How To Make 3-ingredient Peanut Butter Cookies

My 3 Ingredient Peanut Butter Cookie recipe is truly the easiest recipe you will ever make! You can whip this up so quickly and they taste delicious. This is also a great recipe to remember, made with just 1 cup of peanut butter, 1 cup of sugar, and 1 egg.

You mix all 3 ingredients together in a bowl, you roll the dough into balls and press them down and flatten them with the back of a fork.

Cookie Dough on a Baking Sheet

Bake these 3 ingredient cookies for 12-15 minutes. Even though the ingredients and prep time is cut by quite a bit, but none of the flavor or texture is lost in any way. I am a peanut butter fanatic so these are definitely at the top of my list for being a favorite.

Freshly Baked Peanut Butter Cookies

What is the best peanut butter to use when making peanut butter cookies?

You will want to use the basic creamy peanut butter that we all grew up on. I would not recommend using natural peanut butter that has the oil to mix in. The newer peanut butters will make the cookies too crumbly, so stick with the basics.

How to Store Peanut Butter Cookies

These cookies will last up to 5 days stored in an airtight container at room temperature.

Can You Freeze Peanut Butter Cookies?

YES! After you bake them, let them cool completely. Place them in an airtight container with a piece of parchment paper in between the layers. You can also place them in freezer bags.  Freeze for up to 3 months. When ready to serve, thaw overnight on the counter or in the fridge.

Cook: 10 mins
Total: 15 mins


  • 1 cup granulated sugar
  • 1 cup peanut butter

  • Using a wooden spoon, mix together the peanut butter, white sugar and egg until smooth.
  • Form dough into heaping tablespoons (about 3/4 inch). Then roll the dough ball in a small bowl of sugar, if desired, to coat the outside. Place on the baking sheet at least 2 inches apart, and then use a fork to flatten and form a cross pattern.
  • Bake for 10-15 minutes, until the cookies are just slightly browned on the bottom. Be careful not to over-bake. Remove and let cool on the baking sheet for 1 minute, then transfer to a wire rack to cool completely.
  • Serve and enjoy!

    Made these with three grandsons. Doubled the recipe. Used two bowls. One prepared the cookie sheets. Kept having each kid do a part and moved everyone around. They really loved the rolling dough into balls part. They were anxious to do their parts, had fun and after eating several, with milk, said ” We need to make these again.” It was a great time! Made about 3 dozen. They were different shapes and thicknesses, fork imprints were a little wonky (who cares?) but they were delicious!
