I bought these cake pans expecting the same ease of use as silicone cookie sheet sheets like the Silpat®, to which I have never had anything stick.

These pans actually recommend that they be sprayed with a baking spray. I skimped a bit the first time and my cake stuck. You really need to spray it as much as you would any other pan. Even so, these pans are not completely nonstick. I still have to run a knife along the edge, sometimes cutting through stuck material. These pans circumvent the need for lining the bottom with parchment paper but not the need to grease the pan.

One important note is that since they are so floppy, they need to be handled differently when removing from the oven. While they have nice broad brims, grabbing them solely by this edge may cause the pan to twist or deform, cracking the cake when it is most delicate--right out of the oven. You need to either use a peel like a flat metal cookie sheet or slowly push it onto another flat surface before removing.

With all that said, they stand up pretty well without needing special care. They wash easily in the dishwasher or by hand and do not warp in shape. Burnt material comes off readily. They are fairly cool to the touch right out of the oven, and their floppiness helps in releasing the bottom.

These pans could be improved if they were made of material more like the Silpat, making them more non-stick. They would also be more versatile if they shipped with a removing metal ring or pan that it would sit within, giving it rigidity when handling into and out of the oven.

I used my new Kitchenaid 9" round cake pans today and they work great!! I lightly sprayed them with Pam cooking spray that contained flour. They bake beautifully without any attempt to stick. I placed the silicone pans directly on the oven cooking rack without the use of a baking sheet. They sat perfectly level on the oven rack. Taking them out of the oven is a breeze. The cake pans cool quickly and were easy to handle. They have a wide brim that allows you to hold the pans securely. I love these pans! I have ordered the Heart shaped and Square pans. Get these pans while they are cheap in price. You can not go wrong. Use Pam spray and your cakes will pop out like mine without any trouble. Also, these pans will interlock inside one another for easy storage.
