Ingredients

Gather your squad. This trio is so simple, you probably have everything in your pantry right now. The beauty is in its simplicity, but the quality of your ingredients really shines through here.

No hiding behind fancy extracts or complicated techniques.

  • 2 cups creamy peanut butter (not the natural, oily kind!)
  • 2 cups granulated sugar
  • 1/2 cup unsalted butter

That’s the whole party. See? I told you it was easy.

The peanut butter is the star, so use a good one you love to eat by the spoonful.

Step-by-Step Instructions

  1. Melt the butter and sugar. Combine the butter and sugar in a medium saucepan over medium heat. Stir constantly until the mixture comes to a gentle boil and the sugar is completely dissolved.

    This is the only “cooking” you’ll do, I promise.

  2. Mix in the peanut butter. Remove the pan from the heat and immediately stir in the peanut butter until the mixture is completely smooth and uniform. You’ll know it’s right when it looks like a glorious, shiny peanut butter river.
  3. Form the cookies.

    Drop tablespoon-sized portions of the mixture onto a baking sheet lined with parchment paper. You can use a cookie scoop for perfect rounds or just two spoons. Pro tip: if the mixture is too soft to handle, let it cool for just a minute or two.

  4. Let them set.

    Allow the cookies to cool and firm up at room temperature for about 30 minutes. They will transform from gloppy goodness to perfect, firm no bake 3 ingredient peanut butter cookies. Patience is a virtue, but not for long.
