat the baking procedure with cool baking sheets.
