Order Your 18th Birthday CakeAn 18th birthday is the ultimate coming-of-age celebration — and it deserves a cake that's anything but ordinary. At Bake You Happy, Paulina designs every 18th birthday cake personally, working with you (or the birthday person's family) to create something that perfectly captures their personality, passions and style.
Whether they want something glamorous, edgy, sporty, arty or elegantly understated — we'll make it happen. Every cake is handcrafted from scratch using premium ingredients and delivered anywhere across London.
Popular choices for 18th birthday cakes include:
Gluten-free and vegan options available in all flavours. Not sure which flavour to pick? Our guide to popular cake flavours in London can help you decide.
Choosing the right cake size makes all the difference. For an intimate gathering of 10 to 15 guests, a 7 inch round cake provides generous portions. A party of 20 to 30 guests is perfectly served by a 9 inch cake, while larger celebrations of 40 to 60 guests call for a two tier design or a 10 to 12 inch single tier. For a detailed breakdown, take a look at our cake portion guide.
If you are planning a really big 18th with over 60 guests, Paulina can create a stunning multi tier showstopper or pair a smaller display cake with a larger cutting cake behind the scenes. Every option is tailored to your guest count and budget.
Every 18th birthday cake from Bake You Happy is fully bespoke. You can personalise everything from the colour palette and finish (whether you prefer buttercream or fondant) to the decorations, cake topper and message. Want edible printed photos, hand piped lettering, sugar flowers or metallic accents? Paulina can bring any vision to life.
You can also choose from extras like personalised name plaques, acrylic toppers, edible glitter, fresh flowers, macarons and meringue kisses. If you have seen a design on Instagram or Pinterest that you love, simply share the image and Paulina will create her own unique interpretation.
Complete the 18th birthday spread with coordinating cupcakes, cake pops, brownies or a dessert table. All designed to match your main cake and party theme.
