I have long heard about the legendary Mexican coffee bun or Rotiboy, a made-in-Malaysia bun with a crusty coffee topping and butter filling.
The word “Mexican” might be misleading but this bun originated from a bakery in Bukit Mertajam, Penang, and now Mexican coffee bun is famous all over Asia, with many bakeries and copycat bakeries selling this popular Mexican coffee bun.
I finally had a chance to taste this aromatic and wonderful bun when I was home in Penang earlier this year.

I tried the recipe twice, both times my dough turned out rather sticky so I added about 15% more dough. Not sure if my measurements were off to begin with, but the end product was still delicious!
Thank you for this!

Hi RM,
Do I need to melt the butter for the dough? Or just softened in room temp?
And I can use salted butter or must be unsalted butter? Thanks!

No.

Jus wondering can i use this recipe using breadmaker?
Rotiboy is the Mexican Conchas with a different topping, they write this in their web page… “the one and only “rotiboybun”, which has since become the generic name of the Mexican bun recipe it was based on”. I try Rotiboy in Jakarta and love it! I’m glad I found your page by accident as I was looking for the recipe for a very long time. Thank you for sharing.
