Chocolate Chip Peanut Butter Oatmeal Cookies Recipe: Step-by-Step Guide

Now, let’s get to the fun part—baking these scrumptious cookies! Follow these steps to whip up a batch of Chocolate Chip Peanut Butter Oatmeal Cookies.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure it’s hot and ready for baking.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, add 1 cup (226g) of softened butter, 1 cup (213g) of packed brown sugar, and 1 cup (198g) of granulated sugar. Using an electric mixer, cream the mixture together until it’s light and fluffy, approximately 2-3 minutes.
Step 3: Add Eggs and Vanilla
Crack in 2 large eggs (100g) and add 1 tablespoon (14g) of vanilla extract. Mix until fully incorporated, scraping down the sides of the bowl as needed.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together 3 cups (360g) of all-purpose flour, 1 teaspoon (4g) of sea salt, and ½ teaspoon (4g) of baking soda. Gradually add this dry mixture to the wet ingredients, mixing just until combined.
Step 5: Stir in Oats and Chips
Gently fold in 1 ½ cups (45g) of quick-cooking oats, 1 cup (170g) of chocolate chips, and 1 cup (168g) of peanut butter chips to the dough.
Step 6: Scoop the Dough
Using a cookie scoop or a tablespoon, drop rounded balls of dough onto lined baking sheets, spacing them about 2 inches apart.
Step 7: Bake
Place the baking sheets in the preheated oven and bake for 10-12 minutes, or until the edges are golden brown and the centers are set but still soft.
Step 8: Cool and Enjoy
Remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes before transferring them to wire racks to cool completely. Enjoy your homemade Chocolate Chip Peanut Butter Oatmeal Cookies with a glass of milk or a warm cup of coffee!
In-Season Swaps

Feel free to customize your cookies based on seasonal ingredients or personal preferences:
- Nut Butters: Swap peanut butter chips with almond butter chips for a different nutty flavor.
- Dried Fruits: Add in some dried cranberries or raisins for a fruity twist.
- Spices: A sprinkle of cinnamon or nutmeg can add warmth and depth during fall and winter.
- Chocolate Variations: Use white chocolate chips or dark chocolate chips for a different flavor profile.
Avoid These Mistakes
To ensure your cookies turn out perfectly, keep these common mistakes in mind:
- Don’t overmix the dough once you add the flour; this can lead to tough cookies.
- Measure your flour correctly; using too much can make your cookies dry.
- Allow the cookies to cool on the baking sheet before transferring them; this helps them set properly.
- Use room temperature ingredients; cold butter or eggs can affect the texture of your cookies.
Leftovers & Meal Prep
These cookies store beautifully, making them perfect for meal prep:
Store any leftovers in an airtight container at room temperature for up to one week. You can also freeze the cookie dough for future baking. Simply scoop the dough onto a baking sheet, freeze until solid, then transfer the dough balls to a freezer bag. When you’re ready for fresh cookies, just bake from frozen, adding a couple of extra minutes to the baking time!
Reader Questions
Can I substitute other types of flour for all-purpose flour?
Yes, you can use whole wheat flour or a gluten-free flour blend, but keep in mind that the texture and flavor might vary slightly.
What if I don’t have quick-cooking oats?
Old-fashioned oats can be used, but they may create a chewier texture. Just make sure to chop them a bit to mimic the quick-cooking kind.
How can I make these cookies healthier?
You can reduce the sugar by a third, use natural sweeteners like honey or maple syrup, and add in seeds like chia or flax for added nutrition.
Can I use only chocolate chips instead of peanut butter chips?
Absolutely! Feel free to double the amount of chocolate chips if you prefer a richer chocolate flavor.
