Flavor varieties

peanut butter, egg, sugar.

This peanut butter cookie recipe is amazing, but if you’re like me and can’t leave great things alone, I have a few suggestions below on how to take them up a notch.

  • Swap the regular sugar with brown sugar for a chewier texture.
  • Stir in 1/2 cup chopped unsalted peanuts for extra crunch.
  • Add one teaspoon of vanilla extract to enhance flavor.
  • Sprinkle the flattened cookies with sea salt for a sweet, salty flavor combo.
  • Stir mini chocolate chips into the dough or dip the baked cookies in melted dark chocolate after they’ve cooled.

How to make flourless peanut butter cookies

making three-ingredient peanut butter cookies.
  • Combine the peanut, sugar, and egg in a large bowl.
  • Use a small ice cream scoop to portion out the dough for uniform sizes. Roll in the palm of your hands into balls to smooth and even the baked edges.
  • Press down on the dough with the tines of a fork to flatten it and create a criss-cross pattern.
  • Bake until the edges are lightly browned, but the centers are soft. Remove from the heat, let cool slightly, then transfer to a wire rack to cool completely.

Quick tips

If the dough is too soft to hold its shape, refrigerate it for a few minutes to chill and firm up.

Storage instructions

  • Allow the cookies to cool completely, then transfer them to an airtight container or a resealable bag. Store at room temperature for 2 to 3 days.
  • To store longer, arrange in a single layer on a baking sheet and freeze. Transfer to a resealable bag when firm, letting as much air out as possible. Freeze for up to 3 months.
