Subway Chocolate Chip Footlong Cookie Copycat Recipe
This Subway chocolate chip footlong cookie is the giant, gooey slab of a dessert that’s been taking over social media feeds, and now you can make one at home for a fraction of the price. It bakes up in a standard 9×13 inch pan, feeds a crowd, and takes about 30 minutes from start to finish.
The edges go crisp and golden while the center stays thick and soft. It’s the kind of thing you cut into slabs at the table and watch disappear.
Why I Love This Recipe
The brown butter is what makes this one worth repeating. It adds a nutty, almost toffee-like depth that a standard melted-butter cookie just doesn’t have.
The dough comes together in one bowl, no mixer needed. That matters on a weeknight when you don’t want a production.
This is the version I keep coming back to when I need something crowd-pleasing and fast.
Recipe Ingredients
- 2 sticks (227g) unsalted butter – Browned for deeper flavor; salted works too, just skip the added salt
- 1 cup (200g) granulated sugar – Gives the edges their crisp snap
- 1/2 cup (110g) light brown sugar, packed – Adds moisture and a mild caramel note
- 2 large eggs – Brings the dough together; use room-temperature eggs for even mixing
- 1 tsp vanilla extract – Plain vanilla, not paste; paste can make the dough slightly streaky
- 2 1/4 cups (280g) all-purpose flour – Spooned and leveled, not scooped, to avoid a dense result
- 1 tsp baking soda – Helps the cookie rise and spread evenly
- 1 tsp fine salt – Skip if you used salted butter
- 2 cups (340g) semi-sweet chocolate chips – Subway uses a generous, uneven distribution; go heavy-handed
Variations / Substitutions
- Brown butter swap – If you skip browning and just melt the butter, the cookie will still be good but the flavor will be noticeably flatter.
- Dark chocolate chips – Use 60 to 70% dark chocolate chips for a less sweet, more bittersweet result that works well with the brown butter.
- Milk chocolate chips – Swapping to milk chocolate makes this sweeter and more candy-like, closer to a classic toll house style.
- Gluten-free flour – A 1:1 gluten-free all-purpose blend works here; the cookie will be slightly more crumbly at the edges.
- Reduce sugar – Cutting each sugar by 2 tbsp gives you a less sweet cookie with slightly less crisp edges.
- Flaky sea salt finish – Scatter flaky sea salt over the top right before baking for a salty-sweet contrast on every bite.

How To Make Chocolate Chip Footlong Cookie
Step 1: Brown the Butter
Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper. Place the 2 sticks (227g) unsalted butter in a light-colored saucepan over medium heat, stirring occasionally.
After about 5 to 7 minutes, the butter will foam, then the foam will subside, and you’ll see golden-brown specks settling on the bottom of the pan. That’s the milk solids toasting, and that’s exactly what you want. Pull it off the heat immediately and pour it into a large mixing bowl so it stops cooking. Let it cool for 10 minutes before you add the sugars.
Don’t walk away during this step. Butter goes from browned to burnt in under a minute, and a light-colored pan lets you see the color change clearly.
Step 2: Mix the Dough
Add the 1 cup (200g) granulated sugar and 1/2 cup (110g) packed light brown sugar to the warm brown butter and whisk until combined, about 1 minute. Add the 2 large eggs and 1 tsp vanilla extract, and whisk again until the mixture looks slightly glossy and thickens just a bit, about 30 seconds.
Switch to a spatula and fold in the 2 1/4 cups (280g) all-purpose flour, 1 tsp baking soda, and 1 tsp fine salt. Stir until no dry streaks remain, then fold in 2 cups (340g) semi-sweet chocolate chips. The dough will be thick and a little greasy-looking from the butter; that’s normal.
Don’t overmix once the flour goes in. Stir only until the flour disappears or the cookie can turn tough.
Step 3: Spread the Dough
Scrape the dough into your prepared 9×13 inch pan and use your spatula or damp fingers to press it into an even layer. Get it as flat as you can, all the way to the corners, so it bakes evenly.
The layer will look thinner than you expect, roughly 1/2 inch thick across the pan. That’s right. It puffs up during baking and the center will end up soft and thick.
Step 4: Bake the Cookie
Slide the pan into the preheated 350°F (175°C) oven and bake for 20 to 24 minutes. The edges should be deep golden brown and set firm, while the center will still look slightly underdone and matte rather than shiny.
Pull it out at the 20-minute mark and gently press the center with your finger. If it feels like wet batter, give it 2 more minutes. If it has just a little give, like a brownie center, it’s done. It firms up considerably as it cools, so pulling it early gives you that soft, Subway-style interior.
Step 5: Slice and Serve
Let the cookie cool in the pan for 15 minutes, then lift it out using the parchment paper and set it on a cutting board. Cut it into long rectangular slabs or squares, scatter a small pinch of flaky sea salt over the top if you like, and serve warm.
The edges will be crisp and snappable, the center will be soft with a slightly fudgy pull, and the chocolate chips closest to the surface will have gone slightly caramelized and dark. Serve it on the parchment so everyone can see the whole slab before you cut.
Recipe Tips
- Use a light-colored pan if you have one. Dark metal pans run hotter and can overbake the bottom before the center sets; if a dark pan is all you have, check at 18 minutes.
- Spooning and leveling the flour matters here. Too much flour makes a dry, cakey slab rather than a chewy one. Spoon it into your measuring cup and level it off with a knife, or better yet, weigh it.
- The 10-minute butter cool is not optional. Adding eggs to butter that is still very hot will scramble them. Feel the bowl; if it is warm but not hot, you are fine.
- For extra thick slices, use an 8×8 inch pan and add 5 to 8 minutes to the bake time, checking for the same visual cues.
Bake times by pan size (at 350°F / 175°C):
| Pan Size | Cookie Thickness | Bake Time |
|---|---|---|
| 9×13 inch | ~1/2 inch | 20 to 24 mins |
| 9×9 inch | ~3/4 inch | 24 to 28 mins |
| 8×8 inch | ~1 inch | 28 to 33 mins |
How To Store
- Refrigerate – Store slices in an airtight container for up to 5 days. Place parchment between layers so they don’t stick together.
- Reheating – Warm individual slices in the microwave for 15 to 20 seconds to bring back the soft, just-baked texture.
Frequently Asked Questions
Can I make the dough ahead of time?
Yes. Press the dough into the pan, cover tightly with plastic wrap, and refrigerate for up to 24 hours. Bake straight from the fridge, adding 2 to 3 minutes to the bake time.
Can I freeze the baked cookie?
Yes. Wrap individual slices in plastic wrap, then place in a zip-lock bag and freeze for up to 2 months. Thaw at room temperature for about an hour or reheat from frozen in a 300°F (150°C) oven for 8 minutes.
My center came out raw even after 24 minutes. What went wrong?
Your oven likely runs cool. Use an oven thermometer to check the actual temperature, and next time add 3 to 5 minutes. The center should feel like a set brownie, not wet batter, before you pull it out.
Can I use melted coconut oil instead of butter?
You can, but the flavor changes significantly. Coconut oil won’t brown the same way, so you’ll lose most of that nutty depth, and the texture will be slightly greasier. It works as a dairy-free option if needed.
