Chocolate Sheet Pan Cake

This Chocolate Sheet Pan Cake is rich, moist, and perfectly chocolatey—baked in one pan for an easy, no-fuss dessert that feeds a crowd. The tender crumb stays soft and decadent, while a smooth chocolate frosting melts right into the warm cake for that classic, irresistible finish. Made gluten-free with clean, simple ingredients, it’s the kind of dessert that’s just as perfect for birthdays as it is for casual weeknights. Simple, nostalgic, and always a favorite.
