3/4 cup pecans, chopped
1/2 cup (1 stick, 112 g) unsalted butter, room temperature
1/3 cup (70 g) sugar
1 teaspoon vanilla extract
1/8 teaspoon salt
1 cup (140 g) all-purpose flour
1 Make cookie dough: With an electric mixer, beat the butter for about a minute. Add 1/3 cup sugar and beat until light, about 1 minute more. Beat in vanilla, salt, and flour, scraping down sides of bowl, just until dough comes together. Fold in pecans.
2 Roll into balls: Separate dough into 12 pieces; squeeze dough to shape into balls. Place, 3 inches apart, on a baking sheet.
3 Gently flatten with the bottom of a glass (reshape sides if necessary).
4 Bake at 350°F (175°C) until golden brown, rotating sheet halfway through, about 15 minutes. Cool cookies on a wire rack.
