Does the cake tin material change how a cake bakes?

What a tin does is govern how quickly heat crosses from the oven air into the batter, and how much of it arrives as radiant heat at the surface. Aluminium conducts heat very quickly and reflects radiant heat if it is shiny. A dark non-stick coating absorbs radiant heat and gets hotter than the air around it. Glass conducts slowly but stores a lot of heat once warm, so it starts late and finishes hard. None of this is a small effect — it is routinely the difference between a pale cake and a burnt base.

Step by step

1. Look at the colour and the weight of your tin.Dark and thin bakes very differently from pale and heavy. If a recipe works for everyone else and burns for you, the tin is a prime suspect.
2. Adjust the temperature to the material.Roughly 10°C down for dark metal, 10°C up for glass and ceramic, and expect longer with silicone. Small adjustments, but they solve real problems.
3. Line the base and sides for long bakes.Parchment insulates slightly as well as releasing. In a dark tin on a two-hour bake it is the difference between a good crust and a burnt one.
4. Stand the tin on a baking tray.It evens out base heat, catches spills and makes a full tin easier to move. It also protects against a fierce bottom element.
5. Check the tin sits flat.Press each side on the worktop. A warped tin rocks, holds batter unevenly and bakes lopsided. Cheap thin tins warp permanently after a few hot bakes.
6. Match the material to the job.Metal for cakes and bread; ceramic for crumbles, gratins and anything going to the table; silicone for small awkward shapes where release matters more than browning.

Tips

• Buy tins by weight in your hand. A heavy tin is a good tin, more reliably than any other test.
• Non-stick coatings are not a substitute for lining. Line anyway for anything sticky, and the coating lasts far longer.
• Anodised aluminium is a good middle ground: it does not react with acidic batters, resists warping, and browns predictably.
• Do not put a hot glass dish onto a wet or cold surface. Thermal shock cracks it, sometimes violently.

Common mistakes

• Treating tin size as the only variable — Diameter matters, but a dark thin 20cm tin and a heavy pale 20cm tin produce visibly different cakes from the same batter.
• Using a silicone mould without a tray under it — It flexes as you move it and spills, and the batter finds its own uneven level so the cake bakes lopsided.

Alternatives

• Light heavy-gauge aluminium: The default for good reason. Conducts evenly, does not warp, browns moderately. Recipe temperatures are written assuming something like this.
• Dark or non-stick coated steel: Absorbs radiant heat, so bases and edges brown faster and can burn. Reduce the temperature by about 10°C and check earlier.
• Glass and ceramic: Slow to heat, then retains heat strongly. Good for puddings, crumbles and anything served in the dish; poor for sponges. Add about 10°C and expect a longer bake, and never move it from oven to cold water.
• Silicone: Almost no conduction, so sides stay pale and the bake takes longer. Excellent release, hopeless structure — always support it on a rigid baking tray.
• Thin cheap pressed steel: Warps in the oven, which tips the batter and gives a lopsided cake, and conducts unevenly. The single most common cause of an unexplained bad bake.
• Loose-bottomed and springform tins: Same conduction as their material, but the seam leaks thin batters and lets water in from a bain-marie. Line them and stand them on a tray.

Keeping on top of it

• Wash and dry tins immediately rather than leaving them to soak (after each use)
• Check tins for warping by pressing them flat on a worktop (every few months)
• Replace non-stick tins once the coating is scratched or flaking (as needed)
• Re-season carbon steel bread tins with a wipe of oil after washing (after each wash)
