Butter Walnut Cookies

  • Prep Time: 0 hours
  • Cook Time: 0 hours
  • Total Time: 0 hours
  • Yield: about 24 cookies 1x


  • 1 cup all-purpose flour
  • 1 tablespoon cornstarch
  • big pinch of salt
  • 1/4 teaspoon baking powder
  • 3 tablespoons packed brown sugar
  • 1 1/2 cups finely chopped walnuts
  • 1 teaspoon pure vanilla extract
  • 1/2 cup (1 stick) unsalted butter, softened
  • 2 cups powdered sugar


  1. Place a rack in the upper third of the oven and preheat oven to 325 degrees F. Line a baking sheet with parchment paper and set aside. Place powdered sugar in a medium bowl and set aside.
  2. In a medium bowl, stir together flour, cornstarch, salt, baking powder, brown sugar, and walnuts.
  3. Stir in the vanilla extract. This might feel weird but just throw it in and stir.
  4. Add the butter and use a spoon to work the butter into the dry ingredients. Use your hands to mix the dough until it’s a coarse meal with lots of nut bits.
  5. Press heaping tablespoons of dough into walnut-sized balls and place an inch apart on the prepared baking sheet.
  6. Bake for 25 to 27 minutes. The cookies won’t brown very much but will appear to be dry on the outside and will feel fairly firm to the touch.
  7. Remove from the oven and allow to cool for 5 minutes before placing in powdered sugar bowl to coat. Coat generously in powdered sugar.
  8. Store in an airtight container at room temperature for up to four days.
