What is an insulated cookie sheet made out of?

Insulated cookie sheets are typically made of aluminum with a layer of silicone on the bottom for insulation.

Here's a breakdown:

* Aluminum: This is the main material for the sheet itself. It's a great conductor of heat, ensuring even baking.

* Silicone: This is a heat-resistant material that acts as an insulator. It prevents the bottom of the sheet from getting too hot, which can lead to burnt cookies.

Some insulated cookie sheets might also include additional layers of insulation, such as:

* Heat-resistant plastic: This can be used as an extra layer of insulation between the aluminum and the silicone.

* Foam: This can be used to create a more substantial insulation layer, especially for thicker sheets.

Ultimately, the specific materials used in an insulated cookie sheet will vary depending on the manufacturer. However, the basic principles remain the same: aluminum for heat conduction and silicone for insulation.
