Ingredients:
- 1 cup (250g) peanut butter
- 1 cup (200g) granulated white sugar
- 1 large egg
Instructions:
- Preheat your oven to 350°F (180°C). Line a large baking sheet with parchment paper or a Silpat mat to prevent sticking. Note: A preheated oven ensures the cookies set before the fat melts too much.
- In a medium mixing bowl, combine the peanut butter, sugar, and egg. Stir vigorously with a spatula or wooden spoon until the mixture transforms into a smooth, slightly shiny dough that pulls away from the sides of the bowl. Note: This takes about 60 seconds of solid stirring.
- Roll the dough into 1 inch spheres (approximately the size of a golf ball). Place them on the prepared baking sheet, spaced 2 inches apart. Note: Consistent size ensures they all finish cooking at the same time.
- Using the tines of a dinner fork, press a crosshatch pattern into each ball, flattening the cookie to approximately 1/2 inch thickness. Note: This increases surface area for better browning.
- Bake for 10 minutes, or until the edges are set and the bottoms are a deep mahogany color. Do not overbake. Note: They will look slightly underdone in the center, which is perfect.
- Allow the cookies to rest on the hot baking sheet for at least 5 minutes. This cooling period is essential for the structure to set before moving them to a wire rack. Note: Moving them too early will cause them to shatter.
- Check the underside of one cookie; it should be dark gold but not black.
- Transfer to a wire rack to finish cooling completely for maximum crispness.
