These genius 3 ingredient peanut butter cookies are magic! Just a handful of ingredients make one dreamy easy cookie recipe.


  • 1 large egg (or flax egg for vegan)
  • 1 cup creamy peanut butter*
  • 1 cup light brown sugar (or granulated sugar)
  • Optional: flaky sea salt for topping, 1 teaspoon vanilla extract (add with the sugar)


  1. Preheat the oven to 350 degrees Fahrenheit. Line 2 baking sheets with parchment paper.
  2. Whisk the egg, then whisk in the peanut butter and brown sugar until a smooth dough forms. Chill for 15 minutes.
  3. Make 1 1/2 tablespoon-sized balls (using a size 40 cookie scoop, if you have it) and place them onto the 2 baking sheets, 5 cookies per sheet and evenly spaced about 2-inches apart. Roll the balls between your hands to make them as spherical as possible: if the dough is very sticky, lightly oil your hands to make it easier to roll*. 
  4. Use a lightly oiled fork to flatten the balls and make a criss-cross pattern (it’s helpful to dip the fork into a small bowl of water before each one to prevent sticking).
  5. Top the cookies with a small sprinkle of flaky salt if desired (oops, 4th ingredient!).
  6. Bake 8 to 10 minutes until lightly browned on the bottom but still soft. Cool completely before eating. Store at room temperature in a cookie tin for up to 1 week, or freeze for up to 3 months.


*The consistency of the dough will vary based on the peanut butter brand. A thinner, creamier peanut butter will yield a stickier dough.
