Ingredient Info and Substitution Suggestions

PEANUT BUTTER – We are using peanut butter powder in these cookies, which is lower in fat and calories compared to spreadable creamy peanut butter. It’s reconstituted with the addition of water, which will also help thicken the peanut butter dough into something more malleable. If preferred, you can substitute with 5 Tablespoons of creamy peanut butter instead of the powdered version. You will not need to add water if doing so.

SUGAR – For the granulated sugar substitute I would recommend Allulose or Swerve. You can also experiment with Stevia, erythritol, or monk fruit sweetener though I have not tested them myself in these cookies.
