We all use round springforms. Why not a square one? The 9" square pan is perfect for brownies, square cakes, tortes, tartes, sticky buns, bar cookies, and, of course, cheesecakes. It combines Kaiser's heavy duty La Forme quality with the latest nonstick technology and a scratch-resistant enamel surface that allows you to cut right in the pan without damaging the surface. Its two-layer interior and exterior eliminates the need for flouring pans. And with the even and gentle heat distribution that characterizes this bakeware, you are assured of baked goods with a smooth crumb. It is not affected by acidic or citrus foods and allows for easy release when lightly coated with butter or oil. I generally butter the pan and stick it in the frig during preparation, then fill it and bake. By doing this, I find it releases that much better.
Kaiser offers a 10-year warranty on the pan and a lifetime warranty on the springform buckles.
