Embossing mat
From Infogalactic: the planetary knowledge core
An embossing mat is a tool for decorating cakes. It creates embossed effects on the top of cakes, cupcakes, or similar items. The user presses the mat down into cake dough or icing and the pattern embossed in the mat is transferred to the item. Embossing mats are often made of silicone rubber or similar flexible polymers.[citation needed]
