How to price Lambeth cakes and other piping heavy designs

Pricing · 4 min read · October 28, 2026

Lambeth cakes are everywhere right now, and they are some of the easiest cakes to underprice. A small heart cake covered in overpiping can take longer than a much bigger plain cake. If you price these by servings like the rest of your menu, the piping is effectively free, and it is the most time consuming part of the order.

Price the piping, not the size

Break the design into techniques: swags, borders, shells, drops, ruffles, dots, panels, top designs and accents. Each one has a time. The more of them a design uses, the more it costs, even on a 6 inch cake.

The best source for those times is you. Time yourself or your team on the next few Lambeth cakes, one technique at a time, on a single tier size. Write down the minutes for one line of swags, one border, one set of drops. After four or five cakes you will have reliable numbers, and they are usually higher than you guessed.

Also separate accents and top designs by how they are made. Piped flowers or bows you made ahead on a slow day cost differently from accents piped on the cake as you go. A simple top design costs differently from a detailed one.

Count the lines

Lambeth is built in layers of piping. Three lines of swags take about three times as long as one. Count how many layers each element has in the photo and price each one.

When a customer sends a photo, go around the cake section by section and write it down like this:

Top edge border: shells, 2 lines
Side swags: 3 lines, with drops below
Bottom border: ruffle, 1 line, plus shells, 1 line
Top design: detailed, centered
Accents: 8 rosettes piped on the cake

That list is your quote. It also helps when a customer wants to lower the price, because you can show exactly which element to simplify. Taking the swags from three lines to two is a clear change you can both see.

Colors add time

Every extra color means another bag, another pass and more care at the edges. Treat each added color as roughly two more lines of work, and price making colored buttercream separately.

So a swag with two lines in one color is two lines of work. The same swag with a second color is about four. Add a third color and it is about six, before you pipe anything else. Mixing and matching each colored buttercream is its own task on top of that, and deep shades like red or black often need extra time to develop.

Size still matters

A swag around an 8 inch tier is longer than around a 6 inch. Scale the time for anything that runs around the tier by its size.

The simple way is to time each technique once on one size and scale by diameter. If a border takes a certain time on an 8 inch tier, a 6 inch tier takes about three quarters of that, and a 10 inch tier about one and a quarter. Only scale the work that circles the tier: borders, swags, drops and ruffles. A top design or a set of accents does not get longer because the tier is wider. Hearts and other shapes have a longer edge than you might think, so measure around them rather than guessing.

Skill changes the clock

An advanced decorator pipes faster and cleaner than a beginner. Use the time for the person who will actually do it.

For a solo artist that means your own measured times. For a shop it means the decorator on the order: if a newer team member pipes the cake, the job takes longer, and either the price or your margin has to absorb that. Our post on pricing when you hire covers how to pay a team without losing margin.

Do not discount the second tier

A two tier Lambeth cake is not one cake and a bonus. The second tier needs its own piping, plus stacking and supports. Price every added tier at no less than you would charge to sell it alone.

A quick check: price the top tier as if it were a standalone cake, and the bottom tier the same way. The two tier price should be at least the sum of the two, plus stacking. If your quote comes out lower, something got discounted that should not have.

Common mistakes

Quoting from the serving chart and adding a flat "decoration fee"
Counting the visible elements but not the lines inside each one
Forgetting color changes on small details like dots and accents
Pricing a heart or shaped Lambeth like a round of the same width
Agreeing to "just a few more swags" after the quote without repricing

When a customer asks for changes, send an updated price with the change listed, for example "swags from 2 lines to 3, plus a second color on the drops". That keeps the conversation about the design rather than about your rate.
