Silpat is the original silicone nonstick baking mat. A must for every home baker and professional too. Line your sheet pan with the silpat and nothing sticks! No greasing necessary. The half sheet size (12x18) fits a standard sheet pan. Roll out your sugar cookie dough directly on a Silpat. Cut out your desired shape and remove dough scraps . Slide the silpat onto your pan and bake. Cookies aren't handled and don't get misshapen. Kosher certified.
