Giant M&M Chocolate Chip Cookie Cake - Soft Baked Sheet Pan

This oversized cookie cake combines the best of both worlds with a soft, chewy texture studded with chocolate chips and colorful M&M candies. Baked at a lower temperature on a pizza pan, it creates a dessert perfect for birthdays, parties, or sharing with a crowd. The combination of butter and shortening gives it an ideal tender crumb, while the decorative M&M topping makes it as visually appealing as it is delicious. Cut into wedges like a pizza for easy serving.

FAQ

Can I use a different size pan?

You can use a large cookie sheet, but a 14-inch round pizza pan gives the best shape and even cooking for this recipe.

How do I know when it's done baking?

The edges should be golden brown and the center should look set but still slightly soft. It will firm up as it cools.

Can I freeze this cookie cake?

Yes, wrap tightly in plastic wrap and freeze for up to 3 months. Thaw at room temperature before serving.
