Place a cookie sheet on an even surface such as a counter top or table. Position the silicone cupcake liners on the cookie sheet. If preferred, slip into the slots of a muffin tray. Fill the silicone cupcake liners. Using a ladle, fill the liners two thirds of the way with the prepared cupcake batter. Some liners come with a marked fill line.

Slip the cookie sheet supporting the silicone bakeware into the oven. Check the time. When using silicone liners for the first time, it’s important to watch the cupcakes carefully, as baking times may vary slightly from your normal cookware. Test the cupcakes to see if they’re done by inserting a toothpick or skewer into a cupcake that located in the center of the cookie sheet. The cupcakes are done baking when the toothpick comes out clean. [4] X Research source

Be careful. Silicone bakeware cools quickly, but it will be very hot when you first remove it.
