Notes

For best results, follow the instructions above as written.
SUBSTITUTIONS
  • Peanut Butter: We recommend using creamy Jiff peanut butter or Jiff natural. You do not want to use crunchy peanut butter.
  • Sugar: If you want to reduce the amount sugar, use 1 cup peanut butter and 3/4 cup sugar instead. Do not use confectioners' (powdered) sugar.
  • Eggs: Use fresh eggs. To make it vegan, you can substitute an egg for a flax egg, which is made by mixing together 1 tablespoon flaxseed with 2 tablespoons water and letting it rest for 5 minutes.
MODIFICATIONS
  • Don't skip the flattening step.
  • To make them soft, reduce the cook time slightly to about 9 to 12 minutes.
  • To make chewier cookies, press down on the glass more to make them thiner.
STORAGE: Store cookies in an airtight container for up to 5 days.
FREEZING COOKIES: You can freeze the baked cookies for up to 3 months. Once the cookies are cookie, place the cookies on the cookie sheet into the freezer. Freeze until completely frozen, then transfer to a freezer safe bag or container. Warm them in the oven before serving, by baking in a 350°F oven for 5 minutes, or until warm.
MAKING DOUGH AHEAD: You can make the dough in advance, then wrap in plastic wrap and chill in the refrigerator for up to 2 days before baking. Or you can freeze dough and thaw when you are ready to bake. To freeze, wrap dough in plastic, store in a freezer safe bag in the freezer.
