¾cupunsalted butter, at room temperature (170 grams)
1 ½cupall-purpose flour(180 grams)
1 ½cupwalnuts, very finely chopped (180 grams) (See Notes)
About 1cuppowdered sugar(113 grams)
Preheat oven to 3505°F. Line a sheet pan with parchment paper or a silicone baking mat.
In the bowl of a stand mixer fitted with a paddle attachment, or in a bowl with a hand mixer, beat the butter and sugar together on medium high speed until creamy and pale in color, about 3-4 minutes. Add the vanilla extract. Add the flour, nuts and salt, and mix until just combined.
Shape the dough into rounded tablespoons and place on the prepared baking sheet, about 2 inches apart. Bake until cookies just begin to turn golden brown, about 15 minutes.
Let sit on the pan until cool enough to touch but still warm, then roll in powdered sugar. Let cool completely and then roll in powdered sugar again.
Note: You can use any variety of nut in place of the walnuts, such as pecans, pistachios, hazelnuts, etc.
