Question: what size is the cavity?
Document: functional but not what I thought it was supposed to be. Dimensions were a little misleading - should have cavity measurements not overall pan size
This product is as advertised and arrived on time.Description did not state how large each cavity is so I purchased hoping it was large enough for my needs,It was not.It holds 2 oz of fluid.
i've said this before, these are thicker than your average silicone. nice product. this size is a bit odd, but that is my own fault for not getting out the ruler and actually thinking about the measurements before buying.
Not using it for cakes or muffins but it is the perfect size for what I need. I love using silicone cake pans and will never go back to metal!
A very smooth transaction. I use this mold for butter that I make. Its the perfect size for butter making or whatever you desire it for. Things pop right out of the mold ( which is great ).
got these for my homemade butter. They're not the same size as regular butter cubes. I think its somewhere around 5-6 TBS in them, instead of the 8 TBS. But I still like them, and they pop right out when I need one.
My husband ordered this to make his own hot dog buns. He must not considered the measurements if they are listed, because they don't even come close to hot dog bun size. I have personally never seen loaves as small as these molds before, but we are keeping it because he thinks he can use it for something.
used it for mini banana nut breads they turned out great!this mold is much sturdier than all silicone molds I had beforegreat quality!
a bit flimsy but thats an easy fix just put it on a cookie sheet and your good to go
We use the mold to make protein bars - some requiring baking and others requiring refrigeration to make. The mold works extremely well, minimal cleanup necessary.
Answer: overall tray is about 12" long. The cavities are about 1.5" deep, 1" wide and 3" long....but I found you can't fill them completely up as it will expand up and over. The tray is great for solid treats (like lady fingers or corn bread sticks) but not something you want to hollow out. I originally tried to make twinkies with this before I found an actual twinkie mold.
