These Eggless Sheet Pan Chocolate Chip Cookie Bars are everything a crowd-feeding cookie should be — crispy on the edges, chewy and golden in the center, and completely egg-free by design. One bowl, one pan, 24 bars, and no scooping required. I developed this recipe after years of reader questions asking how to make my one-bowl chocolate chip cookies for a bigger group, and it’s been foolproof in every single test. This is the recipe that shows up when you need enough cookies for everyone — and it needs to be done in under an hour.
Oriana’s Thoughts On The Recipe
These bars came from a question I kept getting from readers: “Oriana, can I make your chocolate chip cookies in a sheet pan?” After enough messages, I got into the kitchen and figured it out. The answer is yes — and it’s even better than individual cookies for a crowd. One bowl, one pan, no scooping, no rotating batches. You spread the dough, you bake it, you cut it. Done in 30 minutes. Enough for a birthday party, a bake sale table, or a Tuesday when your kids invite the whole neighborhood over.
Here’s what I love most: these bars don’t taste “egg-free.” They taste like the best chocolate chip cookie bar you’ve ever had — buttery, chewy in the middle, with those golden crispy edges everyone fights over. And because they’re egg-free by design (not adapted), you don’t have to explain anything or make a separate batch. Everyone eats the same thing. That’s the whole point. Just really good chocolate chip cookies everyone can share.
Why You’ll Want to Try My Recipe
Do these work as a birthday cake alternative?
Absolutely. Frost cooled bars with vanilla buttercream and top with sprinkles for a party-ready treat that’s so much easier to serve than a layer cake. Egg-free, no slicing issues, and kids love them.
Ingredients You’ll Need, Substitutions & Notes
Scroll down to the recipe card for all the details, including measurements and instructions.
Most of these are pantry staples you already have — a few are worth a quick note.
- Butter: Use unsalted so you control the salt level. The butter gets melted, not creamed, which means this is a true one-bowl recipe with no mixer needed. Dairy-free? A butter stick (not a spread) works well — Miyoko’s Creamery and Earth Balance Vegan Buttery Sticks are good options.
- Brown sugar: The higher ratio of brown sugar to white is intentional. Brown sugar holds moisture and gives you that chewy, slightly caramel-y center. Don’t swap it for all white — you’ll lose the texture.
- Milk: Just 3 tablespoons, but it does important work here — it adds the moisture that binds the dough without eggs. Any milk works: whole, oat, almond, soy. They all give good results.
- Cornstarch: One of my favorite tools in egg-free baking. It mimics what eggs do for texture — keeps the bars tender and gives the crumb that soft, slightly dense chew rather than a dry or crumbly one.
- Chocolate: Use chunks for bigger chocolate pockets, chips for more even distribution, or a mix of both. Semi-sweet is the classic. Dark chocolate works beautifully, too. Dairy-free? Enjoy Life is widely available and soy-free.
- Flaky sea salt: Optional, but don’t skip it if you have it. A pinch on top right before baking takes these from great to really great.
Food Allergy Notes & Swaps
This recipe does not contain eggs, tree nuts, peanuts, soy, sesame, fish, or shellfish as ingredients. Manufacturing lines change — read every label every single time, even brands you have used before. That habit has never steered me wrong.
Need Dairy-Free or Gluten-Free?
If you are navigating additional dietary needs alongside the egg-free requirement, I have detailed guides for both:
- How I Replace Dairy in My Egg-Free Recipes — covers dairy-free swaps for butter, cottage cheese, milk, and shredded cheese that work in this muffin batter without compromising the texture.
- Baking Without Eggs and Gluten: How I Make It Work — for households navigating both egg and gluten restrictions, this post walks through flour substitutions without losing structure in recipes like this one.
Ingredient Swap Suggestions
- Dairy-Free: To make this recipe dairy-free, you can easily swap out the dairy ingredients for non-dairy alternatives.
- Butter: Substitute butter with dairy-free butter substitutes. Miyoko’s Creamery Organic Vegan Butter, Trader Joe’s brand vegan butter, and Earth Balance Vegan Buttery Sticks are my favorite butter substitutes for baking. For the best flavor, use a vegan butter that tastes good. Use sticks or blocks, not tub (spreadable) butter.
- Milk: You can use your favorite non-dairy milk, like soy or oat milk.
- Chocolate Chips: Use your favorite dairy-free chocolate. One of my favorites is Ghirardelli Non-Dairy Dark Chocolate Chips for Baking. Here you can find other brands I like and use.
- Gluten-Free: Use a gluten-free, all-purpose flour blend. Look for a gluten-free flour blend specifically formulated for baking, as it will have the right combination of flours and starches to mimic the texture of wheat flour. My favorite is Better Batter Original Blend. I also like Doves Farm Freee Gluten-Free All-Purpose Flour, but this blend does not contain xanthan gum, so you need to add 1/4 teaspoon of xanthan gum per cup (140 g) of gluten-free flour blend.
What I Learned Testing This Recipe
This recipe came directly from reader requests. I’d been getting the same question for months: “Can I make your chocolate chip cookies in a sheet pan for a bigger group?” So I took my one-bowl chocolate chip cookie recipe and adapted it — and honestly, it worked better than I expected on the very first test.
- The pan size matters more than you’d think. I tested with a 42×29 cm pan (about 16.5×11.5 inches), which is slightly smaller than a standard half sheet pan. The result? A bar with the perfect thickness — not so thin it’s a wafer, not so thick it turns cakey. With this pan size, 30 minutes is the right bake time. If you use a larger half sheet pan (18×13 inches), the bars will spread thinner, and you may only need 22–25 minutes.
- The other thing I learned: trust the underbake. The visual cue that works every time: the edges should be lightly browned, and the center should look set — but the whole pan does not need to be browned. If you’re waiting for the entire surface to turn golden, you’ve already gone too far. Pull them when it’s just the edges, and let the pan do the rest.

Tips & Troubleshooting
- Slightly underbake on purpose. These bars keep cooking on the hot pan after you pull them from the oven. The center should look just barely set when you take them out — not glossy or jiggly, though. Pull them when the edges are golden and the center looks almost done. They’ll firm up perfectly as they cool.
- Don’t skip the 5-minute rest after melting the butter. Letting the butter mixture cool slightly before folding in the chocolate keeps your chips and chunks intact. Warm butter melts them into the dough — good for flavor, but you lose those satisfying chocolate pockets.
- The dough is thick — that’s right. Once you add the flour, the dough will be stiff and shiny. This is what you want. Use a spatula (or slightly dampened fingertips) to spread it all the way to the corners of the pan.
- Use a plastic knife or plastic bench scraper to cut. No need to remove the bars from the pan first. A plastic knife cuts cleanly and won’t scratch your sheet pan. Let them cool completely — at least 30 minutes — before cutting, or they’ll crumble.
- My bars came out dry or crumbly. This usually means one of two things: the flour was over-measured (always spoon into the cup and level, or weigh it), or they were overbaked. Check them at the 28-minute mark and err on the side of pulling them early.
- My bars didn’t spread to the edges. The dough is stiff — it won’t spread on its own. Press it all the way to the corners with a spatula. Slightly damp fingertips help if the dough keeps sticking to the spatula.
Pan Size & Thickness Guide
This is the question most recipes don’t answer — and it’s a real one, because sheet pans come in different sizes and the thickness of your bars depends entirely on which one you use.
- Half sheet pan 17.9 x 12.9 x 1 inches (42×29.5 cm) — My tested pan: This is the pan I used for this recipe. You get bars with a nice, satisfying thickness — substantial enough to pick up and eat without falling apart, but not so thick they turn cakey. Bake time: 30 minutes.
- Half sheet pan (18×13 inches / 46×33 cm): Slightly larger, so your bars will be a little thinner. They’ll still have great texture, just more like a classic thin cookie bar. Start checking at 22 minutes.
- Want thicker bars? Make 1.5x the recipe in the same 42×29 cm pan. The extra batter gives you a noticeably thicker, more substantial bar. Add 5–8 extra minutes to the bake time and keep an eye on the center.
- 9×13 pan: If you want to cut the recipe in half, a 9×13 pan works well. Bake time will be similar — start checking around 25 minutes.
- Prefer a smaller batch? Try my Eggless Chocolate Chip Cookie Bars — made in a 9×9-inch pan, perfect when you don’t need to feed a crowd. These are thicker bars.
Storage and Freezing Instructions
Room temperature: Store in an airtight container at room temperature for up to 4 days. They stay soft and chewy — if anything, the texture improves on day two.
Freezing: These freeze beautifully. Wrap individual bars and freeze for up to 2 months. Thaw at room temperature for about 30 minutes before serving. You can also freeze the whole uncut pan, wrapped tightly in plastic wrap and foil — thaw overnight and cut the next morning.

Ingredients
- 1 cup (230 g) unsalted butter, melted
- 1/2 cup (100 g) granulated sugar
- 1 cup (200 g) light brown sugar, packed
- 1 1/2 teaspoons (6 g) kosher salt ( if using table salt reduce to half)
- 3 tablespoons (45 ml) milk
- 1 teaspoon (5 ml) pure vanilla extract
- 2 1/2 cups (350 g) all-purpose flour
- 1/2 teaspoon (3 g) baking soda
- 1 teaspoon (4 g) baking powder
- 2 teaspoons (8 g) cornstarch
- 1 1/2 cups (300 g) semi-sweet or dark chocolate chunks or chips
- extra chocolate chips for topping (optional)
- flaky sea salt for finishing (optional)
Instructions
- Prep your pan and preheat the oven: Preheat your oven to 325°F (165°C). Spray a half sheet pan (17.9 x 12.9 x 1 inches / 42×29.5 cm) generously with nonstick cooking spray and set aside.
- Mix the wet ingredients: In a large bowl, whisk together the melted butter, brown sugar, granulated sugar, and salt until smooth and no brown sugar lumps remain. Add the milk and vanilla and whisk until well combined. The mixture must look homogeneous and glossy. The mixture will look thin at this point — that's completely normal. Let it rest for about 5 minutes to cool slightly before continuing; this prevents the chips from melting into the dough.
- Add the dry ingredients: Add the flour, baking soda, baking powder, and cornstarch. Stir with a large spatula until just combined. The dough will be thick, soft, and a little shiny — that's exactly what you want.
- Fold in the chocolate: Gently fold in the chocolate chunks or chips until evenly distributed. The dough is thick, and the chocolate may take a moment to incorporate — just keep folding, and it will come together.
- Spread: Scrape the dough into the prepared pan and spread it into an even layer all the way to the corners. Top with extra chocolate chips if desired.
- Bake: Bake for 28–30 minutes. The bars will look puffy when they come out — that's normal. They will settle and flatten as they cool. Do not overbake — you want the center to still look just barely set. The edges will be slightly golden.
- Cool and cut: Let the bars cool completely in the pan, at least 30 minutes — do not cut them warm or they'll crumble. Once cool, cut directly in the pan into 24 bars using a plastic knife or plastic bench scraper so you don't scratch the pan. Sprinkle with flaky sea salt if desired and serve straight from the pan.

Variations & Additions To Try
- Mix-in swaps: Replace some or all of the chocolate chips with white chocolate chips, peanut butter chips, M&Ms, or a mix of all three. Dried cherries and dark chocolate are a great combination.
- Salted caramel version: Drizzle the warm bars with salted caramel sauce right after they come out of the oven. Let it soak in slightly before cutting.
- Birthday bar cake: Frost the cooled bars with a thin layer of vanilla buttercream and top with rainbow sprinkles. Cut into bars and serve in place of a birthday cake. Works beautifully for class parties.
- Holiday sprinkles for birthdays or classroom celebrations
Serving Suggestions
These bars are built for the moments that feel high-stakes for allergy families — the class party, the bake sale, the birthday where you need enough for everyone, and you’re working on a real-life timeline.
Cut them straight from the pan using a plastic knife. They stack well and travel without crumbling, so a tight container works perfectly for transporting. If you’re bringing them to a party or school event, cut into smaller 2-inch squares so they go further — you’ll get closer to 30–35 pieces that way.
For a simple dessert platter, arrange the bars on a cutting board, add a small bowl of flaky sea salt for sprinkling, and let people grab their own. No plates or forks required.
They’re also excellent as a base for ice cream sandwiches — cut two bars, add a scoop of your favorite ice cream, and press gently.
These egg-free sheet pan chocolate chip cookies are perfect for:
- School parties
- Bake sales
- Birthday celebrations
- Sleepovers
- Potlucks
- Holiday cookie trays
- Weekend baking with kids
- Lunchbox treats
- After-school snacks
I especially love this recipe for those last-minute moments when you suddenly realize you need dessert for a crowd and don’t have time for multiple batches.
