Sure, Kopi Roti is technically a café, but we all know that we’re here for dem buns, son. The sweet crumbly coffee topping that hugs the round bun, which is warm and buttery on the inside—the kopi bun is a sensual experience.
That said, we admit that recipes like this can be intimidating for people who are new to baking, especially with using yeast. But with the instant yeast you find in grocery markets, there’s really nothing to be scared of, as long as you give the dough sufficient time to rise. Go play some Red Dead Redemption II while waiting (but don’t get too sucked into it; you have to get back to your dough!). As for the topping, you can use whatever kind of roast suits your taste, whether light, medium or dark. And for the butter, make sure it is nice and cold so that it’s a lot easier to handle.
