Square Cake Forms

Square cakes are the hardest finish to frost by hand — crisp corners take even professionals years to master. The Square Cake Form Kit does the geometry for you: stack your layers in the food-grade silicone liner, pour softened buttercream into the gap, chill, and peel away sharp, perfectly straight corners. Available in 6-inch and 8-inch sizes, with free US shipping and 30-day returns.
