Recipe Tips

  • A combination of brown sugar and white granulated sugar is ideal. White granulated sugar helps the cookies spread while baking. Using more brown sugar than white granulated gives you a softer, moister, and thicker cookie.
  • Use a cookie scoop to portion out the dough.
  • After flattening the balls with a fork, use your fingers to reshape the edges into thicker/taller discs because the thicker the disc, the thicker the baked cookie.
  • Flour the fork before each criss-cross (or use a little granulated sugar). Otherwise, the fork will tend to stick, and you’ll lift the cookies and make a mess. 
  • Chilling the dough balls for a few hours will help them maintain their shape and not overly spread when in the oven.
  • Bake these until just done for softer cookies or longer for crunchy ones. 

Variations on Peanut Butter Cookies

Whether you want a classic criss-cross cookie or cookies with some extra flair, this soft-baked peanut butter cookie is the ideal base recipe for many variations. Here are a few ideas:

  • Swap out the peanut butter for another nut butter like almond butter or cashew butter.
  • Add some chocolate chips, caramel chips, cinnamon chips, or butterscotch chips.
  • Add chopped pretzels or crushed potato chips for a sweet and salty treat.
  • Top with a few crushed peanuts, walnuts, pecans, or almonds.
  • Drizzle the baked cookies with melted chocolate.
  • Use brown sugar for 3 ingredient peanut butter cookies with brown sugar.
  • Substitute the sugar with granular Swerve sweetener.
  • Use ground flaxseed as a binder instead of an egg.
  • Roll the cookie dough balls in sugar before pressing them with a fork.
  • Add a Hershey’s Kiss. Leave the dough balls as balls and roll them in granulated sugar. As soon as they come out of the oven, press in a Hershey’s Kiss (out of the wrapper, of course). 
  • Make cookie sandwiches with a peanut butter filling. Here are the ingredients:
    • 1¼ cups creamy peanut butter
    • 6 tablespoons unsalted butter, room temperature
    • 1¾ cups powdered sugar
    • 4 to 6 tablespoons heavy cream
    • 1½ teaspoons vanilla extract

3 Ingredient Peanut Butter Cookies Recipe Frequently Asked Questions

What kind of peanut butter works best?

If you want a soft cookie that stays mostly intact, use creamy. Go with chunky if you like a nice crunch and texture in your cookies. 

Can you use natural peanut butter?

Yes, but the natural brands (the ones that separate) give you cookies with a grittier texture that tend to spread too much. That said, if there is a natural brand of peanut butter that works for you, use it.

Can you make this recipe ahead of time?

Yes, you can make the dough up to 3 days in advance. However, the fats in the peanut butter will solidify in the fridge, so the dough needs to return to room temperature to make it easier to work with.

How to Serve Peanut Butter Cookies

Of course, a cookie with your coffee or tea is delightful and these cookies are super delicious dunked in milk! Here are some other ideas you may not have thought of:

How to Store Leftover Baked Cookies

Place in an airtight container for up to 5 days. 

Stack them with sheets of parchment paper between cookies in an airtight container in the freezer for up to 3 months. When you want to eat the cookies, allow them to thaw to room temperature.

How to Store Unbaked Cookie Dough

Refrigerate unbaked cookie dough with plastic wrap pressed against the dough for up to 3 days.

To freeze cookie dough, line a sheet-pan with foil and add the dough balls. Press with a fork to make a cross-hatch pattern, then freeze until the dough is solid. Place in an airtight container in the freezer for up to 3 months. Add a few extra minutes of baking time.

    This is the recipe I have been using for years but I also add 1 tsp. vanilla. After these are baked, you can’t tell the difference in these and the pb cookies that have all the other ingredients. This is so easy that my grandson loves to help make them. I have also used these and without making the # mark, when they are done I press a hershey kiss in the center. Can’t ask for a better or easier pb cookie recipe.

  2. Cindy

    This is my extended family’s favorite cookie with this addition:
    Instead of making the # with a fork, bake the cookies in 1" balls until golden (~8 minutes) then while still on cookie sheet, press an unwrapped Hershey’s Kiss into the center. Cool then transfer to plates and refrigerate until Kiss is hard.

  3. Billy

    These were great for a quick snack, but I did change something. I used a small amount of oatmeal and a few random spices.

  4. Micah

    Just tried this recipe. Very easy to do and takes almost no effort. On the other hand, the cookies aren’t that great. They’re very crumbly and mediocre. If you want a quick fix of peanut butter cookies, this recipe is spot on. If you want a really good peanut butter cookie, keep looking.
