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.
For the Mexican coffee bun recipe, I turned to my contributor Siew Loon. Check it out and hope you get to try this bun soon.

Thank you so much for the recipe, I have tried it yesterday and it’s perfect, it’s a big hit in my family and will be making again this afternoon, so excited because this is one of my favorite, the 1st time I ate this was in Malaysia near Petronas Tower years ago, the smell of a newly bake kopi roti is addicting and you want to eat it straight from the oven. I will be trying your other recipes.

Tried this recipe and my friends and sons love it. A friend said the taste is similar with the original coffee buns she had when she visited Malaysia. How to store the dough though. I plan to make the dough a day ahead before i need it. Thanks. Love this recipe.

Hi! My husband and I love coffee bun. he was the one who introduced it to me . He grew up eating it when he’s still leaving in Brunei and Singapore. We tried the Papparoti coffee bun and like it too. I’ve been baking coffee bun and I I’m following your recipe. got the taste of the coffee topping however it doesn’t stay and keeps falling off the bun. Any advice you can give?
Rasa Malaysia
Hi Regina, I am not sure maybe make sure they are attached better before baking.
Jessica
Made these today after falling in lust with them at a small coffee shop in Los Angeles (where they called them “mocha buns”). I followed the recipe as written, except added a dash of cinnamon and 1 tsp vanilla to the topping. Made each roll 75 gm size, which gave me 13 nicely sized buns. Fragrant, buttery, fluffy and delicious!

Awesome, so happy you tried out this Mexican coffee bun.
