How do I get the tiers so straight?
One of my tiers seemed larger. Why?
A raspberry poked through the side!
There was a crack [horizontal or vertical] on the side of mine. How do I prevent this?
Syrup was leaking out the bottom. Does this happen to you? [Yes, it has.]
My cake tiers always seem to be of uneven size when I really want them even.
[Dark Chocolate/Berry] Filling was showing through the side of my white wedding cake.
My cake seemed to shift and the top half "slid" to the left. Why did it do that?

Through all the cakes I've done, just about every disaster has occurred and everything that could have happened has happened. Luckily, I've learned greatly because of them, and without them could not have been able to teach others as effectively and answer all the why's and what if's. While the culinary school I graduated from had a great bakery department back in 1992, Western Culinary Institute was just seemingly emerging from Horst Mager Culinary Institute and had a very strong cooking backbone, and had no specialty cake decorating classes. Working at the Ritz-Carlton Laguna Niguel gave me opportunities to learn all about pastry art and design once I decided that Pastry was my field of choice.

One opportunity, as a very young scrub, I had the fortunate chance to work under and with a very talented Pastry Chef who was also an established artist and a former culinary instructor who didn't mind me coming in early or staying late on my own time doing all my experiments, and who encouraged me at the very start to take notes, notes, notes and read, read, read. Two, working at a large hotel, you are NEVER shorted on work to do and the clientele ALWAYS has a variation to whatever is in the cake book or a picture brought in, so the repetitions and variations are virtually endless.

While there are pastry artists who take the design of the cakes to the next level, have been schooled in the art of cake deco and sugar paste or who literally can create a gum paste orchid perfectly with their eyes closed, for everyone it really all starts with a plain cake, a filling, and a frosting or buttercream.

You may have a better way to build your cakes, but through trial and error here are my tips and guidelines that help prevent many of the questions and problems at the beginning of this article. The guidelines below also will help with the basic goals I've come up with for any finished cake:

Goals of a Finished Cake

1. Sides straight and even
2. Tiers evenly spaced, not just in diameter in proportion to the others, but even heights and pillar spacing
3. No cake layers/fillings, or spreads/berries, or internal garnishes, or cracks showing up or through the final coating

There are four basics of building a cake: the cake itself, fillings, syrups and the internal garnishes, tier assembly, and first and final coats.

Basic One: The Cake

• Have a cake that is firm, not 'hole-y' or too airy or open celled. A cake that is too soft, spongy or open celled will not be up to the task of holding the layer's filling.
• The layers must be cut evenly. This is not just meaning a perfect cut with no dips, divots or 'flaps' from the knife cuts on the cake, but having each slice from the cake being even with each other (for example if you cut an inch thick layer for the first cut, make each subsequent layer an inch; if it's 1/4 of an inch, make sure each other sliced layer is 1/4 of an inch, too). When slices are cut from the finished and decorated cake, even layers will show.
• The top and bottom of the cakes should be trimmed off. The top may be bowed inward or outward, depending on the baking, and the bottom may hold a shell or two from the eggs. This also makes sure each cake slice is uniform in color for each layer; no tell-tale brown for the top or bottom.
• Make sure there is an even spacing of the cake layer diameters; otherwise when assembled, there will be a noticeable difference in diameters between the tiers, which especially stands out when stacked (unless that is your whole intention). For example:
  • 14 x 10 x 6 = each is spaced 4" in diameter from each other
  • 12 x 9 x 6 = each is spaced 3"
  • 12 x 10 x 8 x 6 = each is spaced 2"

Basic Two: Fillings, Syrups and Internal Garnishes or Spreads

• Syrups:
  • Do not over-moisten. While moistness is key to good compliments and great eating, there is such a thing as over doing it. If too much syrup is added, it can lead to leaking on the bottom, and can make the cake layers unstable.
  • Syrups can add not only moisture to a cake but when flavored can compliment the filling or cake itself.
• Fillings:
  • Choose one that can set up if making fresh, and choose one that isn't liquid or runny when assembling or when finished.
  • Choose one that is appropriate: if the cake will be sitting out for extended periods for decorating or serving, a light whipped cream and strawberry filling will not hold up well, for example.
• Internal Garnishes and Spreads:
  • If using berries, make sure they are not so over-ripe that they seem to 'smoosh' by just looking at them. (For example, raspberries and blueberries.)
  • If cut fruit or berries are desired, do not use for a cake that will sit out for extended periods for decorations to be completed or they may weep, bleed or the juices may run.
  • If chopped bananas are being used and you have tossed them in an acidic liquid to help prevent browning (like lemon or pineapple juice), be sure they are carefully drained before putting with the fillings.
• Spreads:
  • If a spread (like preserves, jams, ganache, curds, etc.) will be used before the filling is placed or piped on the layers, make sure it is thin. You don't need much, and they are usually soft and don't readily set up on their own (except a traditional ganache). If using a very thick layer of a plain curd for example, there is a possibility a tier can 'shift' after setting up, where a layer literally slides or shifts since the filling and the cake will not adhere to it. A spread is used mostly for added flavor or color. An example of flavor would be dark chocolate ganache used with a mocha buttercream and an example of color would be raspberry jam used with a white chocolate mousse.

Basic Three: Assembly of the Tiers

• Make sure all cut layers are even, and evenly grained. If one cut layer for one of your tiers seems to be very porous, has a crack or a hole in it, it usually can be compensated for, but be wary. A bottom tier or middle tier with a heavily porous cake will not hold up to syrups or soft fillings well and will sometimes disintegrate while being cut when left on the cake table for a period of time.
• I always pipe my buttercream around my layers with a round tip, making it as tall as my filling. For large cakes, using large plain tip will suffice. This helps to keep the filling in place (not seep through layers), makes for an easy first coat and keeps the assembly straight for the tiers.
• Make sure when you add the filling you don't overfill—when the filling is thicker in the center than on the sides—because once you put your second layer (or third or fourth depending on how many layers for your finished cake tier) and press down to make even there is no place for it to go except out the sides.
• If you use a jam or curd for a spread before you add your filling, make sure it is thin and even. This is so when you pipe your buttercream around the edge, the filling doesn't shift or slide when crumb coating (or that first coating of buttercream making it all smooth and ready for the final coating).
• When all the cake layers have been cut evenly (remember, not just a perfect knife cut but each cut layer is even in height) and fillings have been put on with the same thickness, the tiers when assembled will theoretically be even as well, which is an ultimate goal for the finished product of multi-tiered cakes.

Basic Four: First Coat and Final Coat

• If you have piped the buttercream around the edges, the filling is encased and the sides will be easily straightened as they're being built.
• If your mousse is not set up yet and you still desire to use it for assembly it will be very loose when put between the layers. When this happens, instead of putting on a cake wheel and twirling to do the first coat, use an offset or straight spatula (whichever you are more comfortable using) and finish the crumb coat on the work bench: make the sides even and smooth with the buttercream and smooth out the tops. Then carefully lift and place on flat, even surface in the cooler until chilled and set.
• This may seem like a no-brainer but always put your tiers which are either finished or with their first coats ready for finishing on a flat, even surface. I've seen cakes with beautiful, even first and final coats in walk-ins—buttercream chilled and fully set, ready for decoration—only to be removed from a bumpy, bowed or uneven sheet pan and placed on a cake board or silver stand (and no surprise) it cracks. This is because the soft buttercream around the cake tiers have conformed and set up to the curvature of the uneven surface. Once it is placed on a flat surface, the cake levels out and cracks as it settles.
• You want to make your first coat as even and smooth as possible. If your tiers have shifted as they are being built, simply go around with your spatula and straighten while the buttercream is still softened (if the cakes are large or if the filling is soft, you may need to get your hands 'dirty' and manually shift to straighten the sides). If any curd or jam bleeds now when the first coat is being put on, remove any large, oozing pockets and cover with buttercream. If a berry pokes through the piping of buttercream, push it back in now before it hardens in place since it will undoubtedly show through the final coat. The key to a first coat is to ready the tiers for the final coat and decoration. You want the entire cake covered in buttercream (thin coat, just making it smooth and removing crumbs and imperfections) so that when it chills it firms up resulting in a durable surface for the finishing.
• Make sure your first coat is adequate, but not overly thick. There will be a final coat going on to finish up the cake, so it's not necessary to have, say, two inches of buttercream on the outside.
• If you are using a ganache, a butter-based or shortening icing or gelatin-and-whipped-cream in place of the buttercream, the same rules apply:
  • Use a plain tip for the piping of icing on the outside of the layers to hold in the filling.
  • Use a recipe for both the icing and filling that will firm up or set up upon cooling.
  • Make sure your first coating is straight and even.

These are the general guidelines for building any cake—whether it's for a wedding, a birthday or other occasion—that I have implemented through trial and error and experience. You may find other ways to accomplish the goals or have a quicker way to build your cakes. In any case, the object is to present a cake that tastes good and is structurally sound. All the decorating in the world will not help a cake that is cracked or split, is leaning to one side or another, hasn't been leveled out properly or given a good crumb coat, or having mult-tiers that are very varied in heights. Taking the time to do the rudimentaries properly will make time spent decorating time worth spent.
