Coated in confectioners’ sugar, these buttery cookies look like little snowballs.
Preheat oven to 300 degrees F. Grind pecans in food processor to consistency of coarse meal. Set aside. With a mixer on medium speed, beat butter until soft. Blend in sugar, vanilla, and pecans. Carefully add flour and blend well. Coat hands with flour; roll dough into cherry-size balls. Place on greased baking sheet (or parchment paper). Bake until golden brown, about 45 minutes. While cookies are still hot, roll them in confectioners’ sugar. When cool, roll again. These cookies can be made up to 3 days in advance.
