This Brown Butter Oatmeal Cookie Skillet is chewy, gooey, buttery, and basically the dessert equivalent of your favorite pair of cozy socks. It’s warm, nostalgic, and best served straight from the pan with a big scoop of vanilla ice cream.
You get all the best parts of a cookie, crispy golden edges, a soft gooey center, pools of melty chocolate, but without the effort of scooping individual dough balls. Plus, it’s made with nutty brown butter and hearty oats, which basically makes it a classy, grown-up cookie skillet... that still makes you feel like a kid.

- Made in one skillet: No scooping, no chilling, no stress.

- Melty chocolate + warm oats = heaven

Brown Butter Oatmeal Cookie Skillet Ingredients
Here’s the rundown:
- Salted butter: We’re browning this for rich, toasty, nutty flavor. It’s the secret to making this skillet taste 100x more special.
- Brown sugar + granulated sugar: A combo for depth and sweetness. Brown sugar brings the chew, white sugar brings the crisp edges.
- Egg + egg yolk: The extra yolk gives us that thick, rich, fudgy center.
- Vanilla extract: Always. We’re going for warm, buttery bakery vibes here.
- All-purpose flour: Just enough to hold everything together while keeping it soft.
- Rolled oats: Adds chew and texture, makes the cookie feel a little heartier and rustic (in a good way).
- Cinnamon: A subtle hint of spice to warm it up.
- Baking soda + baking powder: A little of each gives us that soft lift and perfect spread.
- Salt: Enhances everything and balances the sweetness.
- Chocolate chips or chopped chocolate: Use whatever you’ve got, but chopped dark chocolate = puddles.
- Flaky sea salt: Optional but very recommended for that salty-sweet finish.
Tips, Tricks, and Substitutions
- Chill the dough (optional): Not necessary, but if you’ve got the time, a 30-minute chill gives even richer flavor and thicker texture.
- Don’t overbake it: Pull it from the oven when the center is still a little soft—it will firm up as it cools.
- Add nuts: Chopped walnuts or pecans would be amazing.
- Skip the skillet? Use a 9-inch cake pan or pie dish. Still delish!
FAQs
Can I make this ahead of time?
Yes! You can brown the butter and mix the dough in advance. Press it into the skillet, cover, and chill for up to 24 hours before baking.
What kind of oats should I use?
Old-fashioned rolled oats are best! Quick oats will make it too soft, and steel-cut won’t cook properly.
What kind of chocolate should I use?
I love using semi-sweet or dark chocolate because they balance out the sweetness of the cookie really well. But honestly, use what you love.
Can I make this ahead of time?
Yep! You can bake the whole skillet cookie ahead of time, then just pop it back in the oven for a few minutes to warm it up before serving. Wait to add the ice cream and caramel until right before you serve it so everything stays melty and perfect.
Do I have to serve it with ice cream and caramel?
You don’t have to... but it’s kind of the whole vibe. The combo of warm cookie, cold ice cream, and gooey caramel is what makes this dessert next-level.
Can I make this gluten-free?
Totally! Just use a 1:1 gluten-free flour blend and certified GF rolled oats.
Do I need to use flaky salt on top?
Technically no, but flavor-wise? YES. It makes the chocolate pop and balances the sweetness perfectly.
How can I tell when it’s ready to come out of the oven?
Keep an eye on the edges; they should be golden brown and slightly crisp. The center should look set but still a little soft and gooey (that’s where the magic is!). Start checking around 28 minutes at 350°F. It’s better to slightly underbake than overdo it. Remember, it’ll keep cooking a bit as it cools in the skillet.
How to Store Brown Butter Oatmeal Cookie Skillet
If you somehow don’t finish the whole thing in one sitting (impressive), here’s how to keep it fresh:
- Room temperature: Let the cookie skillet cool completely, then cover it tightly with foil or plastic wrap. It’ll stay soft and delicious for up to 2 days on the counter.
- Fridge: For longer storage, pop it in the fridge for up to 5 days. Warm slices in the microwave for 10–15 seconds to bring back the gooey magic.
- Freezer: You can freeze leftover slices too. Just wrap them individually in plastic wrap, place in a freezer bag, and freeze for up to 2 months. Reheat in the microwave or oven until warm.

Brown Butter Oatmeal Cookie Skillet
Ingredients
- 1 cup salted butter, browned
- 3/4 cup light brown sugar, packed
- 1/3 cup granulated sugar
- 1 large egg
- 1 egg yolk
- 1 1/2 tsp vanilla extract
- 1 1/4 cup all purpose flour
- 1 1/2 cup rolled oats
- 1 tsp ground cinnamon
- 1/2 tsp baking soda
- 1/2 tsp baking powder
- 1/2 tsp kosher salt
- 1 1/2 cup chocolate chips
- flaky sea salt (optional)
Instructions
- Brown the butter:In a medium saucepan, melt the butter over medium heat, swirling occasionally. Continue cooking until it foams, crackles, and smells nutty. Golden brown bits will form at the bottom (about 5–7 minutes). Immediately pour into a large mixing bowl and let cool for 10–15 minutes.
- Preheat the oven to 350°F. Grease a 10-inch cast iron skillet or oven-safe skillet.
- Make the dough:Once the brown butter has cooled slightly, whisk in the brown sugar and granulated sugar until smooth. Add the egg, egg yolk, and vanilla, and whisk until creamy and glossy.
- Add dry ingredients:In a separate bowl, mix flour, oats, cinnamon, baking soda, baking powder, and salt. Add to the wet ingredients and stir until just combined.
- Fold in chocolate chips. Reserve a small handful for the top.
- Press the dough into the skillet, spreading evenly. Top with remaining chocolate chips and a sprinkle of flaky salt.
- Bake for 18–22 minutes, until the edges are golden and set but the center is still soft.
- Serve warm, straight from the skillet with big scoops of vanilla ice cream. You will want seconds.
