Ingredients

• 1 cup unsalted butter
• 0.5 cups confectioners' sugar
• 1 teaspoon vanilla extract
• 2 cups all-purpose flour
• 1 cup chopped walnuts
• 0.25 cups confectioners' sugar , or as needed

Instructions

1. 1 Beat butter in large bowl until light. Beat in 1/2 cup confectioner's sugar and vanilla. Add flour and mix until just blended. Stir in nuts. Shape dough into a ball, then flatten into a disc. Wrap in plastic wrap and refrigerate until cold.
2. 2 Preheat the oven to 325 degrees F (170 degrees C). Line cookie sheets with parchment paper.
3. 3 Shape chilled dough into 1-inch balls. Place on the prepared sheets, spacing evenly.
4. 4 Bake in the preheated oven until firm and lightly colored, about 20 minutes.
5. 5 Sift 1/4 cup confectioners' sugar into a bowl. Transfer warm cookies to confectioners' sugar and roll gently to coat. Immediately transfer cookies to a resealable plastic bag, seal the bag, and let sit until cookies sweat and form an icing, about 5 minutes. Transfer to a wire rack and cool.
