Is Aluminum Safe for Baking?

You can find numerous articles on what type of pan you should use to bake cakes. I can tell you, I’ve used them all – old, new, black, silver, glass, cheap, expensive . . . and I’ve made nice cakes with all of them. But they’re all different, and if you find yourself switching back and forth between this type and that type, you’re going to drive yourself batty.

In addition, there’s the question of aluminum.  Is aluminum safe for baking?  Are aluminum pans safe? I’ll deal with that in this article as well.

My favorite cake pans are the high-quality, anodized aluminum pans. The silver color reflects heat. A darker pan absorbs heat, and will actually require an adjustment on the temperature – down about 25° F.

Glass pans retain heat for much longer (as you know if you’ve ever burned your hand on a glass casserole that you took out of the oven 40 minutes ago, thinking it had cooled . . . oops.)  If you bake in glass, you need to account for the additional baking time that will occur after you take the pan out of the oven, or you’ll end up with a very dry cake.  Also, I find glass pans to be so much heavier and harder to store.

Steel pans have a tendency to change color as they age – turning much darker as the surface oxidizes. The darker the pan, the more heat it will absorb during baking.  Again, if you don’t account for that, the result is a dry, overbaked cake.

Baking in aluminum – especially quality aluminum – will take some of the variables out of baking equation.  The pans cool quickly, so you can be more precise with your oven timing.  The anodized surface is very hard and will not oxidize (rust) like a steel pan.  And the shiny surface reflects heat consistently – so you can be confident the next time you have a surprise event that calls for a great cake in a hurry.

But is aluminum safe for cooking?  

In college, I majored in chemistry and physics. I was a science fair nerd all through high school and picked up a lot of science techniques, and followed that interest through college. So I do have a background that allows me to focus on the science of aluminum, and not the hype and hysteria you often see in the supermarket checkout line. So here are the facts:

Aluminum is the third most common element on earth.  You ingest aluminum daily – simply because it’s so prevalent in the soil and dust we walk on and breathe.  But to ease the mind of bakers everywhere, Cook’s Illustrated ran a test in 2012.  Using acidic tomatoes, they cooked a tomato sauce for two hours, then stored the sauce overnight in the same aluminum pot.  The next day, the sauce was measured to contain just .0024 milligrams per cup.  In comparison, a cup of hot tea can contain 200 times that much aluminum . . . and a single antacid chewable can contain 80,000 times as much!

In addition, greasing and flouring a pan further reduces the actual contact between the batter and the pan itself, so you’re safer there as well.  And many bakers line their pans with parchment paper, eliminating contact completely.

Considering the benefits of aluminum pans and the much greater impact of the natural environment on our aluminum intake, I have no problem using and recommending aluminum bakeware.

I recommend collecting a full set of high-quality anodized aluminum baking pans.  Check out my article on the best baking pans here.  They’ll last for a lifetime and provide many hours of enjoyment for you and your family.

  1. Thanks for the great info. I don’t bake, but it might be handy to have a set of pans just in case I ever get the urge. Thanks for providing me a link to buy them too. Awesome!
