Ingredients

  • 1 large egg: Acts as a binder to hold the cookies together, giving them structure.

  • 1 cup (100g) granulated sugar: Sweetens the cookies and helps achieve a slightly crisp edge.

How to Make It

Step 1: Prepare the Baking Sheets

Preheat your oven to 350°F (175°C) to ensure even cooking. Line two 18×13-inch baking sheets with parchment paper or silicone baking mats—these will prevent sticking and make for an easy cleanup.

Step 2: Beat the Egg

In a small bowl, beat the egg with a fork until the yolk and white are just blended. This will help the egg integrate smoothly with the other ingredients.

Step 3: Mix the Ingredients

Combine the beaten egg, peanut butter, and granulated sugar in a medium mixing bowl. Stir the mixture with a wooden spoon until it is thoroughly combined, ensuring that there are no streaks of egg or sugar left.

Step 4: Shape the Cookies

Using a medium cookie scoop or two spoons, portion the dough into 1 1/2 tablespoon-sized balls and place them on the prepared baking sheets, spacing them 2 inches apart to allow for spreading.

Step 5: Create the Crosshatch Pattern

Lightly grease the bottom of a fork’s prongs (optional) and gently press down on each cookie to flatten slightly. Turn the fork and press again to create the signature crisscross pattern. This step is not just decorative; it also helps the cookies bake evenly.

Step 6: Bake the Cookies

Bake the cookies one sheet at a time for 10 to 11 minutes, or until they are slightly puffed and the edges are golden brown. Let them cool on the baking sheet for 5 minutes to set before transferring to a wire rack to cool completely.

Recipe FAQs

Can I use a natural peanut butter for this recipe?

Yes, but be aware that natural peanut butter is often less stable and might make the dough a bit oily. Be sure to stir the peanut butter well before using.

Can I substitute the sugar for a different sweetener?

You can use brown sugar or a sugar substitute, but these will alter the texture and sweetness. Brown sugar will make the cookies softer, while sugar substitutes may affect the structure.

How should I store these cookies?

Store the cookies in an airtight container at room temperature for up to a week. To maintain their texture, it’s best not to refrigerate them.
