Ingredients
Method
- Preheat oven to 350°F (175°C). Beat butter, peanut butter, and both sugars until light and fluffy, about 2 minutes.
- Mix in egg and vanilla until just combined.
- Whisk flour, baking soda, baking powder, salt, and cornstarch. Stir into wet mixture until no streaks remain.
- Scoop into 1 1/2-tablespoon balls, roll, and place on parchment-lined sheets. Press with a sugared fork in a crosshatch pattern. Bake 10 to 12 minutes until edges are golden and centers soft.
- Cool on the sheet for 5 minutes, then transfer to a rack. Serve warm or at room temperature.
Notes
If you’re using natural peanut butter, add 1 extra tablespoon of flour to prevent excessive spreading. Store baked cookies with a slice of bread to keep them soft.
