Input:
I have to say I am very impressed with these silicone cupcake molds. I have always used paper ones and, being a mom, it gets messy and expensive every time we want to bake cup cakes (which is every weekend). I've also tried not using any molds and it only makes a bigger mess. When I found these I was excited. They are economical and convenient being able to reuse them each time. They don't melt, they are durable, and makes perfect average sized cupcakes and muffins. I especially love the bright colors and how well made they are. It has definitely made things a lot easier for us. I am truly  happy with my buy and I highly recommend this product to everyone I know. Bring it on P.T.O. I am a cupcake making machine now!
