How to bake cake evenly: preventing the dreaded dome

When you bake a cake does it sometimes peak into a big dome on top, instead of staying nice and flat? Frustrating, isn’t it? Learning how to bake cake evenly can be a challenge.

True, beauty is only crust deep, and sometimes you don’t care if your cake is convex rather than flat across the top. But have you ever tried to stack two or three domed layers atop one another? Right. They wobble, they slip and slide, and inevitably you wind up with an off-kilter cake.

Sure, you can trim off those domes to make perfectly flat layers. But think of all that good cake you’re wasting. Even if you snack on it rather than tossing it, as most of us do, better it should remain part of the whole!

No, your best tactic to bake cake evenly relies on simple thermodynamics: once you put the cake into the oven, you have to keep the batter at the edges of the pan from baking too quickly.

Cake layers that dome as they bake are a challenge to stack and frost. Here’s an easy way to bake cake evenly. Click To Tweet

Here’s the deal: As batter bakes it does two things — rise, and lose moisture. When enough moisture is lost the cake solidifies (or “sets”) and stops rising.

This happens quickly around the edges of the pan; much less quickly in its interior, where the bulk of the batter has created its own insulation. So the cake’s edges rise and set quickly; but the slower-baking center continues to rise, often far above the edges: thus the dome. Large or small, it can be irritating; but thankfully, avoidable.

In order to bake cake evenly, you have to insulate its edges. Preventing the temperature of batter at the edge from increasing quickly allows the cake to rise longer before it sets. A cake whose edges rise at nearly the same rate as its center will remain flat across the top — no dome, perfect for stacking and icing.

Enter cake strips, the simplest way by far to bake cake evenly. Soak the strips in cold water, fasten them around the outside of your pan with their built-in Velcro, and voilà! Instant insulation.

Sure, you can probably fashion your own insulation with strips of cotton towel, and then safety-pin them around the pans. But honestly? Save yourself the hassle. Here’s what one of our satisfied customers says:

“These are the BEST! Since I frequently make 3-layer cakes, I ordered 2 sets. These are very easy to use. Just soak them in water for 15 minutes, wrap them around the pans and secure with the Velcro. No safety pins needed! The strips keep the cake layers from getting a dome, so it’s easier to fill and frost them.” — Mary Ellen, Oak Harbor, Ohio

Let’s see just how cake strips work — and what a difference they make.

How cake strips work

Here are the strips; they come in a set of two, and each will fit an 8” or 9” round cake pan.

Soak in cold water before using

Soak the strips for a minimum of 15 minutes; you’ll need to weigh them down to submerge them at first. Since it’s actually the water that insulates your cake, you want the strips to be thoroughly soaked.

Fasten around the edge of your pan

Velcro lets you easily fit the strip to your particular 8″ or 9″ round pan.

Bake the cake

Remove the strip as soon as you can safely handle it; it’ll cool down quickly.

Remove the cake from the pan, and cool it on a rack. Stack and frost as desired.

Here’s a tip from my fellow blogger, Chef Susan Reid: “The best-looking frosted cakes are placed on a plate so the flat bottom is facing up. Often the slight curve even on the flat cake nestles just right inside the concave surface of any typical plate you’d put it on.”

See the difference?

The half-cake on the right, baked without a strip, has shorter edges and a taller center: it domed. The cake on the left, baked with a strip, rose evenly all the way across.

In addition to preventing doming, using a cake strip prevents the edge of the cake from overbaking. The darker ridge around the top of the half-cake at right, baked without a cake strip, is tough and chewy. The half-cake on the left, baked with a strip? Soft and tender.

So go ahead: spread that frosting, stack those layers. Now that you know how to bake cake evenly, using cake strips, there’s no going back to the hassle of trimming and leveling.

Some bakers say they’ve had luck simply pressing down any dome on their cake as soon as the cake comes out of the oven. I tried that, but the dome remained; it just sprang back. If you espouse this manual flattening, we’d love you to share how you do it in comments, below.

    Would buying 2 sets of cake strips be enough to use on the sides of an 9″ x 13″ rectangle pan work? I make a lot of this size cake and it always domes in the middle for me.

      Sharon, one set, the two strips velcro-d to one another to make one long strip, makes a large enough strip for a 9″ x 13″ pan, with some to spare. Works like a charm! PJH@KAF

    I use the cake strips and I loce the results for a even rise, level layer with no dome. So simple to use and so effective…love my cake strips!

    I’m not really a layer cake baker-but I bet this would also work for making brownies or cornbread. I imagine the strips could fit around a square pan too?

      Karin, each strip is 30 1/2″ long; and then you need a bit at each end for the velcro strips to meet. So one wouldn’t be quite long enough for an 8″ square pan, though you can velcro them to one another to make one long strip. And yes, I think it would work just fine for anything that tends to dome. Good luck — PJH@KAF

    I read that using a 3″ tall pan instead of a 2″ tall pan will prevent doming. PJ, what are your thoughts on this?

      I can’t see the scientific basis for that; you’re still going to have the same issue with heat reaching/setting the sides of the batter before it reaches the center. But if you test the theory, let us know how it goes, OK? PJH@KAF

      Yes, Nana, you can attach the two strips together to make one long strip, which will fit nicely around a 9″ x 13″ pan. PJH@KAF

    If you don’t have the insulated cake strips, just lower the oven temperature, a bake a little longer.

    I don’t know if I’ll ever use them but I want to thank you for a fond memory that I’d forgotten about. My mom went through different phases and one was a cake phase. I remember her taking strips of towels & soaking them in water and wrapping them around the pans. I never knew why, now I do. Mom’s gone now so thank for bringing a smile to my face.

    I have strips like this I bought years ago, and they work like a charm. Well worth the investment, but mine need to be pinned. I wish mine had velcro!

      Why couldn’t you sew some Velcro strips on them. Mine also are the pin type. I have been using them many many years and they really work. I just hate crooked cakes and these strips make the layers level. Good luck
