Sheet pan cookies are one of my favorite ways to make cookies, especially when I am baking for a crowd! These Double Chocolate Sheet Pan Cookies are thick, chewy, and loaded with rich chocolate flavor in every bite. Best of all, there is no scooping required; just press the dough into the pan, bake, and slice into however many cookies you’d like. No judgment here on how big your “cookies” are! 😉
If you have tried my Sheet Pan Chocolate Chip Cookies, you already know how easy this method is. This chocolate version takes that same simple approach and turns it into a rich, bakery-style cookie loaded with Dutch-process cocoa and plenty of chocolate chips and chunks. The result is a thick, chewy cookie with soft centers and slightly crisp edges that is perfect for sharing (or keeping all to yourself!).
Ingredients & Substitutions
- Butter: Melted unsalted butter gives these cookies their chewy, bakery-style texture.
- Sugars: A combination of light brown sugar and granulated sugar adds sweetness while keeping the cookies soft and chewy.
- Dutch-Process Cocoa Powder: Dutch-process cocoa gives these cookies a rich, deep chocolate flavor. I don’t recommend substituting natural cocoa powder, as it will change both the flavor and the texture.
- Cornstarch: A little cornstarch helps make the cookies extra soft and tender.
- Chocolate Chips & Chunks: I love using a mix of dark chocolate chips and chunks for plenty of chocolate in every bite. If you only have chocolate chips or only chocolate chunks, feel free to use all of one or the other. Semi-sweet chocolate also works well.
FAQs
Can I use a different size sheet pan?
This recipe is written for a 15x10x1-inch sheet pan. Using a different size pan will change the thickness of the cookies and may require adjusting the baking time.
Can I use a different type of cocoa powder?
I recommend using Dutch-process cocoa powder for the best rich chocolate flavor and texture. Natural cocoa powder will work in a pinch, but it may slightly change the flavor and color of the cookies.
How do I know when the cookies are done?
The edges should be set while the center still looks slightly underbaked. The cookies will continue to set as they cool, which helps give them their soft, chewy texture.
Can I use a different type of chocolate?
Absolutely! Dark chocolate gives these cookies a rich flavor, but milk chocolate, semi-sweet chocolate, or a mix of chocolate chips and chunks will also work well.
Can I add mix-ins?
Yes! These cookies are easy to customize. Try adding chopped walnuts or pecans, peanut butter chips, white chocolate chips, toffee bits, or even mini marshmallows. Keep the total amount of mix-ins close to the amount of chocolate in the recipe so the cookies bake evenly.
Why You’ll Love These Sheet Pan Cookies
- No scooping required! Instead of portioning out individual cookies, you simply press the dough into a sheet pan and slice once cooled.
- Perfect for a crowd: One pan makes plenty of thick, chewy cookies, making them great for parties, bake sales, or sharing.
- Bakery-style texture: The melted butter, extra egg yolk, and cornstarch help create soft centers with slightly crisp edges.
- Deep chocolate flavor: Dutch-process cocoa gives these cookies a rich, chocolatey flavor, and the combination of cocoa, chocolate chips, and chunks makes every bite extra chocolatey.
How to Store Double Chocolate Sheet Pan Cookies
To Store: Store the cookies in an airtight container at room temperature for up to 3 days. To help keep them soft and chewy, avoid leaving them uncovered.
To Freeze: These cookies freeze well! Once completely cooled, cut them into squares and place them in a freezer-safe container or bag. Freeze for up to 3 months. Let them thaw at room temperature before serving.
