Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Creamy Peanut Butter – The star of the show, giving the cookies their signature nutty flavor and rich texture. Use a classic creamy peanut butter (not natural or oily) for the best consistency.

Unsalted Butter – Adds richness and keeps the cookies soft and tender.

Brown Sugar – Provides sweetness and moisture for that soft, chewy texture.

Granulated Sugar – Balances the flavor and gives a slight crisp edge.

Eggs – Bind the dough and add structure while keeping it moist.

Vanilla Extract – Enhances all the flavors and adds a warm aroma.

All-Purpose Flour – Forms the base of the cookie dough for perfect structure.

Old-Fashioned Rolled Oats – Create a hearty chew and help balance the sweetness of the peanut butter.

Baking Soda – Gives the cookies a slight lift and keeps them light.

Salt – Brings out the flavors and balances the sweetness.

Optional Add-Ins: Chocolate chips, chopped peanuts, or a drizzle of melted chocolate on top.

Directions

1. Preheat the oven: Set your oven to 350°F (175°C) and line baking sheets with parchment paper.
2. Cream butter and sugars: In a large mixing bowl, beat together softened butter, brown sugar, and granulated sugar until light and fluffy (about 2–3 minutes).
3. Add peanut butter and wet ingredients: Mix in the peanut butter, eggs, and vanilla extract until smooth and creamy.
4. Combine dry ingredients: In a separate bowl, whisk together flour, baking soda, and salt. Gradually add this to the wet mixture until combined.
5. Fold in oats: Stir in the rolled oats until evenly distributed. If using chocolate chips or nuts, fold them in at this stage.
6. Scoop the dough: Use a cookie scoop or tablespoon to drop dough balls (about 1½ tablespoons each) onto the prepared baking sheets, spacing them about 2 inches apart.
7. Bake: Bake for 9–11 minutes, or until the edges are lightly golden but the centers still look slightly soft.
8. Cool: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

FAQs

Can I use natural peanut butter?

It’s best to use regular creamy peanut butter—natural varieties can make the dough oily and crumbly.

Can I make the dough ahead of time?

Yes, you can refrigerate the dough for up to 48 hours before baking.

Why are my cookies dry?

Overbaking or using too much flour can cause dryness—pull them out when the centers still look soft.

Can I use quick oats instead of rolled oats?

Yes, but the texture will be slightly less chewy and more delicate.

Can I make them gluten-free?

Use a gluten-free flour blend and certified gluten-free oats for a perfect substitute.

How do I make them thicker?

Chill the dough for 30 minutes before baking to prevent spreading.

What’s the best way to make them extra soft?

Do not overbake—remove them just as the edges turn golden and the centers are set.

Yes, scoop dough balls onto a tray, freeze until solid, then store in a freezer bag. Bake straight from frozen, adding 1–2 minutes to the bake time.

Can I add peanut butter chips?

Absolutely—they enhance the peanut flavor and add delicious pockets of creaminess.

Can I make them dairy-free?

Yes, use dairy-free butter or coconut oil as a substitute.
