Very delicious
Lava Custard Mooncakes
Description
A lava custard mooncake is a modern Hong Kong-style mooncake with a soft, buttery skin and a molten salted-egg custard center that flows when you bite into it. Also called "flowing custard" or 流心奶黄, it is best enjoyed slightly warmed so the center turns silky and runny.
Pioneered and made famous by Mei Xin (Maxim's), lava custard has become one of the most sought-after mooncake styles for both gifting and personal indulgence. Yami stocks the authentic Hong Kong originals alongside creative takes — matcha, chocolate, purple sweet potato, and biluochun tea.

Maxim’s mooncakes 🥮, a long-standing Hong Kong brand, are incredibly delicious. Every year I try Maxim’s lava egg yolk, custard, and reduced sugar egg yolk lotus seed paste. They are delicious 😋!

The coffee is scorched and unpalatable. . . The chocolate is average, just the taste of brownie plus the chocolate sauce in the middle. It seems that I still want to buy milky custard. I love my purse.

Frequently Asked Questions
We answer everything you want to know about Lava Custard Mooncakes.
What is a lava custard mooncake?
It's a Hong Kong-style mooncake with a soft skin and a molten, flowing salted-egg custard center. Unlike traditional baked mooncakes, its filling is creamy and runny.
How do you eat lava custard mooncakes — warm or cold?
For the signature molten "lava" effect, warm them briefly (a few seconds in a microwave or a few minutes in an oven) so the custard center flows. They can also be enjoyed chilled for a firmer texture.
Is Mei Xin the same as Maxim's?
Yes. Mei Xin is the mooncake brand of Hong Kong Maxim's (美心), widely regarded as the original and most iconic maker of lava custard mooncakes.
Do lava custard mooncakes contain egg?
Yes, the custard filling contains salted egg yolk and egg, so they are not suitable for vegans or those with egg allergies.
How long do lava custard mooncakes keep?
Lava custard mooncakes have a shorter shelf life than traditional ones. Refer to the best-before date on the package and refrigerate after opening.
