Preheat oven to 350 degrees Fahrenheit or 176 degrees Celsius. Place on a piece of parchment paper or silicone mat on baking sheet and set aside.
Combine egg, peanut butter, and sugar in a bowl by hand or with a stand mixer until smooth and creamy.
Scoop dough and roll into balls. The cookies do not spread much as they cook, so you can place them close together on the baking sheet. Use the back of a fork to press down on the cookies twice to make a crisscross pattern.
Bake the cookies for 8-10 minutes in preheated oven or until the edges just start to brown. Remove cookies from oven and let cool for 1-2 minutes before transferring to a cooling rack to cool completely.

Can You Use Natural Peanut Butter?

Natural peanut butter can be a little tricky. The cookies may spread too much which is why I use regular peanut butter.
I have tested the recipe with Justine’s natural peanut butter and it worked, but other brands may not. If you try another brand, be sure to stir the peanut butter really well so the oil is completely mixed in.

Tips!

Use an electric mixer to make the cookie dough. It’s a lot easier and it will also ensure your cookies have the right texture.
Don’t over bake the cookies. Keep an eye on them and as soon as they are set and starting to turn golden around the edges, take them out of the oven. If you over bake them, they will be crumbly.
Add chocolate chips or finely chopped nuts to change them up!
If you want a sugar coating, roll each cookie dough ball in granulated sugar before placing them on the baking sheet.
Or, for a twist, and a little flaky sea salt on top of each cookie before you bake them.

Storage

Room temperature: Store the cooled cookies in an airtight container and they will keep well for four days at room temperature.
Freezer: Once the cookies are completely cool, store them in a freezer bag or container. They will keep well frozen for up to three months. Thaw them at room temperature before serving them.
