Preheating is essential for evenly baked cookies. Set your toaster oven to bake at 350°F before preparing the cookies. This allows the oven to heat to the proper temperature fully.

For the best results, line your baking sheet with parchment paper or a silicone baking mat before adding the cookie dough. This prevents sticking and creates an even heating surface. If you don't have lining material, grease the sheet lightly with butter, shortening, or non-stick spray.

Use a small cookie scoop or spoon to scoop rounded balls of dough onto the prepared baking sheet, spacing them at least 1 inch apart. This allows for maximum airflow and even baking. The toaster oven sheet should fit 5-6 cookies.

Place the loaded cookie sheet into the preheated toaster oven. Bake cookies in toaster oven for 8-10 minutes, keeping an eye on them near the end. Due to the direct top heat, toaster ovens often bake faster than traditional ovens. The cookies are done when the edges are lightly browned.

Remove from the oven and allow the baked cookies to cool on the sheet for 5 minutes before transferring to a wire rack to finish cooling. Be sure to let the pan cool fully before repeating to bake another batch.
