40th Birthday Cake Flavours

Gluten-free and vegan options available. If you would like help choosing the perfect flavour combination, have a look at our popular cake flavours in London guide.

What Size 40th Birthday Cake Do You Need?

Choosing the right size ensures every guest enjoys a generous portion. For an elegant dinner party of 10 to 15 guests, a 7 inch round cake is a lovely choice. A celebration of 20 to 30 guests is perfectly served by a 9 inch cake. For larger parties of 40 to 60 guests, a two tier design or a 10 to 12 inch single tier provides plenty of slices. For a comprehensive overview including serving suggestions, read our cake portion guide.

Planning a grand 40th with 60+ guests? Paulina can design a spectacular three tier showpiece or pair a beautiful display cake with a separate cutting cake to ensure everyone is catered for.

Customisation Options

Every 40th birthday cake from Bake You Happy is completely bespoke. You have full control over the colour palette, the cake finish (discover the differences between buttercream and fondant), the flavour, and every decorative detail. Popular choices include edible gold leaf, hand painted elements, sugar flowers, personalised name plaques, acrylic or wooden toppers and metallic drips.

If you have seen a cake online that captures the mood you are looking for, share it with Paulina. She will use it as inspiration and craft a completely original design that is perfectly suited to the birthday person.
