Ingredients
  

  • 1 cup peanut butter (smooth or crunchy)
  • 1 cup sugar (granulated or a mix of granulated and brown sugar)
  • 1 large egg
  • 1 tsp baking soda

Optional Add-ins:

  • ½ cup chocolate chips
  • ¼ cup chopped peanuts
  • Sea salt (for sprinkling)

Instructions
 

Preheat the Oven:

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

Mix the Dough:

  • In a mixing bowl, combine peanut butter, sugar, egg, and baking soda. Mix until smooth and well combined.

Shape the Cookies:

  • Roll the dough into 1-inch balls and place them on the prepared baking sheet, spacing them about 2 inches apart.

Create the Criss-Cross Pattern:

  • Use a fork to press down on each dough ball, creating a criss-cross pattern.

Bake:

  • Bake for 10–12 minutes, or until the edges are golden. The cookies will be soft when they come out of the oven but will firm up as they cool.

Cool and Serve:

  • Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.

Notes

  • Pro Tip: For a chewier texture, use half granulated sugar and half brown sugar.
  • Storage: Store cookies in an airtight container at room temperature for up to 4 days.
  • Freezing: Freeze unbaked dough balls on a baking sheet, then transfer to a freezer-safe bag. Bake directly from frozen, adding 2–3 minutes to the baking time.
