The Wilton pan instructions say: "For best results, spray baking surface with non-stick spray" and "Place pan on cooling grid and cool completely....To remove baked goods, invert pan and apply gentle pressure to the bottom while gently peeling the pan away."
Needless to say I am not impressed. I am going to try again with another type of mix or homemade recipe. I might even try with a cake mix. Needless to say I am not impressed at this point!
