UFO tart is a Kuching legend and honestly a great treat. But that fluffy meringue top fools people. Under it is a layer of buttercream and a sponge base, and buttercream is basically butter and sugar whipped together. So a small tart that feels airy is actually around 200 calories. Not a disaster, but not the freebie the size suggests.
The trap is they are small and cute so you grab two or three with your coffee. That is 400 to 600 calories of dessert sitting next to a sweet kopi. As a single treat with a kosong drink, totally fine bro.
