This Old-Fashioned Brownie Skillet Brownie is my go-to when I want a fudgy brownie with those crisp, chewy edges you only really get from a cast iron pan.
It bakes up rich and chocolatey, with a soft center that stays a little gooey in the best way. I like this version because it’s reliable and straightforward, and it tastes like a classic brownie should.
I usually serve it warm as a simple skillet dessert, especially on weekends or when I’m feeding a small group. A scoop of vanilla ice cream on top is never a bad idea.
Why You’ll Love This Recipe
Crisp edges: The cast iron skillet gives you those browned, chewy edges that pan brownies don’t always manage.
Fudgy center: The middle stays soft and thick, especially if you pull it when the center is just barely set.
One bowl feel: It’s a simple batter with no fussy steps, and it comes together fast.
Easy to serve: Slice and serve right from the skillet, or put the whole pan on the table and let everyone help themselves.
Flexible add-ins: Chocolate chips, walnuts, pecans, chopped dark chocolate—use what you like and skip what you don’t.
Ingredients You’ll Need
Dry Ingredients
- All-purpose flour: I use regular flour here. It gives the brownie some structure so the center stays fudgy instead of runny.
- Unsweetened cocoa powder: Use a cocoa you actually like the taste of, because it’s the main flavor. Natural or Dutch-process both work fine here.
- Fine salt: Don’t skip it. It keeps the brownie from tasting flat and helps the chocolate taste more “brownie-like.”
- Baking powder: Just a little helps the skillet brownie set up nicely without turning cakey.
Wet Ingredients
- Unsalted butter: Melted butter keeps this old-fashioned and simple. If you only have salted butter, use it and just go a bit lighter on the added salt.
- Granulated sugar: This is what gives you that classic shiny top and the chewy bite around the edges.
- Eggs: Room temp is easier to whisk in and gives you a smoother batter. If you forget, just set them in warm water for a few minutes.
- Vanilla extract: I like a full vanilla flavor in brownies, even when they’re very chocolatey.
Mix-ins
- Semisweet chocolate chips: Semisweet is my go-to here. You can swap in chopped dark chocolate if you want bigger pockets of melted chocolate.
- Walnuts: Totally optional, but I like the crunch. Pecans work too, or just leave the nuts out for a classic chewy skillet brownie.
For Serving
- Vanilla ice cream: This is the easiest way to serve it, especially if the brownies are still warm.
- Powdered sugar: Optional, but it looks nice if you’re serving this for company.
Recipe Instructions
- Preheat the oven: Heat the oven to 350°F. Lightly grease a 9-inch cast iron skillet with butter or nonstick spray, then set it aside.
- Whisk butter and sugar: In a mixing bowl, whisk the melted butter and sugar until it looks glossy.
- Add the eggs: Whisk in the eggs one at a time until the batter is smooth and slightly thickened, then whisk in the vanilla.
- Add the dry ingredients: Sift in the flour, cocoa powder, salt, and baking powder. Fold just until you don’t see dry streaks.
- Fold in mix-ins: Fold in the chocolate chips and walnuts (if using) until they’re evenly mixed through.
- Spread the batter: Scrape the batter into the skillet, spread it evenly, and smooth the top.
- Bake: Bake for 22 to 28 minutes, until the edges are set and a toothpick in the center comes out with moist crumbs.
- Cool: Let the brownies cool in the skillet for 15 to 20 minutes so they can set up before slicing.
- Serve: Slice and serve warm, topped with vanilla ice cream or a little powdered sugar if you want.
Some of my tips!
This is the part that really makes a difference. If you only read one section, make it this one because this is where I share the little trick that helps the recipe turn out so well.
Recipe Tips & Tricks
Don’t overbake it. Pull it when the edges look set and the center is just barely set. The middle will keep firming up as it cools in the skillet.
Use an 8-inch skillet for thicker brownies. It makes a taller, more dessert-bar style brownie. Plan on adding about 2 to 5 minutes to the bake time.
Sift the cocoa and flour. Cocoa can clump, and sifting keeps you from having little dry pockets in the finished brownies.
Fold the batter gently. Once the dry ingredients go in, I stop whisking and switch to folding. It keeps the texture fudgy and not tough.
Add espresso powder if you want deeper chocolate flavor. One teaspoon is enough to boost the cocoa without making it taste like coffee.
Make some touches!
There are plenty of easy ways to serve this depending on the occasion. Keep it simple, or add a few small touches to make it feel a little more special.
Serving Suggestions
- Ice cream: Serve a warm slice with vanilla ice cream on top. The skillet keeps the brownie warm longer, so it’s great for brownie sundaes.
- Chocolate sauce: A drizzle of chocolate sauce or hot fudge is a little extra, but it fits the old-school vibe of this dessert.
- Fresh berries: Strawberries or raspberries are nice on the side. I like them when the brownie feels especially rich.
- Whipped cream: A spoonful of lightly sweetened whipped cream works if you don’t have ice cream. Add a pinch of salt on top if you like that sweet-salty thing.
Save it for later
This section covers how to store leftovers and what parts of the recipe you can prepare ahead of time.
Storage and Make Ahead
Store it covered at room temperature for up to 3 days. I usually just cover the skillet tightly, or move slices to a container if I need the pan back.
If you want it to last a little longer, refrigerate it for up to 5 days. The center will firm up more in the fridge, which is normal.
For serving, I like to warm slices briefly in the microwave so the chocolate chips soften again. You can also warm the whole skillet in a low oven for a few minutes.

Recipe FAQs
How do I know when skillet brownies are done?
Look for set edges and a center that’s just barely set. A toothpick in the middle should come out with moist crumbs, not wet batter.
Can I use a different pan if I don’t have a cast iron skillet?
Yes. A 9-inch cake pan or an 8×8 baking pan works, but you won’t get quite the same crisp edges you get from cast iron. Keep an eye on the bake time since different pans can run a little faster or slower.
Can I swap the chocolate chips for chopped chocolate?
Definitely. Chopped dark chocolate gives you bigger melted pockets, which I really like in this recipe. Just keep the amount about the same as the chips.
Why did my brownies turn out cakey?
Usually it’s from baking a little too long or overmixing after adding the dry ingredients. Pull them sooner next time (even if the center looks slightly underdone), and fold the flour/cocoa in just until combined.
Can I leave out the nuts?
Yes, you can skip them completely. The brownies will be a little more chewy and uniform, which is classic and honestly my default most of the time.
