The special Silpat® Perfect Cookie mat will help you bake perfectly shaped cookies. Put your dough in the inner circles and let the magic happen! After baking, your cookies will reach the outter circles which represent the final size of your cookies. No need to use butter, grease, oils or sprays: your cookies will cook evenly and will come off easily. Forget about parchment paper and start saving: our Silpat mat is reusable and very durable. Its technology of fiberglass mesh and food grade silicone allows you to use your Silpat® countless times, and the cut corners will allow your Silpat® to fit perfectly in your baking tray.
