Can I bake a cake in a cookie sheet pan?

I’ve tried this a few times, and while you can bake a cake in a cookie sheet pan, it’s important to note that cookie sheet pans are usually shallower than standard cake pans. That means the batter spreads out more and may bake faster. For a cookie cake like this recipe, a shallow pan actually works in our favor because it creates that golden edge and soft, chewy center I love so much. Just keep an eye on the baking time!

What is the difference between a cookie sheet and a sheet cake pan?

I used to get confused about this too. A cookie sheet typically has low or no sides, while a sheet cake pan has taller sides to contain more batter. Using a cookie sheet for a cookie cake is perfect because we want a thin, even layer that cooks quickly and has soft edges. It’s all about the texture you’re aiming for.

Can you bake cookies in a sheet pan?

Absolutely. In fact, that’s exactly what this recipe is—a giant cookie baked in a sheet pan. The trick I’ve learned is to spread the dough evenly and watch the edges closely. You get the convenience of a large cookie with the same soft, chewy texture of individual cookies, and it’s way easier to serve a crowd.

How is a cookie cake different from a cookie?

This is one of my favorite things to explain because it’s subtle but impactful. A cookie cake is essentially a giant cookie baked all at once, often soft in the center with a slightly crisp edge, and meant to be sliced and shared. Regular cookies are smaller, baked individually, and often have more variation in texture. Making a cookie cake feels celebratory, almost like turning a simple cookie into a dessert centerpiece, which is why I love baking this recipe for birthdays, parties, or just an indulgent treat at home.

Add Dry Ingredients: In a separate bowl, whisk together flour, baking soda, cornstarch, and salt. Fold into wet ingredients until just combined.
