Which Oven Rack Position for Cookies

Cookies are one of the most rack-position-sensitive things you can bake. The wrong position leads to burnt bottoms, pale tops, or cookies that spread too much before the edges set. Here's exactly where to place your cookies for perfect results every time.

The Best Rack Position for Cookies

For most cookies, use the upper-middle rack. This position provides:

• Enough bottom heat to set the base and create a slight crisp
• Good proximity to the top element for golden browning on the surface
• Balanced heat that allows cookies to spread correctly before the edges set

Why Not the Middle Rack?

The middle rack works too, and is a safe default — but the upper-middle rack tends to give cookies slightly better colour on top without risking burnt bases. For very thin or delicate cookies, the middle rack is the safer choice.

Why Not the Bottom Rack?

The bottom rack is too close to the lower heating element for cookies. The base will brown and burn before the top has time to set, giving you dark-bottomed, pale-topped cookies with an unpleasant bitter taste on the underside.

Baking Two Trays of Cookies at Once

If you need to bake two trays simultaneously:

• Use fan mode — the circulating air equalises the temperature between racks
• Place one tray on the upper-middle rack and one on the lower-middle rack
• Swap the trays and rotate them 180° halfway through baking for even results
• Reduce temperature by 20°C compared to the recipe if it specifies conventional mode

Use the Right Baking Sheet

Pan choice matters as much as rack position. Light-coloured, heavy-gauge aluminium pans distribute heat evenly and prevent burnt bases. The Umite Chef Natural Aluminum Half Sheet Pan Set (18x13 inch, 2 Pack) is warp-resistant and conducts heat evenly — the professional baker's choice for consistent cookies.

Add a Silicone Baking Mat

A silicone mat on your baking sheet creates an insulating layer that prevents the base of cookies from over-browning while the top catches up. The Amazon Basics Silicone Rectangular Baking Mat (2-Pack, 16.5x11.6 inch) is non-stick, reusable, and dishwasher safe — it also eliminates the need for greasing the pan and makes cleanup effortless.

Verify Your Oven Temperature

Cookies are very sensitive to temperature. An oven running 15°C too hot will burn the bases before the centres are set. The Oven Thermometer 2 Pack (50–300°C / 100–600°F) lets you confirm the actual temperature at the rack level before baking — essential for consistent results.

Quick Reference by Cookie Type

• Chocolate chip cookies → Upper-middle rack
• Shortbread → Middle rack (lower heat, longer time)
• Thin crispy cookies → Middle rack
• Thick chewy cookies → Upper-middle rack
• Macarons → Middle rack, conventional mode only
• Two trays simultaneously → Upper-middle + lower-middle, fan mode, swap halfway

Summary

Use the upper-middle rack for most cookies for the best balance of golden tops and set bases. Use the middle rack for delicate or thin cookies. Always use a light-coloured aluminium pan with a silicone mat, verify oven temperature, and swap trays halfway when baking multiple batches at once.
