I bought this Silicone 12 Cup Muffin Pan by Mister Kitchenware quite some time ago and it is one of my favorites.
The Silicone Muffin Cups are easy to clean and the muffins come out in one piece without getting stuck. Which does not always happen in a regular muffin form, even non-stick forms can have muffins stuck to them.
I do not like to use paper inserts for muffins, so this is perfect for me. I never grease them, or dust them with coconut flour. For me it is not necessary.
Cleaning is very simple with hot water and dishwashing liquid. I have not put my silicone forms in the dishwasher, so I do not know how they hold up.
Please let me know in the comments, if you have bought the Silicone 12 cup Muffin Pans and have different experiences.
