Ingredient List

- 1/2 cup creamy peanut butter
- 1/2 teaspoon vanilla extract (I used Beanilla Vanilla Paste for added depth)

- 1 cup all-purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup rolled oats
- 1 cup peanut butter and chocolate swirl chips (or your favorite chocolate chips)
Appliances & Accessories
- Mixing bowl: A large bowl for combining ingredients.
- Electric mixer: For creaming butter and sugars effortlessly.
- Baking sheet: To bake the cookies; line with parchment for easy cleanup.
- Cookie scoop: Helps in portioning out cookies evenly.
- Cooling rack: For cooling cookies once they come out of the oven.
Oatmeal-Peanut Butter Chip Cookies Made Stepwise

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure it’s hot and ready for baking. This step is crucial for achieving that perfect cookie texture.
Step 2: Cream Butter and Sugars
In a large mixing bowl, combine the softened butter, white sugar, and brown sugar. Using an electric mixer, cream them together until the mixture is light and fluffy. This should take about 2-3 minutes.
Step 3: Add Peanut Butter and Vanilla
Add the creamy peanut butter and vanilla extract to the creamed mixture. Mix until thoroughly combined, scraping down the sides of the bowl as needed.
Step 4: Incorporate the Egg
Add the egg into the mixture and beat until it is fully incorporated. This will help bind the ingredients together.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Once well mixed, gradually add this dry mixture to the wet ingredients, stirring gently until just combined.
Step 6: Fold in Oats and Chips
Gently fold in the rolled oats and peanut butter and chocolate swirl chips until evenly distributed throughout the dough.
Step 7: Scoop and Bake
Using a cookie scoop or spoon, drop rounded tablespoons of dough onto a baking sheet lined with parchment paper. Leave enough space between each cookie for spreading. Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
Step 8: Cool and Enjoy
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a cooling rack. This allows them to set perfectly. Enjoy your Oatmeal-Peanut Butter Chip Cookies warm or store them for later!
No-Store Runs Needed

- Butter: Always keep a stash of butter in your fridge or freezer.
- Peanut Butter: A pantry staple that lasts a long time.

- Oats: Rolled oats are versatile and can be used in many recipes.

Little Things that Matter
When making Oatmeal-Peanut Butter Chip Cookies, remember that the quality of your ingredients can make a significant difference. Using fresh peanut butter and high-quality chocolate chips will elevate the flavor. Additionally, letting your butter soften at room temperature ensures it creams nicely with the sugars, resulting in a better texture.
- Try adding a pinch of cinnamon for a warm, comforting flavor.
- For an extra crunch, consider adding chopped nuts like walnuts or pecans.
- If you prefer a more robust peanut butter flavor, use crunchy peanut butter instead of creamy.
Refrigerate, Freeze, Reheat
These cookies are great for meal prep or to have on hand for unexpected guests. Here’s how to store them:
- Refrigerate: Store in an airtight container in the fridge for up to a week.
- Freeze: Freeze cookie dough balls on a baking sheet, then transfer to a freezer bag. They can be stored for up to 3 months!
- Reheat: Warm cookies in the microwave for about 10-15 seconds for that freshly-baked taste.
Ask the Chef
Can I substitute the peanut butter with another nut butter?
Absolutely! Almond butter, cashew butter, or sunflower seed butter can be used as alternatives. Just keep in mind that the flavor and texture may vary slightly.
How can I make these cookies gluten-free?
To make these cookies gluten-free, simply substitute the all-purpose flour with a 1:1 gluten-free baking blend. Ensure that all other ingredients are also gluten-free.
Can I add other mix-ins?
Definitely! Feel free to add in chopped dried fruits, nuts, or even a sprinkle of sea salt on top before baking for an extra flavor boost.
What if the dough is too sticky?
If your dough feels too sticky, chill it in the refrigerator for about 30 minutes. This will make it easier to scoop and handle.
