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 made some today but forgot to put in the butter in my dough. Will have to remember to put butter in my next round.
Lyisa
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.

Hi Lyisa, all my recipes are good please try more!

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
Thanks for your recipe.
I have tried many times unfortunately I can never get the crusty top. It always turns out game-like texture.
Can you please advise.
Rasa Malaysia
What is game-like texture?
Jase
Good day!
I followed the recipe but I ended up getting a gloppy gooey dough. I was kneading it with the KitchenAid’s dough hook for 20 minutes (speed 2) already but it didn’t become elastic.
Should I knead it longer?
Ida
Super yummy

Thanks!

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