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.

      Bethany, that’s a good question; sometimes cupcakes dome so much it’s hard to add frosting, huh? It would be onerous to try to wrap a homemade cake strip around every well in a cupcake pan. But I think placing the cupcake pan in a larger pan of water before baking (i.e., baking in a water bath) would definitely help. Good luck — PJH@KAF

    I turn the dome top flat down on table and place cardboard & book on top to flatten the cake. It works. Very thin layer of cake sticks to table but thats ok.

    I’ve used these for years but the Velcro tab takes them into the future. Good on you! I just wanted to add that using a high quality pan (like a KA) will change your cakes too. For years I used the pans I inherited from my mom (a professional cake decorator). These were good but as ovens changed I decided my 1940s baking pans needed an upgrade too.

      Good point, Gwenn; “it takes a village” (good recipe, ingredients, pans, and cake strips as needed) to make a great cake! PJH@KAF

      No need to change the baking temperature or time, Nadia. The strips should help regulate the heat so that the outer edges bake at the same rate that the center does, all without needing to make other adjustments. You’ll want to still test your cake for doneness before taking it out of the oven, but you can expect it to take about the same amount of time. Kye@KAF

      I have been using these for years and they work great. However I do find that I have to bake the cakes 5 or more minutes longer. They are insulating the pan, after all, so it makes sense that the cake would take a little longer to bake than if no strips were used.

      Also, I WANT domes on my cupcakes. Any advice on how to make my cupcakes dome?

    3. The Baker's Hotline

      We’re glad you asked, Christina. It’s a valid point you bring up: Sometimes you do want your baked goods to dome! To get your cupcakes to rise high, try pre-heating the oven 25 degrees hotter than the recipe calls for. Let the cupcake batter rest in the pan for 10-15 minutes and then once you put the cupcakes in the oven, turn the temperature down to the temperature called for in the recipe. The initial blast of heat should help make the cupcakes rise nice and high. Check for doneness about 2 minutes early to ensure your cupcakes aren’t overbaked. Good luck and happy baking! Kye@KAF
