We had our baby's 100-day party not long ago, but since our little treasure only made it to 100 days thanks to our nanny, we decided to throw a second 100-day party for her too. While looking into Jamsil lettering cakes, I found Circus Rabbit in the Jangmi Complex and reached out right away.

There aren't many custom lettering cake shops near Jamsil, but this one is close to both Jamsil Station and Olympic Park, so it seems like a great spot to order a custom cake for any special occasion.

Storage notice for the dairy whipped cream cake

This Songpa lettering cake shop, Circus Rabbit, uses dairy whipped cream, so it can melt easily! It tastes better for it, but you'll want to follow the storage notes above, right?

Picking up the 100% dairy cream 100-day cake

I arrived right at pickup time, and our baby's pretty 100-day cake was already waiting. In the showcase there was this cake that looked so white and pure, my heart skipped a beat.

The owner of Circus Rabbit did the icing like it was true art. It's a white whipped-cream cake, but the lettering is clean with no excess, so pure white — it was absolutely perfect as a Jamsil 100-day cake!

An owner trained at a top Japanese pastry school

This Jamsil lettering cake looked so delicious and had such good reviews that I wondered why — turns out the owner trained at a famous Japanese pastry school haha. So I took a big bite of cream, and it really did melt away in my mouth.

100% dairy whipped cream is hard to work with, but at Circus Rabbit, the Jamsil lettering cake shop, you can really taste a deliciously clean icing job.

The pure white cake I had in mind! If you're deciding on a Jamsil 100-day cake, this kind of design from Circus Rabbit is worth considering.

You can also order figure cakes for kids and kindergarten birthday cakes, so take a look! I'm planning to trust Circus Rabbit with our next birthday cake too haha. I bet our baby will love a figure cake when she has her kindergarten birthday party someday!

The 100-day cake packaging was finished like this, and they even tied a blue ribbon on top, so it felt totally like a birthday present.

When I got home and unwrapped it, the pure white 100-day cake looked even more striking.

Shot from a distance, it almost looked like a traditional 100-day rice cake! haha

I agonized a lot over what design to choose for the 100-day cake from this Jamsil lettering cake shop, but the owner showed me tons of design samples. There were even more photos beyond what I saw, but I went with the design the owner recommended haha.

Ta-da! Even prettier with these lovely candles stuck in, right? haha Tying ribbons onto the candles added a whole extra spoonful of sentiment 💕

Together with our baby and her nanny, we stuck the candles into the custom-ordered lettering cake and celebrated the 100 days. It felt meaningful, since it's thanks to our nanny that we could raise her well to this point.

Isn't it just so pretty? ㅠㅠ For a simple design like this lettering cake, the icing really matters, and I think the owner of Circus Rabbit nailed it with such a clean finish.

How did the Circus Rabbit lettering cake taste?

Once I tasted it, I understood why the owner's famous Japanese pastry school background mattered. The cake melted away in my mouth, and both our nanny and my husband kept praising how truly delicious it was.

Looking at it this way, it's even prettier, right? haha The lettering part is chocolate!

I cut into it myself and tried a piece — the flavor of the 100% dairy whipped cream was seriously next-level. Usually when you order a lettering cake, even if reviews say it's tasty, it often turns out dry, but this Jamsil lettering cake from Circus Rabbit would be delicious enough to sell as just a plain cake.

When you want a pure milky cake, this is worth ordering even without lettering — the sponge is springy and fluffy, and the cream is so good. The designs are varied too, so if you have an occasion in Jamsil, book a restaurant near Lotte Mall and order a custom cake from Circus Rabbit — it'd be perfect. It's also super close to Jamsil Lotte World Mall!

Getting to celebrate our baby's 100 days with such a pretty and delicious cake was truly the best! If you're a Jamsil mom looking for a 100-day cake, I definitely recommend getting a lettering cake from Circus Rabbit 💕
