Step-by-step Preparation of Big Fat Peanut Butter Oatmeal Chocolate Chip Cookies
Making the big fat peanut butter oatmeal chocolate chip cookies is not only an exciting culinary adventure but also an opportunity to create something delicious that you can share—or simply enjoy on your own. Let’s get started!
Gather and Measure Your Ingredients
First things first, gather all your ingredients. This includes:
- 1 and ½ cups all-purpose flour
- 1 cup unsalted butter, softened
- 1 cup granulated sugar
- ½ cup packed brown sugar
- 2 eggs
- 1 cup creamy peanut butter
- 2 teaspoons vanilla extract
- 2 cups rolled oats
- 2 and ½ cups semi-sweet chocolate chips
Accurate measurements are key for baking success, so take your time here! If you're unsure how to measure flour properly, this guide on how to measure baking ingredients is super helpful.
Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This step ensures that your leavening agents are evenly distributed, helping your cookies rise nicely.
Cream the Butter and Sugars
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar using a hand mixer or stand mixer. Beat until it’s light and fluffy, about 2 minutes. Don’t forget to scrape down the sides of the bowl for even mixing!
Incorporate Wet Ingredients
Next, add the eggs, peanut butter, and vanilla extract. Continue to beat on high until everything is fully combined—this usually takes about a minute. Just think, soon you’ll be savoring those big fat peanut butter oatmeal chocolate chip cookies!
Combine Dry and Wet Ingredients
With the mixer on low speed, gradually mix in your flour mixture. As the dough begins to form, add in your oats and then the chocolate chips. The dough will be thick and a bit sticky, which is just perfect!
Chill the Dough for Optimal Texture
Cover your cookie dough and chill it in the refrigerator for at least 20 minutes, or up to 4 days. Chilling firms up the dough, which helps prevent spreading—resulting in beautifully thick cookies.
Preheat Oven and Prepare Baking Sheets
While your dough chills, preheat your oven to 350°F (177°C). Line your baking sheets with parchment paper or a silicone baking mat to ensure easy cleanup and prevent sticking.
Scoop and Space Out the Cookies
Once the dough is chilled, scoop out about 2 tablespoons of dough for each cookie. Place them at least three inches apart on your prepared baking sheets. This is crucial as they will spread while baking!
Bake to Perfection
Pop those cookies in your preheated oven. Bake for about 12-14 minutes until the edges are lightly browned but the centers remain soft. It’s hard, but try to resist the urge to open the oven door too soon!
Cool and Enjoy!
After baking, let your cookies sit on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. This waiting period helps them firm up beautifully. If you like, you can press a few extra chocolate chips into the tops of the warm cookies for that extra touch!
Now that you have your big fat peanut butter oatmeal chocolate chip cookies, all there’s left to do is enjoy them! Whether you share with friends or savor them with a glass of your favorite milk, these cookies are bound to be a hit!

Cooking Tips and Notes for Big Fat Peanut Butter Oatmeal Chocolate Chip Cookies
Importance of Chilling the Dough
Chilling the dough for big fat peanut butter oatmeal chocolate chip cookies is crucial for achieving the right texture. When you let the dough rest in the fridge for at least 20 minutes (or up to 4 days!), you allow the flavors to meld and the butter to firm up. This prevents spreading, resulting in thick, chewy cookies. If your dough has chilled for more than an hour, let it sit at room temperature for about 30 minutes before baking to soften it slightly, making scooping and shaping easier.
Tips for a Perfect Texture
To get that ideal chewy and thick cookie, consider these tips:
- Use a proper measuring technique for your flour—spooned and leveled is key.
- Opt for creamy, non-natural peanut butter, as it provides the best consistency.
- Don’t overmix the dough; mix just until combined to avoid tough cookies.
