3 Simple Ingredients

That’s right, you only need THREE ingredients!

Peanut Butter– use creamy butter, Skippy and Jiff are classic brands. Don’t use crunchy peanut butter or reduced fat peanut butter, the cookies will be dry and crumbly.Sugar– basic white sugar does the trick!Egg– to add moisture and bind the ingredients together.

How to Make 3 Ingredient Peanut Butter Cookies

Preheat the oven and line a large baking sheet with parchment paper or a Silpat baking mat. In a large bowl, mix peanut butter, sugar, and egg together until creamy and smooth. You can use a stand mixer, hand mixer, or mix by hand. Scoop the cookie dough into balls, about 1 tablespoon per cookie, and place on prepared baking sheet. Flatten each ball with the back of a fork, making a criss-cross pattern. The cookies don’t spread in the oven, so you can put them close together on the baking sheet.Bake for 8 to 10 minutes or until edges are slightly golden. Don’t over bake. If it’s your first time making the recipe, check the cookies early to be safe. The cookies should be slightly golden around the edges, but still soft in the center. They will set up as they cool. Remove from the oven and let the cookies cool on the baking sheet for 3 minutes. Transfer to a cooling rack to cool completely.
