Are there any lemmings who can recommend a good tres leches recipe? I’ve never had one, so I don’t really know what to look for.

I’ve had a look online and I’ve pretty much only been able to find recipes that have quantities in imperial measurements. For most things thats not a problem, but I have no idea how to covert solid metrics into volumetric and vice versa (eg. butter in TSP and flour in cups)

Closest I’ve been able to find is this one from a UK supermarket, but it looks as dense as a neutron star. My understanding is that these things are meant to be as moist as anything.

Can someone please share one that they’ve tried, liked and can vouch is authentic (also with metric measurements)
