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.

Recently an old friend of mine who has migrated to Australia started a small Malaysian bakery called Papparoti selling coffee-flavoured buns which happens to be one of my daughter’s favorite.

This has inspired me to revisit this Mexican coffee bun recipe and get to work.

The aroma of this Mexican coffee bun bun is really tantalizing and makes you just want to eat it piping hot.

Mexican Coffee Bun is a bun stuffed with butter and has a very crispy coffee pastry topping.

It is made popular by this Malaysian bakery called Rotiboy and now this bun is commonly known as “Rotiboy” in Malaysia and throughout Asia.

This coffee bun is also a very popular snack in Singapore, Indonesia, Thailand, and even Korea.

Mexican coffee bun is best eaten when it’s just off the oven and fresh.

The joy of baking this Mexican coffee bun or rotiboy is as fun as the joy of eating it hot and fresh.
