Why We Love This
With so few ingredients, it is easy to enjoy homemade cookies in minutes and they are gluten-free. The preparation is minimum, and they don’t take long to cook. You don’t even need all purpose flour, vanilla extract or any other common ingredients.
You can mix the simple ingredients by hand without an electric mixer. I don’t even use my stand mixer.
The peanut butter flavor shines through and tastes rich and decadent. I have been making this recipe for years and it never disappoints.

Ingredients

- Peanut Butter. Creamy peanut butter will give the cookies the smoothest taste and texture. I don’t recommend natural peanut butter because it tends to separate.
- Granulated Sugar. Just plain white sugar.
- Egg. I recommend a large egg at room temperature.
Variations and Additions
- Sprinkle Sugar. Before the cookies go in the oven, sprinkle the tops with granulated sugar.
- Chocolate Chips. Mix in ½ cup chocolate chips into the dough. You can use milk chocolate, dark chocolate, or semi-sweet chocolate chips.
- Melted Chocolate. Drizzle melted chocolate on top and sprinkle sea salt. Another option is to dip the cookies into melted chocolate.
- Cinnamon Sugar. Roll the dough balls in a cinnamon sugar mixture before baking.
Step By Step Instructions
- Step 1. Go ahead and preheat the oven to 350 degrees.

Step 2. Then line a baking sheet with parchment paper.

Step 3. Next, use a mixing bowl to combine peanut butter, sugar and egg.

Step 4. Combine until smooth. I used a wooden spoon.

Step 5. Shape the cookie dough into balls. I used a cookie scoop to quickly form the dough into 1 inch balls. Place on the prepared baking sheet. Spread the dough balls about 1 inch apart to allow room for spreading.

Step 6. Make a criss cross pattern using a fork on each cookie. This step will flatten the cookies and leave a pretty design. Allow to bake for 8-10 minutes until the edges of the cookies are set.

Step 7. Finally, let the cookies cool 5 minutes on the baking sheet and then move to a wire rack to cool completely.
Storage
Store inside an airtight container up to 5 days. Place a piece of bread inside the container to keep the cookies soft.
I like to keep cookie dough in the freezer. Learn How to Freeze Cookie Dough.

Pro Tips
- Peanut butter. Creamy peanut butter will give the cookies the smoothest texture. You can substitute with crunchy peanut butter if desired.
- Don’t overbake. The cookies will continue to set as they cool.
- Cool on baking sheet. It’s important to let the cookies cool for 5 minutes on the baking sheet before moving. They are really soft when they come out of the oven and moving too soon will make them crumble.
- Criss Cross Pattern. The cookies don’t spread much on their own. The criss cross pattern helps to flatten them for even baking.
