Oatmeal Chocolate Chip Cookies

Position racks in upper and lower thirds of oven; preheat to 350°F. Line 2 baking sheets with parchment paper.

Whisk oats, whole-wheat flour, all-purpose flour, cinnamon, baking soda and salt in a medium bowl. Beat tahini and butter in a large bowl with an electric mixer until blended into a paste. Add granulated sugar and brown sugar; beat until well combined. Beat in egg, then egg white, then vanilla. Stir in the oat mixture until just moistened. Stir in chocolate chips and nuts.

With damp hands, roll 1 tablespoon of the dough into a ball, place on a prepared baking sheet and flatten until squat, but don't let the sides crack. Continue with the remaining dough, spacing the flattened balls 2 inches apart.

Bake the cookies, switching pans back to front and top to bottom halfway, until golden brown, about 16 minutes. Cool on the pans for 2 minutes, then transfer to a wire rack to cool. Let the pans cool for a few minutes between batches.
