Step 1

Preheat your oven to 350°F (175°C).

Step 2

Line a baking sheet with either parchment paper or a silicone mat.

Step 3

In a large bowl, mix the peanut butter, sugar, and room temperature egg together. Use a fork, whisk, stand mixer, or electric mixer to mix until all the ingredients are well combined and a thick dough has formed.

Step 4

Using a cookie scoop or a measuring spoon, scoop tablespoon-sized portions of the dough and roll them into balls using the palm of your hands.

Step 5

Place the cookie dough balls on the baking sheet that you prepared, leaving about 2 inches of space between them.

Step 6

Use the back of a fork to create a criss-cross pattern on the cookies if you want. The fork marks are optional.

Step 7

Bake the cookies in the preheated oven for 10 to 15 minutes or until the edges are lightly golden.

Step 8

Remove the cookie sheet from the oven and let the cookies cool on the sheet for 5 minutes.

Step 9

Transfer them to a wire rack so they can cool completely.
