How Much Does a Custom Birthday Cake Cost in Singapore?
Updated October 2026
Short answer: At Happy Cake, birthday cakes start from $39.90 for a 5-inch Create Your Own Ombre cake (feeds 4–6). Most families spend $65–$100 on a 7- or 9-inch cake that feeds 8–20 people. Island-wide delivery is $15, or free for orders of $180 and above.
The final price depends on three things: the size you need, the style of cake, and how and when you want it delivered.

1. Size: how many people are you feeding?
Size is the biggest driver of price. As a rough guide for our standard cakes (about 2.7" tall):
- 5 inch: 4–6 people, good for a small family celebration
- 7 inch: 8–10 people
- 9 inch: 14–20 people, the usual choice for a kids' party
- 11 inch: 25–35 people, for school or office celebrations
Our Signature Ombre cakes are taller (about 4"), so the same diameter feeds more people. A 7-inch tall ombre serves 15–20. See the full Cake Size Guide.
2. Style: simple, photo, or fully custom?
- Ready designs (All Time Favourites, Korean-Style) are the most affordable way to get a beautiful cake.
- Photo cakes add an edible printed image, such as your child's photo or a favourite theme, from $62.90 for 7 inches.
- Create Your Own Ombre lets you choose your colour blend from $39.90, which makes it the best value for a personalised look.
- Fully customised designs are quoted individually based on the design. WhatsApp us a photo or idea for a quote, and please allow 5–7 days. See our Customised Cakes page.
3. Delivery and timing
- Island-wide delivery: $15, or free from $180
- Specific 1-hour delivery slot: $40
- Lead time: at least 3 days for most cakes, 5–7 days for customised cakes
- Same-day: may be possible if you order before 11am, for selected cakes. Please WhatsApp us to confirm before paying.
Sample budgets
- Small family birthday (5 people): 5" ombre cake $39.90 + delivery $15 = $54.90
- Kids' party (15 children): 9" photo cake $87.90 + delivery $15 = $102.90
- Office celebration (30 people): 11" Strawberry Blush $135.90 + 5" cake for a second flavour $46.90 = $182.80, with free delivery
Can I keep costs down?
Yes. Order at least 3 days ahead to avoid rush requests, choose a ready design over a fully custom one, and if you're close to $180, add Minibites or candles and toppers to unlock free delivery.
