Ingredients:

• 1 cup all-purpose or cake flour
• 1 1/2 cups walnuts, finely chopped
• 2 tablespoons granulated sugar
• 1 teaspoon vanilla extract
• 1 stick (113g) unsalted butter, at room temperature
• Pinch salt
• Powdered sugar, to coat (about 1 cup)

Cooking Instructions:

1. Make the dough:
   Mix all the dry ingredients—flour, walnuts, salt, sugar—in a large bowl. Add the vanilla extract. Add the butter in little pieces, and combine everything together with your (clean!) hands until the mixture looks like a coarse meal with nut bits in it.
2. Chill the dough:
   Chill the dough for at least 30 minutes in the fridge or up to overnight.
3. Preheat the oven:
   Preheat the oven to 300°F.
   Line a baking sheet with parchment or silicon baking mats.
4. Form the dough into balls:
   Form the dough into small balls no larger than a walnut and place on the cookie sheet, spaced at least an inch apart from each other.
5. Bake:
   Bake the cookies for 35 minutes.
6. Roll in powdered sugar:
   When cookies are still warm, but cool enough to touch, roll them in the powdered sugar. Set aside on a rack to cool completely. When cool, dust again in powdered sugar.
