How to Pick the Right Size Ice Cream Cake for Your Melbourne Celebration
Published on November 8, 2025
Planning a celebration? Whether it’s a birthday, family dinner, office surprise, or a cozy get-together, choosing the right size ice cream cake makes all the difference.
Too small → not enough slices.
Too big → melts before everyone gets to enjoy it.
At Ice Cream Cakes Melbourne, each of our cakes is handcrafted using Ben & Jerry’s ice cream — which means every serving is rich, satisfying, and indulgent.
So yes, slice size matters — but it’s simpler than you think.
Use this quick guide to get it just right.
How many people are You celebrating with?
Here’s the easy serving guide based on our cake sizes:
| Cake Size | Serves (Comfortably) | Best For |
|---|---|---|
| 6 inch | 6–8 people | Date nights, small family celebrations, intimate birthday moments |
| 8 inch | 12-14 people | Friend groups, small house gatherings, family dinner parties |
| 10 inch | 20–24 people | Bigger birthdays, workplace celebrations, backyard parties |
| 12 inch | 30–34 people | Engagements, milestone birthdays, large family celebrations |
Simple rule:
If dessert is the main event, go one size up.
If it’s just a sweet ending to a meal, the standard serving applies perfectly.
Ice Cream Cakes = Smaller Slices, same satisfaction
A slice of ice cream cake is richer and more flavour-packed than regular sponge cake.
Because Ben & Jerry’s flavours like:
-
Chocolate Fudge Brownie
-
Cookie Dough
-
Cherry Garcia
-
Salted Caramel Brownie
-
Phish Food
-
Netflix & Chill’d
…are dense, creamy, and full of chunks & swirls, guests naturally take smaller servings that still feel luxurious.
This means:
-
You serve more people per cake than with a sponge cake.
-
Leftovers (if any!) go straight to the freezer — no waste.
Which size gives the best Value?
If budget is a consideration, here’s what you should know:
-
Price per serving decreases as the cake size increases.
-
A slightly bigger cake = much better value per slice.
-
Ice cream cakes store beautifully — so leftovers are a bonus, not a problem.
Most popular value choice:
10 inch — big enough to share, affordable per person, and great for Melbourne gatherings where someone always asks for “just a tiny extra slice.”
