Once you have successfully baked your cake, you need to allow it to completely cool in the original pan for approximately 10 minutes. This will provide plenty of time for the starches that are present in the cake to gelatinize, which will ensure that the cake does not break apart when you remove it from the Square Cake Pans. You should be sure that you place your cake pan in the proper area so that it will cool appropriately. You should never place it on plastic or wood surfaces, since the heat from the pan can cause these types of surfaces to become warped.
It is also important to inform everyone nearby where you are placing the hot cake pan to cool so that they do not accidently burn themselves.
Once your cake has been able to cool for approximately 10 minutes in the baking pan, your starches will have fully gelatinized. At this point, you will be ready to remove the cake from the pan and allow it to finish cooling on a rack so that the baking process is halted and the cake does not begin to sweat in the pan. It is recommended that you allow the cake to be right side up on the cooling rack, especially if you have created a rounded top. One way that you can do this is to place a solid, flat surface over the top of your cake and then flip the pan and the cake upside-down. In some cases you will have to use a sharp knife along the edges of the pan to ensure the cake is loose before you flip it.
Once you have flipped the pan, it should be easy to remove the pan if you properly greased the pan. Now the cake will rest upside down on the flat surface. At this point, place your cooling rack on top of the cake and flip it once more. Now your cake will be the right way up and able to cool properly.
If there is any possibility that the cake is going to become stuck to the base of the cake pan when you flip it, then you need to put a cloth in your sink and pour very hot water on top of it. Once the water has drained away, place your pan on the cloth for several minutes. The heat produced by the cloth should be enough to loosen the cake and you should then be able to easily remove it.
