Why This Chocolate Chip Peanut Butter Oatmeal Skillet Cookie Stands Out

This recipe stands out for several reasons. First, the combination of creamy peanut butter and rich chocolate chips creates a flavor explosion that is simply irresistible. The addition of oats not only enhances the texture but also adds a wholesome element that makes you feel a little less guilty about indulging. Furthermore, the use of a skillet means you can bake and serve in the same dish, making cleanup a breeze. Whether you’re hosting a cozy gathering or just treating yourself, this skillet cookie is sure to impress!

- 1 large egg: Binds the ingredients together for a perfect cookie dough.
- 2 teaspoons vanilla extract: Enhances the flavor and aroma of your cookie.
- 1 cup all-purpose flour: The backbone of the cookie structure.
- 1 teaspoon baking soda: Helps the cookie rise and gives it a fluffy texture.
- 1 teaspoon salt, optional and to taste: Balances the sweetness and enhances flavors.
- 1 ½ cups old-fashioned whole rolled oats, not quick cook or instant: Provides chewiness and a wholesome element.
- 1 (14-ounce) can sweetened condensed milk: Adds creaminess and sweetness, making the cookie soft and gooey.
- 1 cup creamy peanut butter: The star ingredient that brings a nutty flavor and richness.
- 1 cup semi-sweet chocolate chips: For that chocolatey goodness that everyone loves.
- Ice cream, optional: A delightful addition for serving, enhancing the warmth of the cookie.
Appliances & Accessories
- Skillet: A cast iron skillet works best for even baking and heat retention.

Cooking Chocolate Chip Peanut Butter Oatmeal Skillet Cookie: The Process

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your skillet cookie will bake evenly and perfectly.
Step 2: Prepare Your Skillet
Grease your skillet with a little butter or cooking spray to prevent sticking. Set it aside while you prepare the dough.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, combine the melted butter and light brown sugar. Whisk together until smooth. Then, add in the large egg and vanilla extract, mixing well until fully incorporated.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring gently until just combined.
Step 5: Fold in the Oats and Peanut Butter
Carefully fold in the old-fashioned oats and creamy peanut butter until evenly distributed throughout the dough.
Step 6: Add Chocolate Chips
Gently fold in the semi-sweet chocolate chips, ensuring they are spread evenly throughout the dough.
Step 7: Bake the Cookie
Pour the cookie dough into the prepared skillet, spreading it out evenly. Bake in the preheated oven for 25-30 minutes or until the edges are golden brown and the center is set but still slightly soft.
Step 8: Cool and Serve
Once baked, remove the skillet from the oven and let it cool for a few minutes. Serve warm, optionally topped with a scoop of your favorite ice cream for an extra indulgent treat!
Allergy-Friendly Substitutes

- Dairy-Free Alternative: Substitute the unsalted butter with coconut oil or a dairy-free butter alternative.
- Gluten-Free Option: Use a 1:1 gluten-free all-purpose flour blend in place of regular flour.
- Nut-Free Choice: Replace peanut butter with sunflower seed butter or a similar nut-free spread.
- Lower Sugar Version: Use a sugar substitute designed for baking, keeping in mind the sweetness level may vary.
Recipe Notes & Chef’s Commentary
For the best flavor and texture, make sure to use old-fashioned rolled oats as they provide a heartiness that quick oats lack. If you prefer extra chocolatey goodness, feel free to add more chocolate chips! This cookie can be enjoyed warm right out of the oven or stored for a couple of days in an airtight container. Just a quick reheating in the microwave will bring back that warm, gooey texture.
Best Ways to Store
Store any leftover Chocolate Chip Peanut Butter Oatmeal Skillet Cookie in an airtight container at room temperature for up to 3 days. For longer storage, cover the skillet with plastic wrap or foil and refrigerate for up to a week. To reheat, simply pop it in the microwave for a few seconds until warm.
