Preparing Big Fat Peanut Butter Cookies
Baking big fat peanut butter cookies is not just a delightful way to satisfy your sweet tooth; it's a chance to create a warm, nostalgic atmosphere in your kitchen. This recipe merges the creamy richness of peanut butter with wholesome oats and sweet chocolate chips, making these cookies perfect for any occasion. Let’s dive into the step-by-step process to create your masterpiece!
Gather and Measure Your Ingredients
Before you get your hands doughy, it’s essential to gather all your ingredients and measure them accurately. Here’s what you’ll need:
- 1 and ½ cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 cup unsalted butter, softened to room temperature
- 1 cup granulated sugar
- ½ cup packed brown sugar
- 2 large eggs
- 1 cup creamy peanut butter
- 2 teaspoons pure vanilla extract
- 2 cups old-fashioned rolled oats
- 2 and ½ cups semi-sweet chocolate chips
Having everything ready will streamline the process and make baking more enjoyable. Plus, it prevents any last-minute ingredient scrambles!
Mix the Dry Ingredients
Start your cookie journey by whisking together the flour, baking powder, baking soda, and salt in a medium bowl. This step ensures that your big fat peanut butter cookies will have an even rise and texture. By combining the dry ingredients first, you create a well-blended base that will mix beautifully with the wet ingredients later.
Cream the Butter and Sugars
In a large mixing bowl, use a hand mixer or stand mixer fitted with a paddle attachment to beat softened butter until smooth. Then, add the granulated and brown sugars. Beat until the mixture is light and fluffy, about 2 minutes. This aeration process is crucial because it will give your cookies a delicious texture!
Add Eggs, Peanut Butter, and Vanilla Extract
Next, it’s time to mix in the eggs, peanut butter, and pure vanilla extract. Beat everything together until combined. Don't forget to scrape down the sides of the bowl to ensure all ingredients are well incorporated. The goal here is to achieve a velvety mix brimming with rich flavors.
Combine the Wet and Dry Ingredients
Now it’s time to combine everything. Gradually add the dry mixture to the wet ingredients while mixing on low speed. This step prevents any messy explosions of flour. Once they’re mixed, you’ll have a thick and sticky dough—absolutely irresistible!
Incorporate Oats and Chocolate Chips
Fold in the old-fashioned oats and semi-sweet chocolate chips. This is where the magic happens! The oats not only add texture but also provide a wholesome element to your big fat peanut butter cookies. Be generous with the chocolate chips because, let’s face it, who doesn’t love a cookie that’s bursting with chocolate?
Chill the Dough for a Better Texture
Cover your bowl of cookie dough and pop it in the fridge for at least 20 minutes (or up to 4 days). Chilling the dough helps the flavors meld and enhances the cookie's texture, ensuring every bite is chewily perfection. If you chill for more than an hour, let it sit at room temperature for about 30 minutes before rolling for easier handling.
Prepare Baking Sheets and Preheat the Oven
While your cookie dough chills, preheat your oven to 350°F (177°C). Line your baking sheets with parchment paper or silicone baking mats. This will help prevent sticking and make for easier cleanup.
Scoop and Space the Dough on Baking Sheets
Once the dough has chilled, use a medium cookie scoop (about 2 tablespoons worth) to scoop balls of dough onto your prepared baking sheets, spacing them about 3 inches apart. They’ll spread during baking, and you want to give them room to grow!
Bake and Cool the Cookies
Pop the baking sheets into your preheated oven and bake for 12-14 minutes, or until the edges are lightly browned. The centers will still look soft, but don’t worry—they’ll firm up while cooling. After you remove them from the oven, let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. If you want to enhance the presentation, press a few extra chocolate chips into the tops while they’re still warm.
With these comprehensive steps, you're well on your way to baking deliciously big fat peanut butter cookies that will surely impress your friends and family. Enjoy the delightful aroma wafting through your home, and of course, don’t forget to save some for yourself!

Baking Notes for Big Fat Peanut Butter Cookies
Common Mistakes and How to Avoid Them
Creating the perfect big fat peanut butter cookies begins with avoiding a few common pitfalls:
-
Using the Wrong Peanut Butter: Stick with creamy, non-natural peanut butter. Varieties like Jif or Skippy yield the best texture. Natural styles can make them sandy and crumbly.
-
Chilling Time: Don’t skip the chilling process! Allowing the dough to chill for at least 20 minutes ensures thicker cookies that hold their shape during baking. If you're short on time, a quick 30-minute chill can still work wonders.
-
Baking Temperature: Always preheat your oven to 350°F (177°C) for consistent baking. Overbaking can lead to dry cookies, so keep an eye on them—lighter edges and soft centers are ideal!
