Step-by-Step Preparation of Big Fat Peanut Butter Oatmeal Cookies
Baking a batch of big fat peanut butter oatmeal cookies is a delightful adventure, and with the right guidance, it can be a fun and satisfying experience! Let’s walk through the preparation step by step.
Gather Your Tools and Ingredients
Before diving into the mixing bowl, it’s essential to gather all your tools and ingredients. Here's what you'll need:
-
Ingredients:
-
All-purpose flour, baking powder, baking soda, salt
-
Unsalted butter, granulated sugar, brown sugar
-
Eggs, creamy peanut butter, pure vanilla extract
-
Old-fashioned rolled oats, semi-sweet chocolate chips
-
Tools:
-
Mixing bowls
-
Electric mixer (handheld or stand)
-
Baking sheets
-
Parchment paper or silicone mats
-
Measuring cups and spoons
Having everything on hand not only streamlines your process but also helps to avoid those last-minute trips to the store!
Mix the Dry Ingredients Together
Begin by whisking together:
- 1 and ½ cups of all-purpose flour
- 1 teaspoon of baking powder
- 1 teaspoon of baking soda
- 1 teaspoon of salt
Once evenly combined, set this bowl aside. This simple step ensures that your leavening agents are distributed evenly throughout the cookies, providing that perfect rise.
Cream the Butter and Sugars
In a large bowl, beat 1 cup of softened butter on medium-high speed until smooth (about 1 minute). Add 1 cup of granulated sugar and ½ cup of brown sugar, and cream them together for about 2 minutes. This process incorporates air into the mix, giving your cookies that lovely, chewy texture.
Combine Wet Ingredients
Add 2 large eggs (at room temperature), 1 cup of creamy peanut butter, and 2 teaspoons of pure vanilla extract to the bowl. Beat on high until everything is well combined. This will be the flavorful base of your big fat peanut butter oatmeal cookies.
Incorporate Dry Ingredients and Oats
Gradually add the dry mixture to the wet mixture, mixing on low until just combined. Then, introduce 2 cups of old-fashioned rolled oats and mix until everything is thick and sticky. You can almost taste the deliciousness at this stage!
Chill the Dough for Optimal Texture
To enhance the flavors and give your cookies a better texture, cover the dough and chill it in the refrigerator for at least 20 minutes. Chilling allows the ingredients to meld together beautifully.
Preheat the Oven and Prepare Baking Sheets
While the dough is chilling, preheat your oven to 350°F (177°C). Line your baking sheets with parchment paper or silicone mats, setting yourself up for easy cleanup later.
Shape and Place Dough on Sheets
Scoop balls of dough (about 2 tablespoons each) and arrange them on the prepared baking sheets, spaced about 3 inches apart. This allows the cookies to spread without merging into one big cookie!
Bake and Cool Your Cookies
Bake for about 12-14 minutes, until the edges are lightly browned while the centers remain soft. Let the cookies cool on the baking sheet for about 5 minutes, then transfer them to a wire rack to cool completely. If you have extra chocolate chips, press a few into the tops while they’re warm for that photogenic touch!
Now, you’re all set to enjoy your big fat peanut butter oatmeal cookies! They’ll stay fresh for up to a week, but let’s be honest, they probably won’t last that long. Happy baking!

Variations on Big Fat Peanut Butter Oatmeal Cookies
Vegan Options for Peanut Butter Oatmeal Cookies
If you're looking to enjoy big fat peanut butter oatmeal cookies without the eggs and dairy, you’re in luck! Replace the eggs with flaxseed meal or chia seeds. Simply mix 1 tablespoon of either with 2.5 tablespoons of water, let it sit for a few minutes, and voilà! For a dairy-free alternative, substitute regular butter with coconut oil or your favorite vegan butter. You can also use maple syrup or coconut sugar instead of granulated sugar for a touch of natural sweetness. Discover more about these ingredients here!
Gluten-Free Alternative Suggestions
Craving big fat peanut butter oatmeal cookies but need to go gluten-free? No problem! You can swap out all-purpose flour with gluten-free flour blends. Just make sure they contain xanthan gum for the best texture. Oats can be tricky, so opt for certified gluten-free rolled oats to keep everything safe.

To achieve the ultimate big fat peanut butter oatmeal cookies, aim for precision in your measurements, especially with ingredients like flour.

Big Fat Peanut Butter Oatmeal Chocolate Chip Cookies
Equipment
- mixing bowl
- hand mixer
- Stand Mixer
- baking sheets
- parchment paper
- Cooling Rack
- cookie scoop
Ingredients
- 1.5 cups all-purpose flour spooned & leveled
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 cup unsalted butter softened to room temperature
- 1 cup granulated sugar
- 0.5 cup brown sugar packed light or dark
- 2 large eggs at room temperature
- 1 cup creamy peanut butter
- 2 teaspoons pure vanilla extract
- 2 cups whole rolled oats old-fashioned
- 2.5 cups semi-sweet chocolate chips plus more for topping if desired
Instructions
- Whisk the flour, baking powder, baking soda, and salt together in a medium bowl. Set aside.
- In a large bowl using a hand mixer or a stand mixer fitted with a paddle attachment, beat the butter on medium-high speed until smooth, about 1 minute. Add the granulated sugar and brown sugar and beat on medium-high speed until creamed, about 2 minutes. Add the eggs, peanut butter, and vanilla and beat on high speed until combined, about 1 minute. Scrape down the sides and up the bottom of the bowl and beat again as needed to combine.
- Add the dry ingredients to the wet ingredients and mix on low until combined. With the mixer running on low speed, add the oats. Once combined, beat in the chocolate chips. Dough will be thick and sticky. Cover and chill the dough for at least 20 minutes in the refrigerator (and up to 4 days). If chilling for longer than 1 hour, allow to sit at room temperature for at least 30 minutes before rolling and baking because the dough will be quite hard.
- Preheat oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats. Set aside.
- Scoop balls of dough, 2 Tablespoons of dough per cookie, and arrange 3 inches apart on the baking sheets. Bake for 12-14 minutes until lightly browned on the sides. The centers will look very soft.
- Remove from the oven and allow to cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely. While the cookies are still warm, I like to press a few more chocolate chips into the tops—this is only for looks!
- Cookies stay fresh covered at room temperature for up to 1 week.
