Step-by-step Preparation of Big Fat Peanut Butter Oatmeal Chocolate Chip Cookies
To make big fat peanut butter oatmeal chocolate chip cookies that are not just delicious but also incredibly easy to prepare, follow this step-by-step guide. Let’s get those ingredients ready and dive in!
Gather your supplies and preheat your oven
First and foremost, let’s ensure you have everything you need for this cookie baking adventure. Gather the following supplies:
- Medium and large mixing bowls
- Measuring cups and spoons
- A hand mixer or stand mixer
- Baking sheets lined with parchment paper or silicone mats
- A medium cookie scoop
Once you’ve set up your workspace, it’s time to preheat your oven to 350°F (177°C). This is an essential step to ensure that your cookies bake evenly and turn out perfectly chewy!
Mix dry ingredients in a bowl
In a medium bowl, whisk together:
- 1 and ½ cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
Mixing these dry ingredients first allows the leavening agents to distribute evenly throughout the flour, ensuring your cookies rise beautifully. Set this bowl aside for later!
Cream the butter and sugars
Now for the creamy goodness! In a large bowl, use your mixer to beat together:
- 1 cup softened unsalted butter
- 1 cup granulated sugar
- ½ cup packed brown sugar
Beat these ingredients on medium-high speed until well-combined and fluffy—this should take about 2 minutes. The creaminess lays the foundation for your big fat peanut butter oatmeal chocolate chip cookies.
Combine the wet ingredients
Next up, let’s add some flavor and richness. To the butter and sugar mixture, add:
- 2 large eggs
- 1 cup creamy peanut butter
- 2 teaspoons pure vanilla extract
Mix everything on high-speed until thoroughly combined. This is the point where your kitchen will start to smell like pure bliss!
Combine wet and dry ingredients along with oats and chocolate chips
Now it’s time to bring it all together. Gradually add the dry mixture to the wet ingredients, mixing on low speed to avoid a flour explosion. Once combined, fold in:
- 2 cups old-fashioned rolled oats
- 2 and ½ cups semi-sweet chocolate chips
The dough will be thick and sticky, which is perfect for these substantial cookies.
Chill the dough for the best texture
While it’s tempting to bake right away, chilling the dough for at least 20 minutes in the refrigerator will yield a better texture and flavor. If you can wait, aim for longer—up to 4 days! This creates a richer taste.
Shape and bake the cookies
Using a medium cookie scoop, portion out 2 tablespoons of dough per cookie and place them 3 inches apart on your lined baking sheets. Bake for 12-14 minutes or until the edges are lightly browned. The centers may seem soft, which is just what you want for that gooey goodness.
Remove from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. For that extra touch, consider pressing a few more chocolate chips onto the tops while they are still warm!
And there you have it! You’re now ready to enjoy big fat peanut butter oatmeal chocolate chip cookies that promise to be a surefire hit with friends and family.

Variations of Big Fat Peanut Butter Oatmeal Chocolate Chip Cookies
Gluten-free options
If you’re looking for a gluten-free twist on these delightful big fat peanut butter oatmeal chocolate chip cookies, substitute all-purpose flour with a 1:1 gluten-free blend, such as Bob's Red Mill or King Arthur. These blends typically include xanthan gum, which helps provide structure and moisture to the cookies. Just keep in mind, your baking time may vary slightly, so keep an eye on those cookies as they bake!
Vegan adaptations
Want to make these cookies egg-free? You can easily convert the big fat peanut butter oatmeal chocolate chip cookies into a vegan treat! Use a flax egg (mix one tablespoon of ground flaxseed with three tablespoons of water and let it sit until it thickens) to replace each egg. Instead of butter, opt for coconut oil or a vegan butter substitute. With these simple swaps, you’ll have a delicious batch of cookies that everyone can enjoy, regardless of their dietary restrictions! For more vegan baking tips, check out Minimalist Baker.
Cooking Tips and Notes for Big Fat Peanut Butter Oatmeal Chocolate Chip Cookies
Finding the Best Peanut Butter for Cookies
When it comes to big fat peanut butter oatmeal chocolate chip cookies, the peanut butter you choose can make or break your batch! It's best to opt for a creamy, no-stir peanut butter like Jif or Skippy. These brands provide the perfect consistency, ensuring your cookies are rich and chewy. Avoid natural peanut butter, as it tends to make the cookies crumbly. Want crunch? Feel free to experiment with crunchy peanut butter for a little extra texture!
How to Store Cookies for Maximum Freshness
To maintain that fresh-baked taste, store your cookies in an airtight container at room temperature. They’ll stay delicious for about a week, but I bet they won’t last that long! If you want to save some for later, consider freezing them. Baked cookies can freeze well for up to three months. Just pop them in a zip-top bag, and you’ll have a sweet treat ready whenever cravings hit! For more on cookie storage, check out this handy guide on food storage tips.

- Cooling Rack
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 old-fashioned whole rolled oats
- 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.
