What Goes Into Chocolate Chip Peanut Butter Oatmeal Skillet Cookie

When it comes to the ingredients for the Chocolate Chip Peanut Butter Oatmeal Skillet Cookie, each one plays a pivotal role in creating the perfect blend of flavors and textures. The combination of butter, brown sugar, and peanut butter provides a rich base, while the oats add heartiness, making this cookie not just a treat, but a delightful experience.
- 10 tablespoons butter (softened): This is the foundation of our cookie, providing richness and flavor.
- 1 cup firmly packed light brown sugar: Adds sweetness and a wonderful caramel flavor.
- 1 large egg + 1 egg yolk: The egg helps bind everything together while the yolk adds moisture.
- 1 teaspoon vanilla extract: Although we avoid artificial vanilla, the real stuff adds a lovely aroma.
- 3/4 cup all-purpose flour: This gives structure to our cookie, ensuring it holds its shape.
- 1 teaspoon baking soda: A leavening agent that helps the cookie rise perfectly.
- 1/4 teaspoon salt: Enhances the flavors and balances the sweetness.
- 1 cup old-fashioned oats (divided): Adds chewy texture and heartiness.
- 2/3 cup semi-sweet chocolate chips (divided): For that sweet, melty goodness that complements peanut butter.

How to Make Chocolate Chip Peanut Butter Oatmeal Skillet Cookie

Making the Chocolate Chip Peanut Butter Oatmeal Skillet Cookie is a delightful process that fills your kitchen with tempting aromas. Let’s dive into the steps to create this indulgent treat, starting with preheating your oven.
Preheat your oven to 325 degrees Fahrenheit. This is crucial for achieving that perfect bake. While the oven heats up, grab your 9-inch cast iron skillet and give it a quick spray with cooking spray to prevent sticking.
Using an electric mixer, beat butter and brown sugar together until the mixture is fluffy and light. This step is important, as it incorporates air into the batter, making your cookie softer.
Add in the egg and egg yolk, along with the vanilla extract. Beat until well combined. This mixture should be smooth and creamy, with a lovely aroma from the vanilla.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this dry mixture to the mixing bowl, beating just until everything is mixed in. Avoid over-mixing to keep your cookie soft.
Now, fold in 3/4 cup of oats and 1/3 cup of chocolate chips using a spatula. You’ll notice the dough becoming thicker and more substantial.
Spread half of the cookie dough evenly in the bottom of your prepared skillet. Use your fingers or a rubber spatula to ensure it’s evenly distributed.
Next, smear the creamy peanut butter over the cookie dough layer. This creates a deliciously gooey center, and you can use as much or as little as you prefer.
Scatter the remaining cookie dough over the top of the peanut butter, ensuring it covers as much surface area as possible. This will create a nice cookie top.
Finally, sprinkle the remaining oats and chocolate chips on top for added texture. It’ll look beautiful and inviting!
Place the skillet in the preheated oven and bake for 45 minutes. Keep an eye on it towards the end; if it starts to brown too much, cover it with aluminum foil. Once baked, let it cool slightly before slicing.
