These cookies are made with a few pantry staples. All ingredients are gluten free and delicious!

  • Creamy peanut butter – Using creamy peanut butter creates the best consistency. Do not use natural peanut butter with the oil on top as the cookies will spread and possibly break apart. Standard creamy peanut butter like Jiff Natural or regular Jiff works best. Some other brands of natural peanut butter without the oil on top, like creamy MaraNatha works good too.
  • Granulated Sugar – The sugar adds the sweet caramelized flavor to the cookies.
  • Egg – Use fresh eggs and organic, when possible. This helps ensure the best consistency and flavor.

How to Make Peanut Butter Cookies

mixing together ingredients for peanut butter cookies in a bowl

First, combine the three ingredients together in a large mixing bowl. We love this inexpensive glass set of mixing bowls. Stir the ingredients until smooth.

Roll the dough into 1-inch balls with your hands and place on a lined baking sheet. The dough may be a little sticky and that’s okay. Just shape them into a small ball. They will smooth out while baking.

Next, flatten the cookies slightly with the bottom of a glass. Gently press down on the top of the cookies.

Use a fork to press a criss-cross pattern into each cookie. Then bake on a cookie sheet and allow to cook completely. They will harden more as they cool.

Expert Tips

  • This recipe yields crispy cookies. You can adjust cook time to make them softer or chewier.
  • To make them soft, reduce the cook time slightly to about 9 to 12 minutes. You can also make them thicker and softer by not pressing down so much with the glass prior to baking.
  • To make chewier cookies, press down on the glass more to make them thiner. A thiner cookie will create a chewier cookie.
  • Reduce the sugar: If you want to reduce the amount sugar, use 1 cup peanut butter and 3/4 cup sugar instead.
  • Don’t use crunchy peanut butter. It changes the consistency of the cookies.

Why do peanut butter cookies have fork marks?

Pressing with a fork helps create the best thickness so that the cookies cook evenly. A fork is a basic kitchen tool that everyone has in their kitchen so it makes the process easy.

Why are my cookies falling apart?

There are a few reasons why your cookies are falling apart. The wrong ratio of ingredients, such as too little sugar or peanut butter will make them fall apart. The wrong type of peanut butter may cause them to fall apart. Or using old eggs may create crumbly cookies.

How long do peanut butter cookies last?

These cookies will last up to 5 days in a sealed bag or container. You can freeze them for up to 3 months.

Why aren’t my cookies flattening?

Don’t skip the flattening step. Use the bottom of the glass and the fork to flatten. If you skip this step then your cookies may not flatten.
