To use them is simple. Place the cups into your muffin pan. Fill them with whatever batter you like.
Bake them according to the directions on your mix.
These cups say they are non stick so I didn't use any non stick spray. They stuck to the cups. However, this could be because of the cake mix I used. They also didn't wash as easily as I would have liked. They are dishwasher safe, but I choose to wash them by hand. I had to wash them twice.
Overall, I think they are decent. I will continue to use them. They may work better if you use some non stick. Either way, it's still better than having to buy the paper liners.
Edited to add: I tried these cups again with some bread rolls. They worked perfectly!
