Ingredients
Method
- Stir the flour, baking soda, and salt together in a medium bowl until evenly blended.
- Beat the softened butter on high speed until smooth, then add both sugars and continue beating until pale and fluffy.
- Add the egg and extra beaten egg and mix until fully incorporated, scraping the bowl, then blend in the peanut butter and vanilla until uniform.
- Pour the dry mixture into the bowl and mix on low speed just until a soft, creamy dough forms, then cover and refrigerate for 1 to 2 hours to firm up.
- Set the oven to 350°F (177°C) and line large baking sheets with parchment paper or silicone mats.
- Place the rolling sugar in a small bowl, portion the chilled dough into rounded scoops, roll each in sugar, arrange on the trays, press a crisscross pattern with a fork, and gently nudge the edges back into a thick round.
- Bake until the edges look set and barely golden while the centers stay pale and soft, about 11 to 12 minutes.
- Let the cookies rest on the hot tray for 5 minutes, then move them to a rack to cool completely and finish setting.

Notes
Chilling the dough is the secret to keeping these cookies thick and tender. They’re perfect slightly warm with a glass of milk or tucked into a lunchbox the next day.
