Ingredients & Substitutions

These are the main ingredients and substitutions for 3 ingredient peanut butter cookies. Scroll down to the recipe card for full ingredients list and instructions.

For best results, use natural creamy peanut butter. Use peanut butter made from only peanuts and salt. Peanut butter with added oils or sugars will yield more dry cookies. If desired, substitute creamy cashew butter or almond butter. For a nut free option, use sunflower butter.

For the granulated sweetener, use white sugar, brown sugar or coconut sugar. If using brown sugar, use only ¾ cup packed brown sugar. Moreover, this will add a rich molasses flavor to these cookies.

Lastly, use one egg. I do not recommend make an egg free version.
