Ingredients

  • Main Ingredients
  • 2 large egg whites room temperature preferred
  • Scant 1 cup granulated sugar approximately ¾ cup plus 2 tablespoons
  • 3 cups finely ground walnuts about 12 oz whole walnuts
  • 1 teaspoon vanilla extract
  • For the Topping
  • Powdered sugar confectioners' sugar for dusting

Instructions

  • Step 1: Prepare the Walnuts
  • Place whole walnuts in a food processor
  • Pulse in short bursts (10-15 times)
  • Grind until consistency resembles fine breadcrumbs or almond meal
  • Walnuts should pinch together slightly between fingers
  • Do NOT over-process or they'll turn into walnut butter
  • Stop before oils are released
  • Set aside ground walnuts
  • Step 2: Whip the Egg Whites
  • Ensure mixing bowl and beaters are completely clean and dry
  • Add 2 egg whites to the bowl (no trace of yolk)
  • Beat on medium speed with electric mixer
  • Continue until whites begin to foam and turn white
  • Gradually add sugar, 1 tablespoon at a time
  • Keep beating while adding sugar
  • Continue beating for 3-5 minutes total
  • Beat until stiff, glossy peaks form
  • Peaks should stand straight up when beaters are lifted
  • Step 3: Fold in Walnuts and Vanilla
  • Add 1 teaspoon vanilla extract to whipped egg whites
  • Fold gently to incorporate vanilla
  • Add all 3 cups ground walnuts at once
  • Use rubber spatula to fold gently
  • Cut down through center, sweep along bottom, bring up and over
  • Rotate bowl a quarter turn and repeat
  • Continue until walnuts are evenly distributed
  • Work gently to avoid deflating egg whites
  • Dough should be thick and sticky but hold together
  • Step 4: Shape the Cookies
  • Preheat oven to 350°F (180°C)
  • Line baking sheet with parchment paper or silicone mat
  • Use spoon or small cookie scoop (1-1.5 tablespoons)
  • Drop portions of dough onto prepared sheet
  • Space cookies about 2 inches apart
  • Optional: Wet fingers slightly and shape into neater rounds
  • Dough will be sticky - damp fingers prevent sticking
  • Step 5: Bake to Perfection
  • Place baking sheet in center of preheated oven
  • Bake for 13-15 minutes
  • Watch carefully during last few minutes
  • Cookies are done when lightly golden on edges and top
  • Surface should have slightly cracked appearance
  • Should feel set when gently touched but still soft
  • Check at 13 minutes - if golden and set, they're done
  • If pale and wet, bake 1-2 more minutes
  • Do not overbake or they'll be too hard and dry
  • Step 6: Cool and Finish
  • Remove cookies from oven
  • Let cool on baking sheet for 5 minutes (crucial step)
  • Do not move cookies before 5 minutes or they may break
  • After 5 minutes, transfer to wire cooling rack
  • Let cool completely
  • Once cool, place on serving plate
  • Dust generously with powdered sugar using fine-mesh sieve
  • Serve and enjoy
