Homemade “Rotiboy” Mexican Coffee Bun

Homemade

There’s a popular bake shop that started in Malaysia called “Rotiboy“. Their signature product is the Rotiboy bun which is a sweet Mexican butter bun baked with a crisp, coffee-flavored topping. Rotiboy got so popular that they were able to aggressively expand throughout Asia. Many copycats also popped up, but the original Rotiboy is the best.

Hooked on Rotiboy

The last time we were in Malaysia, the cousins brought over a few Rotiboy buns for us to try. I took one bite, and was hooked! I loved how the sweetness of the bun balanced against the saltiness in the butter and the slight bitterness of the coffee.

I quickly gobbled my bun up. Unfortunately, there weren’t many Rotiboy buns to go around so I was left craving for more. The Rotiboy slogan says it all: “One is never enough!

Annie wanted to learn how to make a Rotiboy bun at home and came upon a few recipes. This one comes close.

“Rotiboy” Mexican Coffee Bun Recipe

(makes about 17 buns)

Coffee Topping Ingredients

200 g softened butter
160 g icing sugar
3 lightly beaten eggs
2 tbsp instant coffee dissolved in 1 tbsp water
a pinch of ground cinnamon
200 g flour

Method

Beat the butter and sugar until the mixture is light and fluffy. Gradually beat in eggs. Mix in coffee flavoring. Sift flour onto mixture and mix until combined. Refrigerate the mixture.

Sweet Bun Dough Ingredients

500 g bread flour
20 g milk powder
75 g castor sugar
6 g salt
8 g instant yeast
5 g bread improver (vital wheat gluten – optional)
1 lightly beaten egg
270 g water
60 g softened butter

Method

1. Mix flour, milk powder, sugar and salt in mixer on low speed 1 min.

2. Add in yeast, egg and water. Mix on low speed for 1 minute, then medium speed for 8 minutes.

3. Add butter and mix for 5 minutes more on medium speed until a soft, smooth and elastic dough forms.

4. Remove dough from mixing bowl and shape into a ball.

5. Divide the dough into 55 gram portions. Roll each portion in to a ball and then cover and set aside for 10 minutes.

6. Flatten a ball of dough and place a 10 gram cube of butter into the center of the dough.

7. Gather the edges and pinch to seal. Pat into shape and place on a greased baking tray. Proof the buns for 45 minutes.

8. Preheat oven to 200*C (400*F).

(Notice that we’re using the wrappers from sticks of butter to line the baking sheet. Annie learned this tip from Fine Cooking magazine. The butter wrappers are like pre-greased parchment paper!)

9. Scoop the topping mixture into a piping bag and pipe the topping in a spiral pattern onto the buns.

10. Bake for 12-15 minutes or until the buns are lightly brown.

Remove from oven to cool, but not too long. They are best eaten warm. Can’t eat just one!

    >I love that you posted the recipe for this, Nate. I’m all over it. I swear I’m gonna bake someday. Maybe even soon.

  2. Chawanmushi says:

    >Hi Annie
    Wow …I learn something new here.
    Didn’t know that butter wrappers could be used this way. Thanks for sharing this. Love those rotiboys by the way :-)

  3. Rajee, irving, tx says:

    >what is bread softer and bread improver in this recipe?

  4. Nate-n-Annie says:

    >@rajee – the closest thing you can find is “vital wheat gluten”. But it’s not necessary in this recipe…optional only.

  5. Mela says:

    >Wow! Is this the kind served in KLCC Suria? Oh man! It looks the same! Must try!

  6. Nate-n-Annie says:

    >@Mela – it’s a very close copy. Very delicious!

  7. Lydia (The Perfect Pantry) says:

    >Oh, I can see how those would be addictive! I’ll have to look for Rotiboy next time I’m lucky enough to get to that part of the world.

  8. pigpigscorner says:

    >ooo I love these! Thanks for posting this recipe, will definitely give this a try!!

  9. Rowena says:

    >Oh java joy! One of these with a cappuccino in the morning and I’ll be spinning in circles. Wheeeeeee!

    Great post!

  10. Carolyn Jung says:

    >I’ve never heard of these things. When I saw the word, “Roti,” I thought of the flaky Malaysian flatbread served with curry sauce. Obviously, this is a different type of roti. The coffee flavor sounds absolutely divine.

  11. Woman says:

    >Hi Nate,

    I love that you posted this recipe, I’ve been searching for Rotiboy’s recipe and I will try this one at home. However, the problem I have is I live in Chicago and now during winter the temp drops below 70s. How to proof bread and make sure the yeast is working?
    thanks in advanced.

  12. Joie de vivre says:

    >Those look beyond amazing!

  13. _ts of [eatingclub] vancouver says:

    >Oooh, I don’t really go for sweet things but this attractedme right away! And yeah, great idea re the butter wrappers!

  14. ICook4Fun says:

    >I love Rotiboy bread too. Been eating it since I came back. Thanks for sharing the recipe as will try it out when I am back to US.

  15. Jenster says:

    >Would you mind posting a cross-section of the bun? From the outside, it looks amazingly good.

    Although, thanks for sharing the tip on using butter wrappers to line your baking sheets. I’ll have to start doing that. And to think that all this time I’ve been throwing away the wrappers and then getting out the parchment!

  16. Nirvana says:

    >This looks FANTASTIC!

  17. Manger La Ville says:

    >Wow Rotiboy sounds amazing and looks delicious. I think we should name your blog the master of sweet buns. Butter wrappers is a great idea.

  18. Food For Tots says:

    >It reminds me of those days when rotiboy was a hit in KL. The smell of the freshly baked bun was so irresistable when I passed by the shop. Your version looks exactly like what I ate before. If u open a bakery shop in future, I will be ur 1st customer. Hehehe!

  19. Carrie says:

    >I’ve never heard of this beauty before. Thanks for sharing something so unique. Looks like it tastes amazing, too.

  20. Jo says:

    >Even though this has been around for a while now, I still love this bread warm from the oven. I remember when it first came out in Malaysia and Singapore, people would Q for at least 1/2 hour just for this.

  21. Nate-n-Annie says:

    >@Lydia – why wait? Try this recipe out at home!

    @pigpigscorner – do let us know how it turns out for you!

    @Carolyn – “roti” just means bread. “Rotiboy” is a chain of bakeshoppes, so they do a lot of breads, cakes, etc.

    @Woman – You could try proofing them in the oven with the light on or with a little pan of warm water to raise the temp a bit.

    @ICook4Fun – I envy you that you get to have the real thing!

    @Jenster – unfortunately, I don’t have a pic of the inside. I eat the things too quickly to stop and get a shot!

    Re: the butter wrappers. The only hard part is keeping all the butter wrappers organized in your fridge while you save up enough to cover a sheet pan.

    @Manger La Ville – thanks!

    @Food For Tots – thank you, you’re too kind.

    @Jo – I realize the fad has gone but that doesn’t take away from how tasty these buns are.

  22. Maggie says:

    >These look so good! It’s nice to see coffee in a baked good that isn’t overwhelmed with chocolate.

  23. Starningblue says:

    >Hi there, your Rotiboy buns look great! Cant buy these in Singapore or Msia anymore.. only way is to DIY :)

    Cheers,
    Starningblue

    >@dessertobsessed – We do have a culinary converter widget on the bottom of our right sidebar…but you really should get a digital scale.
