Order Your 21st Birthday CakeA 21st birthday is one of life's most celebrated milestones — the key to adulthood, the champagne toast, the unforgettable party. At Bake You Happy, we create 21st birthday cakes that rise to the occasion. Paulina designs each cake personally, working with you to capture the birthday person's personality and celebration style.
From show-stopping gold drip cakes to sophisticated champagne-themed tiers, every 21st birthday cake is handcrafted in our Chingford studio and delivered anywhere across London.
Turning 21? Now you can have the grown-up flavours too:
Non-alcoholic, gluten-free and vegan options available in all flavours. If you are still deciding, our guide to popular cake flavours in London is a great place to start.
Getting the right size is important so every guest gets a generous slice. For a smaller gathering of 10 to 15 guests, a 7 inch round cake works perfectly. Parties of 20 to 30 guests are well served by a 9 inch cake, while larger celebrations with 40 to 60 guests will need a two tier design or a 10 to 12 inch single tier. For more detailed guidance including portion diagrams, see our cake portion guide.
If you are hosting a truly grand 21st with 80+ guests, Paulina can design a spectacular three tier creation or pair a showpiece cake with a separate cutting cake. She will help you find the perfect solution for your guest count and budget.
Every 21st birthday cake is designed from scratch. You choose everything: the colour scheme, the finish (learn more about buttercream vs fondant finishes), the decorations, and the personal touches that make it uniquely theirs. Popular customisation choices include edible photo prints, hand painted details, fresh or sugar flowers, metallic leaf, personalised name plaques and acrylic toppers.
Have a Pinterest board or Instagram save folder full of inspiration? Share it with Paulina and she will craft her own original interpretation, bringing together your favourite elements into one stunning design.
Pair your 21st birthday cake with matching cupcakes, cake pops, personalised biscuits or a full dessert table. Everything coordinated to your party theme and colours.
The ordering process is relaxed and personal. Simply message Paulina on WhatsApp or email with your party date, approximate guest count, favourite flavours and any design ideas. She will send you a personalised quote and work with you to refine every detail until it is perfect. A £50 deposit secures your date, with the remaining balance due before delivery.
