3 Simple Ingredients!

  • Peanut butter
  • Sugar
  • Egg

How to Make 3 Ingredient Peanut Butter Cookies

How to make 3 ingredient peanut butter cookies.
  • MIX. Mix together the ingredients in a medium bowl. If the dough is too sticky, feel free to chill it in the fridge for 10 to 20 minutes.
  • ROLL. Use a medium cookie scoop or your hands to roll the dough into balls. You should end up with 12 (1″) balls. Then roll the dough ball into more granulated sugar and place on a lined baking sheet. Press down twice with a fork, creating a cross pattern.
  • BAKE. Bake in oven at 350°F for 8 to 10 minutes, or until the bottoms are very lightly browned.

  • Don’t press the cookie with a fork and add a Hershey Kiss to the top instead. You can also add a Reese’s cup, like I did with these peanut butter cup cookies.
  • Dip half the cookie in melted chocolate.
  • Use brown sugar in place of granulated sugar.
  • Use baking splenda if you want less sugar.
  • Add a teaspoon of vanilla for even more flavor.

Helpful Tips

  • Chill the dough: If the dough feels too sticky to work with, chill it in the fridge for 10 to 20 minutes prior to scooping.
  • Press with a fork. Because there’s no flour or butter, these cookies don’t spread. After you roll the dough into balls, make sure to press down on them with a fork so that they flatten. This helps them cook evenly and gives them a circular shape.
  • Don’t over bake. Once the edges and bottoms are lightly golden, remove them from the oven. They’ll continue to firm up once they’re removed from the oven and begin cooling.
