Ingredients You’ll Need for Delicious Peanut Butter Oatmeal Cookies
Here are all the ingredients you’ll need to bake a batch of these irresistible peanut butter oatmeal cookies. I’ve included some of my favorite brand recommendations with affiliate links for your convenience:
Unsalted Butter, softened (1 cup or 2 sticks): I prefer Land O'Lakes Unsalted Butter for its consistent quality.
Granulated Sugar (¾ cup): Adds sweetness and helps with browning.
Brown Sugar, packed (¾ cup): Provides moisture and a chewy texture. I recommend Domino Golden Sugar Brown Sugar.
Creamy Peanut Butter (1 cup): The star of the show! Jif Creamy Peanut Butter offers a classic flavor and smooth consistency.
Large Eggs (2): Act as a binder and add richness.
Pure Vanilla Extract (1 teaspoon): Enhances the overall flavor. McCormick Pure Vanilla Extract is a staple in my kitchen.
All-Purpose Flour (1 ¾ cups): The base of our cookie dough. King Arthur Baking Company All-Purpose Flour is known for its reliability.
Baking Soda (1 teaspoon): Helps the cookies rise and achieve a slightly chewy texture. Arm & Hammer Pure Baking Soda is a trusted brand.
Ground Cinnamon (½ teaspoon): Adds a warm, comforting spice. McCormick Ground Cinnamon offers a rich flavor.
Salt (½ teaspoon): Balances the sweetness and enhances the other flavors. Morton Kosher Salt is my go-to.
Old-Fashioned Rolled Oats (3 cups): Provide texture and a nutty flavor. Quaker Old Fashioned Oats are a classic choice.


Step-by-Step Instructions for Perfect Peanut Butter Oatmeal Cookies
Follow these detailed instructions to bake a batch of perfect peanut butter oatmeal cookies.
Prep Time: 15 minutes
Bake Time: 10-12 minutes per batch
Total Time: Approximately 30-40 minutes
Step 1: Cream Together the Wet Ingredients (5 minutes)
In a large mixing bowl, cream together the softened unsalted butter, granulated sugar, and packed brown sugar using a handheld mixer or a stand mixer fitted with the paddle attachment. Beat until the mixture is light and fluffy. This usually takes about 2-3 minutes. Scraping down the sides of the bowl occasionally ensures everything is evenly incorporated.
Step 2: Add Peanut Butter and Vanilla (2 minutes)
Add the creamy peanut butter to the bowl and continue to beat until well combined and smooth. Stir in the pure vanilla extract.
Step 3: Incorporate the Eggs (3 minutes)
Beat in one large egg at a time, mixing well after each addition until fully incorporated. Make sure the mixture is smooth before adding the second egg.
Step 4: Combine the Dry Ingredients (2 minutes)
In a separate medium bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt until well combined. This ensures that the leavening agent and spices are evenly distributed throughout the dough.
Step 5: Gradually Add Dry Ingredients to Wet Ingredients (3 minutes)
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can lead to tough cookies. Stop mixing as soon as you no longer see streaks of flour.
Step 6: Stir in the Oats (2 minutes)
Add the old-fashioned rolled oats to the cookie dough and gently fold them in using a spatula until they are evenly distributed throughout.
Step 7: Chill the Dough (Optional but Recommended - 15-30 minutes)
While not strictly necessary, chilling the dough for 15-30 minutes can help prevent the cookies from spreading too much during baking and result in a thicker, chewier cookie. Cover the bowl with plastic wrap and refrigerate.
Step 8: Preheat Oven and Prepare Baking Sheets (2 minutes)
Preheat your oven to 375°F (190°C). Line your Wilton Recipe Right Nonstick Cookie Sheets with Silpat Premium Non-Stick Silicone Baking Mats or parchment paper.
Step 9: Scoop and Arrange Cookie Dough (5 minutes)
Use a Good Grips Medium Cookie Scoop to drop rounded tablespoons of cookie dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie.
Step 10: Bake the Cookies (10-12 minutes)
Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers still look slightly soft. The baking time may vary slightly depending on your oven.
Step 11: Cool on Baking Sheets (5 minutes)
Once the cookies are out of the oven, let them cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. This allows them to set slightly and prevents them from breaking.
Step 12: Enjoy!
Once cooled, your delicious peanut butter oatmeal cookies are ready to be enjoyed!
Expert Tips for Perfect Peanut Butter Oatmeal Cookies
Here are a few expert tips to ensure your peanut butter oatmeal cookies turn out perfect every time:
Use Softened Butter: Make sure your unsalted butter is properly softened to room temperature. This allows it to cream smoothly with the sugar, creating a light and airy base for your cookies. If you forget to take it out in advance, you can gently warm it in short intervals in the microwave, but be careful not to melt it.
Don't Overmix the Dough: Overmixing the dough, especially after adding the flour, can develop the gluten and result in tough cookies. Mix until the dry ingredients are just combined, then gently fold in the oats.
Chill the Dough (If You Have Time): As mentioned earlier, chilling the dough helps to prevent excessive spreading and can enhance the flavor. Even a short 15-minute chill can make a difference.
Use a Cookie Scoop for Uniformity: Using a cookie scoop ensures that all your cookies are the same size, which leads to even baking. It also makes the process quicker and less messy.


Variations to Try for Your Next Batch
Want to mix things up? Here are a few creative variations you can try with this peanut butter oatmeal cookie recipe:
Peanut Butter Chocolate Chip Oatmeal Cookies: Add 1 cup of your favorite chocolate chips (milk, semi-sweet, or dark) to the dough along with the oats for an extra layer of deliciousness.
Peanut Butter Oatmeal Raisin Cookies: Stir in ½ cup of raisins or other dried fruit like cranberries for added chewiness and sweetness. You can also soak the raisins in warm water for a few minutes to plump them up before adding them to the dough.
Double Peanut Butter Cookies: For an even more intense peanut butter flavor, use chunky peanut butter instead of creamy, or add a tablespoon of peanut butter powder to the dry ingredients.
Why These Peanut Butter Oatmeal Cookies Stand Out
These peanut butter oatmeal cookies aren't just another cookie recipe. They strike the perfect balance between the rich, nutty flavor of peanut butter and the wholesome chewiness of oats. The combination of granulated and brown sugar creates a delightful texture that’s both soft and slightly crisp around the edges. The hint of cinnamon adds a warm, comforting note that elevates these cookies beyond the ordinary. This recipe is also incredibly versatile, allowing you to customize it with your favorite additions to create a truly unique treat. Whether you enjoy them with a cold glass of milk or a warm cup of coffee, these cookies are a guaranteed delight.


Storing and Serving Suggestions
To keep your peanut butter oatmeal cookies fresh, store them in an airtight container at room temperature for up to 3-4 days. For longer storage, you can freeze the baked cookies for up to 3 months. Simply thaw them at room temperature before serving.
These cookies are perfect for:
An afternoon snack
A sweet treat with your morning coffee
Packing in lunch boxes
Serving at parties and gatherings
Gifting to friends and family
Warm them slightly in the microwave for an extra gooey experience!
Final Thoughts on These Delightful Cookies
These peanut butter oatmeal cookies are a testament to the fact that sometimes the simplest recipes are the most satisfying.
