Introduction
You get the best of both worlds with these cookies—chewy, hearty oats paired with the rich, satisfying flavor of peanut butter. They’re the perfect cross between a classic oatmeal cookie and a beloved peanut butter cookie, resulting in a treat that’s wonderfully soft in the center with just a bit of crispness at the edges. They are simple to make and always a crowd-pleaser.
Prep & Cook Time
- Prep Time: 15 minutes
- Cook Time: 12 minutes
- Total Time: 27 minutes
- Servings: 24 cookies
Ingredients
- 1½ cups all-purpose flour ((180g))
- 1 teaspoon baking soda
- ¾ teaspoon salt
- 1 cup unsalted butter (room temperature (227g))
- 1 cup creamy peanut butter ((255g))
- ¾ cup packed light brown sugar ((165g))
- ¾ cup granulated sugar ((150g))
- 2 large eggs
- 2 teaspoons vanilla
- 2½ cups old-fashioned rolled oats ((280g))
Instructions
- Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
- In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
- In a large bowl, using a hand mixer or stand mixer, cream together the room-temperature butter, creamy peanut butter, light brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.
- Beat in the eggs one at a time, mixing until fully incorporated after each addition. Then mix in the vanilla.
- With the mixer on low speed, gradually add the dry flour mixture to the wet ingredients, mixing just until no streaks of flour remain.
- Use a sturdy spatula or wooden spoon to fold in the old-fashioned rolled oats until they are evenly distributed throughout the dough.
- Scoop dough using a 1.5-tablespoon cookie scoop or a spoon, rolling into balls. Place them about 2 inches apart on the prepared baking sheets.
- Bake for 10-12 minutes, or until the edges are lightly golden and the centers look just set. The cookies will continue to firm up as they cool.
- Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- Thicker Cookies: For a thicker, softer cookie, chill the shaped dough balls for 30 minutes before baking.
- Fluffier Cookies: Slightly reduce the oats to 2 cups for a more cake-like texture.
- Fork-Press Method: For a classic peanut butter cookie look, lightly flatten each dough ball with the back of a fork, creating a criss-cross pattern before baking.
- Cookie Sandwiches: Once cooled, sandwich two cookies together with a dollop of extra peanut butter or a simple vanilla frosting.
Tips for Success
- Ensure your butter is truly at room temperature for proper creaming and a better cookie texture.
- Use a cookie scoop for uniformly sized cookies, which ensures even baking.
- Let the cookies rest on the hot baking sheet for 5 minutes after baking—this helps them set without becoming over-baked.
Storage & Reheating
Store completely cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the baked cookies for up to 3 months. To reheat, place a cookie in the microwave for 10-15 seconds to restore a warm, soft texture.
FAQ
Can I use quick oats instead of old-fashioned rolled oats?
Yes, but the texture will be slightly less chewy and more uniform. The cookies may also spread a bit less.
Why are my cookies spreading too much?
Your butter may have been too warm or melted. Ensure your butter is cool room temperature. You can also try chilling the dough for 30 minutes before baking.
Can I use natural peanut butter?
It’s not recommended for this recipe. Natural peanut butter is often oilier and can separate, leading to inconsistent texture and spread. Stick to a standard creamy peanut butter.
My dough seems dry. What happened?
This can happen if you overmeasured the flour. For best results, spoon the flour into your measuring cup and level it off.
How can I make these cookies gluten-free?
You can substitute the all-purpose flour with a 1:1 gluten-free flour blend. Ensure your oats are certified gluten-free as well.
Can I double this recipe?
Absolutely. Simply double all the ingredients. You may need to bake in batches to avoid overcrowding your oven.
