- Preheat oven to 350 degrees. In a mixing bowl, combine first six ingredients.
- In a stand mixer fitted with paddle attachment, beat butter and sugar on medium-high speed until fluffy, about 3 minutes. Beat in eggs and vanilla. Reduce speed to low and fold in flour mixture until just combined.
- Form dough into two (12-inch) logs that are 1½-inches in diameter. Wrap each with plastic wrap. Using your hands, square off sides of logs. Chill in refrigerator until firm, about 1 hour.
- Cut logs into ¼-inch-thick slices and arrange on two parchment-lined baking sheets. Bake two sheets on upper and lower thirds of oven for 10 to 12 minutes, switching pans’ positions halfway through baking. Transfer cookies to a rack to cool.
