Why Your Baked Goods Are Burnt On One Side And Raw On The Other? 3 Ways To Fix Uneven Baking

Have you ever encountered underperformance issues with your baking tools?

I specifically set aside 2 hours on the weekend to bake chiffon cake as my kid’s breakfast for the next week, but my heart sank the second I took it out of the oven: the half closer to the oven back wall was so burnt it crumbled when touched, while the side near the door was still soft and undercooked when pressed. It felt like a waste even to throw it in the trash. I previously compiled 464,291 real user reviews related to baking, and found that 28% of negative reviews are related to this kind of “underperformance”. Whether it’s uneven browning of cookies, undercooked bottoms of egg tarts, or local charring of bread, many people think their baking skills are not good enough, but in most cases, the uneven heating of the tools is holding you back. Does that sound like you?

Why does underperformance happen? – Figure out the reason in 2 minutes

To put it simply, there are only two core problems: either the tool itself has poor thermal conductivity, or you haven’t figured out its “temper” and used it the wrong way. For example, if you fry dumplings in a thin sheet metal pan versus a thick cast iron pan, the thin one will definitely burn the bottom as soon as you turn on the heat while the top is still undercooked, while the thick cast iron pan can spread heat evenly across the entire bottom of the pan. The logic for baking trays and ovens is exactly the same. Many user feedbacks can also confirm this:

“The baking tray I bought is extremely thin. I baked cookies at 170°C for 12 minutes, the bottom was all burnt while the surface barely browned, and the whole tray was wasted” “With the same oven and same temperature, the top gets burnt when I place the tray on the upper rack, while the bottom is undercooked when I use the lower rack. I thought the oven was broken, but later I found out I didn’t test the temperature in advance, the actual temperature was 20°C higher than the set temperature”

Practical Guide to Fix Underperformance Issues

Method 1: “Level” the baking tray + preheat for buffer first, reduce temperature difference from the root

How to do it: Place the newly bought baking tray flat on the countertop first, press the four corners to check if there is warping. If the warping is obvious, return or exchange it directly, don’t make do with it; before baking each time, put the baking tray into the preheated oven and empty bake for 2 minutes, so that the overall temperature of the baking tray is uniform before putting in the ingredients; if you use a relatively thin baking tray, you can put an extra thick baking tray underneath as an “insulation base”. When baking crisp pastries and cookies, you can also lay a layer of oilcloth to buffer local high temperatures. Why it works: Just like you put a fluffy mat on a cold bench before sitting down in winter so you won’t feel icy in a certain spot. Preheating in advance and adding a buffer layer can make the heat of the baking tray spread evenly, and there will be no situation where a certain area has an excessively high temperature. Daily maintenance reminder: Do not rinse the baking tray directly with cold water after use, it is very easy to deform and warp due to thermal expansion and contraction. Let it cool to room temperature before washing.

Method 2: Reposition halfway through baking + cover with aluminum foil, compensate for the natural temperature difference of the oven

How to do it: No matter what you are baking, when it reaches 1/2 to 2/3 of the total baking time, open the oven door quickly (don’t keep it open for too long to avoid heat loss), turn the baking tray 180 degrees front to back. If the surface has already browned to your desired level, cover a layer of aluminum foil with 3-5 small holes poked on it above the ingredients. Why it works: Ovens have inherent natural temperature differences. The position near the back wall and the heating tube is 10-20°C higher than the position near the door. Turning the tray around allows both sides to be heated evenly, and covering with aluminum foil blocks the direct high temperature from the top, avoiding the situation where the surface is burnt while the interior is still undercooked.

Method 3: Calibrate temperature regularly + clean dust, prevent the tool from “drifting temperature secretly”

How to do it: Prepare an oven-specific thermometer. Before each use, place it on the middle rack of the oven and empty bake for 10 minutes to check the difference between the actual temperature and your set temperature. If the difference is more than 20°C, adjust the temperature accordingly each time you bake; wipe the food residue on the inner wall of the oven and the heating tube once a month, and do not let the vent be blocked by residue. Why it works: For most household ovens, the temperature will drift after more than half a year of use. If you set it to 180°C, the actual temperature may jump to 200°C, which of course makes it easy to burn. The residue on the heating tube will absorb and release heat locally, which will also cause the pastries next to it to be partially burnt.

How to avoid underperformance issues when purchasing?

Core indicators to prioritize

1. Baking trays: Prioritize thickness, at least 0.6mm or more. The thicker it is, the more uniform the heat conduction, and the less likely it is to deform;
2. Ovens: Prioritize models with at least 2 heating tubes on the top and bottom respectively, and those with hot air circulation function are better, which can make the internal cavity temperature more uniform.

Designs worth paying extra for

1. Choose baking trays that are one-piece molded, have no splicing seams, and come with thickened edging. They are much more durable than spliced models, and are not easy to warp after long-term use;
2. Choose ovens with independent upper and lower temperature control and enamel inner cavity. Separate upper and lower temperature adjustment is suitable for baking different pastries. The enamel inner cavity is not only easy to clean, but also has more uniform heat accumulation and conduction than galvanized ones.

Pitfall avoidance list, don’t believe these marketing slogans

• Don’t believe “ultra-thin and lightweight baking trays are easy to store”: Thin baking trays will deform after two uses, and will definitely have uneven heating, which is a complete waste of money;
• Don’t believe “small ovens under 10L take little space and can bake anything”: The heating tube of small ovens is too close to the ingredients, no matter how you adjust the temperature, it is easy to get partial charring. They can only reheat bread at most, and are not suitable for baking pastries at all;
• Don’t believe “bake directly without preheating”: Unless it is a professional model worth tens of thousands of yuan, this is just a gimmick for ordinary household ovens. Baking without preheating will definitely result in half raw and half burnt food.

Summary

Uneven heating of baked pastries is mostly not a problem with your skills. Preheating and leveling the baking tray in advance, repositioning and covering with aluminum foil halfway through baking, and calibrating the oven temperature regularly can solve 80% of the problem of half burnt and half raw food. When purchasing, prioritize products made of thick materials and with upper and lower temperature control, avoid thin baking trays and ovens with too small capacity, and you will basically not step into the pit of underperformance.
