Birthday cakes for adults

Pink ombre birthday cake with fresh roses

Birthdays deserve to be celebrated in style, and nothing makes a statement quite like a bespoke birthday cake crafted especially for the occasion. At La Petite Bouche Bakery, we create unforgettable cakes that bring a little decadence to your celebration and make special days even more memorable.

Our adult birthday cakes are always bespoke, meaning the size, shape, flavour, decorations - and more! - are tailored to your requirements. This includes accommodating dietary restrictions too; our cakes are plant based by default (egg and dairy free) and we have options free from other allergens too. The result? A delicious, one-of-a-kind showstopper that everyone can enjoy.

A cake as unique as you

Unlike some bakeries, we don't have a catalogue of cakes that you're required to choose from. Instead, when you make an enquiry we'll take our time to understand what you need and give you the freedom to choose a design that ticks all the boxes. If you're drawing a blank when it comes to ideas then don't worry - we are happy to get creative and suggest some options for you.

Making milestones memorable

Milestone birthdays call for extraordinary cakes. Whether it's an 18th, 21st, 30th, 40th or beyond, we can create a cake that makes a statement and becomes the talking point of your celebration. Some popular options for milestone birthdays include:

  • Photo cakes featuring treasured memories

  • Number cakes shaped as the age being celebrated

  • Themed cakes reflecting the recipient's passions or hobbies

  • Multi-tier, statement cakes for larger gatherings.

  • Lemon drizzle

  • Biscoff

  • Double chocolate

  • Cookies and cream.

Sizes, servings and prices

Rabbit cake topper

In terms of size, we can guide you to help you arrive at that 'Goldilocks' sweet spot - enough cake for everyone to treat themselves to a hearty slice (or two!), but not so much that you end up with wastage.

Our most common adult birthday cake sizes and the number of people they feed are listed below. These figures are for round cakes in our standard height - four layers of sponge, six inches tall - and are based on a 2"x1"x6" portion size, called a dessert portion. A dessert portion is about the same amount of cake as two cupcakes. If you are serving other food at your celebration or prefer smaller portions, then cutting the cake into 1"x1"x6" slices will suit better - this will yield double the number of portions listed below.

Safari cake

Since no two cakes adult birthday cakes we create are the same, it's impossible for us to have a published price list. Instead, we have a base price for a standard, plainly-iced cake and will then give a quote for your tailored cake once we've got all the details. This will depend largely on the complexity of the design and how long it takes to make your cake. We are always happy to advise on adjustments to your ideas to bring them in line with your budget, if you have one. Full payment is required two weeks before delivery.
