Step-by-Step Instructions
- Make the Dry Mix:
- Combine all purpose flour and baking soda in a medium bowl. Stir very well to evenly distribute the baking soda. This ensures every cookie rises the same.
- Cream the Fats:
- In a large mixer bowl beat together creamy peanut butter and unsalted butter until totally smooth and blended. Pause to scrape down the sides so nothing is missed. This base is what guarantees flavor and keeps the cookies irresistibly soft.
- Add Sugar:
- Pour in both brown sugar and granulated sugar. Beat on medium speed until the mixture becomes light and fluffy. The sugars dissolve and whip up the fats so you get a soft chewy crumb.
- Add Eggs and Vanilla:
- Crack in the eggs one at a time mixing fully after each so the dough does not split. Add the vanilla extract and continue mixing until glossy and homogenous.
- Add the Dry to Wet:
- Sprinkle the flour mixture into the wet ingredients. Mix gently until just combined scraping the bowl as needed. Do not overmix or the cookies can toughen.
- Mix in Oats and Chips:
- Add old fashioned oats and peanut butter chips. Stir briefly by hand or mixer just until evenly distributed. Overmixing can break up the oats.
- Chill the Dough:
- Cover the dough bowl tightly and place in the fridge for thirty minutes. This firms up the butter and lets the oats absorb moisture so your cookies bake up thick and hearty.
- Shape and Bake:
- Preheat your oven to three hundred fifty Fahrenheit. Roll the dough into balls using about one and a half tablespoons for each. Place on parchment lined trays leaving three inches between for spreading. For extra flair press a few more peanut butter chips on top of each ball.
- Bake to Perfection:
- Bake the cookies for eleven to thirteen minutes. Look for golden brown edges and matte dry tops as your clue they are done. The centers will finish setting as they cool.
- Cool for Best Texture:
- Let cookies cool on the tray for ten minutes before moving to a rack. This helps them set without crumbling.
Peanut butter chips are my secret weapon because they melt into little pockets of flavor. I still remember the first time my nephew helped me add them in big handfuls and ate half before we started baking.
Storage Tips
Keep extra cookies in an airtight container at room temperature for up to five days. For longer storage freeze in zip bags or tight containers for up to three months. To enjoy later simply thaw at room temperature and they are as fresh as day one.
Ingredient Substitutions
Crunchy peanut butter gives you a nuttier and more textured cookie. Swap in dark or milk chocolate chips for less peanut butter flavor or add chopped peanuts for even more crunch. If you need dairy free use a vegan butter and double check your chips are also dairy free.
Serving Suggestions
They are perfect as lunchbox treats or after school snacks. Pair with a glass of cold milk or hot tea. For special occasions sandwich peanut butter or chocolate frosting between two cookies or crumble over ice cream.
Cultural Note
Peanut butter cookies have been an American classic since the early twentieth century thanks to food innovators who popularized peanut butter as a star ingredient. Adding oats came along later for chewy hearty goodness and makes these cookies feel just like a homemade hug.
