How Much Cake Do I Need?

March 6, 2025

Your guide on how much cake you need

How much cake you need depends on the number of guests and the portion size which will then determine the size of cake you need. This can be different for Wedding cakes and Birthday or Celebration cakes.

Find out what the difference is and how to decide in this blog.

Serving Styles: Wedding Portions and Dessert Portions

What’s the difference?

There are two main types of serving styles: Wedding and Dessert portions, but which serving style should you go for? Find out what the difference is below:

Wedding portions (aka finger or elegant portions) are smaller, daintier servings, ideal for formal events and can be served in 1″ x 1″, 1″ x 2″ or even 2″ x 2″ dessert portions. If you’re offering your guests a dessert with your meal, couples usually opt for 1″ x 1″ or 1″ x 2″ slices.
Dessert portions (approx. 2″ x 2″) are more generous slices, typically rectangular or wedge-shaped, ideal for birthday or celebration events.

At The Flowering Baker, my cakes are available in different sizes and tiers, in vanilla or chocolate sponge, with options for a semi-naked or fully covered finish.

Which cake size do I need?

Once you know the number of guests you can decide whether you want dessert portions or wedding portions. Use my Cake Portion Guides below to help you choose the right cake size.

(Tip: It is always best to having more cake than not enough!)

All my cakes are round, 3 layers and approximately 5.5″ in height (it will be higher with the addition of buttercream flowers).

The final price will depend on your chosen flavour, sponge coverage, floral style and the level of design intricacy. You can be sure that your cake from The Flowering Baker is as unique and special as your celebration.

(Tip: For wedding cakes, I recommend a full covering of buttercream over a semi-naked covering to prevent the sponge from drying out if it is on display for a few hours, particularly in warmer weather.)

My cakes are best eaten on the day, any leftovers can keep for 2-3 days in an air tight container in the fridge. For more information on how to store your cake, visit my Cake Care Guide.
