Cream the softened butter in a large mixing bowl until smooth and pale, about 2 minutes.
112 Grams Salted butter
Add the granulated sugar and brown sugar, then continue mixing for another 2 minutes until the mixture looks light and fluffy.
100 Grams Granulated sugar, 110 Grams Light brown sugar
Stir in the peanut butter, followed by the egg, mixing until everything is fully combined and smooth.
130 Grams Smooth peanut butter, 1 Large Egg
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
160 Grams Plain flour, ¾ Teaspoon Baking soda, ½ Teaspoon Baking powder, Pinch Salt
Add the dry ingredients to the peanut butter mixture and gently mix until just combined, stopping as soon as no dry flour remains.
Gather the dough into a flat disc, wrap it tightly, and refrigerate for at least 2-4 hours (or up to 24 hours). Chilling the dough helps the cookies hold their shape and improves the texture.
When ready to bake, preheat the oven to 190°C (375°F). Line or lightly grease your baking sheets if needed.
Scoop the chilled dough into balls about 3 cm (1¼ inches) wide and place them on the baking sheet, leaving space between each cookie.
Use a fork to gently press a criss-cross pattern on top of each dough ball.
Bake one tray at a time on the center rack for 9-11 minutes, until the edges are lightly golden but the centers still look soft.
Let the cookies rest on the baking tray for 1 minute before transferring them to a wire rack to cool completely. Repeat with the remaining dough.
Notes
Tips and Tricks
Soft centers: Remove the cookies while they still look slightly underbaked in the middle, they'll firm up as they cool.
Don't skip the chill: Chilled dough prevents spreading and gives you thicker, chewier cookies.
Perfect fork marks: Dip the fork in sugar before pressing to prevent sticking and add extra crunch.
Extra flavor: Use a high-quality peanut butter for the richest taste.
Storage: Store cooled cookies in an airtight container at room temperature for up to 4 days, or freeze for longer storage.
