When I visited my mother during school breaks, she'd often buy a cake from a Mexican supermarket. A tres leches cake that was mocha flavored.

It's oddly specific, but it tastes like heaven- especially when paired with milk! The flavor is sweet despite the bitterness of coffee. The frosting was light and the drizzle of caramel on top was perfect. I'd seriously do some insane things to get my hands on the recipe for it.
It's a bit nostalgic. Years ago was when I last had it, and I've never seen a similar cake since. The supermarket is hours away from where I live; and I doubt I'll ever talk to my mother again.
