I have tried silicone baking cups before and didn't like them. My husband bought some cornbread mix, so I decided to buy and try these. I did make 6 cornbread muffins, but my picture shows only one because my husband ate one of them. Since previous silicone cups I tried everything stuck to them, I did put a little oil spray in the bottom of them, but they really didn't need it. The muffins easily came out of the cups with no sticking at all. To clean the cup, I put a little soap in the bottom to remove the oil I put in it, but other than this I only rinsed it in hot water and left it to air dry. There was literally nothing stuck to it.Although the description describes these cups as muffin liners, they are thick and sturdy and a muffin tin is not at all needed. I put them on a baking sheet lined with aluminum foil in case there was runover, but the cups held their shape without having to be supported by a muffin tin.Now that I have tried them, I am enthused to try them for so many ideas such as egg bites, mini frittatas, mini cakes, cheesecake bites, dinner rolls, and the list goes on. I am sure I will come up with more ideas over time. As an experienced cook and having tried so many gimmicks, I didn't expect to be so happy with this baking cups especially for the nonstick qualities and the rigidness of the cups.I would highly recommend using these baking cups instead of the throw away paper cups that require the support of a muffin tin. They are reusable and eliminate the expense of throw away paper cups. They also release the food much better than paper cups. These baking cups are also useful for use in the oven or in the microwave. In the microwave, you can easily make a quick breakfast with egg, scrambled or not, and add a little onion, bell pepper and cheese. Really, the uses are limited only by your imagination.UPDATE 01/02/24:I have used these baking cups often in the 7 months I have had them, primarily for corn muffins that my husband likes for breakfast. I use a Pam spray in them to reduce the possibility of anything sticking in them, but now and then little bits of the muffins stick in the grooves. The solution is warm water and an old toothbrush. The toothbrush makes cleaning them so much quicker and easier.I hope this review is helpful for you. I will update this review as I find new uses and if my opinion changes.
