Ingredients

1 cup granulated sugar
Small-grained sugar helps the cookies crisp slightly on the outside while creating those pretty cracks on top.
1 cup creamy peanut butter
Use a smooth, well-stirred creamy peanut butter for the best texture and even mixing. Natural peanut butter with separated oil may make the dough looser.
1 large egg
The egg binds the sugar and peanut butter and adds a bit of lift and chew to the cookies.

Step-by-step Instructions

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Tip: Line the sheet before you start mixing to keep the workflow smooth.
In a medium mixing bowl, combine the sugar, peanut butter, and egg. Stir until the mixture is smooth and well combined.
Tip: Use a sturdy spoon or spatula. If the peanut butter is very stiff, let it sit at room temperature for a few minutes.
Scoop about 1 tablespoon of dough and roll it into a ball. Place the dough balls on the prepared baking sheet, spacing them about 2 inches apart.
Tip: Wetting your hands lightly can prevent sticking while rolling.
Use a fork to gently press down on each ball, creating a crisscross pattern on the top. Press only once or twice so the cookies keep some height.
Bake in the preheated oven for 10 minutes, or until the edges are set and the tops look slightly cracked.
Tip: Avoid overbaking. The cookies will set more as they cool.
Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.

Tips, Storage & Variations

Practical tip: If your peanut butter is oily, stir it well first. If dough is too sticky, chill for 10 to 15 minutes and then scoop.
Avoid overmixing. Stir only until combined to keep cookies tender.
Storage: Store cooled cookies in an airtight container at room temperature for up to 4 days. Place a sheet of parchment between layers to prevent sticking.
Freezing: Freeze baked cookies in a single layer on a baking sheet until firm, then transfer to a freezer bag for up to 3 months. Thaw at room temperature.
Flavor variations using only the existing ingredients: Slightly increase sugar to 1 1/4 cups for a sweeter, crisper cookie, or reduce sugar to 3/4 cup for a less sweet, denser cookie. Another option is to slightly flatten the dough balls more for thinner, crisper cookies.

FAQ

Q: Can I use crunchy peanut butter instead of creamy?

Q: Can I make these without an egg?
A: This recipe relies on the egg for structure, so omitting it will change the texture significantly.

Q: How do I prevent cookies from sticking to the pan?
A: Use parchment paper or a silicone baking mat to prevent sticking and make cleanup easier.

Q: Can I make larger or smaller cookies?
A: Yes. Adjust baking time slightly for different sizes. Larger cookies need a bit more time, smaller ones less.
