Coffee buns or better known as Mexican coffee buns, funnily enough, never originated in Mexico. Coffee buns, surprisingly, originated from a bakery in Penang, Malaysia, now internationally known as Roti Boy (other similar brands include: Roti O and Kopi Roti). No one knows why it’s specifically referred to as “Mexican” coffee buns but what we know is its massive popularity.

Originating from Malaysia, Roti Boy has become one of the most famous bakery brands in most of Southeast Asia, including Indonesia. I’m sure many people are quite familiar with this brand and this type of bread. It’s a bit similar to the Japanese melon pan but it’s very different in all terms of taste, texture and appearance. The owner of the Roti Boy company stated that in terms of taste, it’s hard to describe. It’s something that you need to try for yourself to find out.

For me, the original coffee buns from Roti Boy tastes, well, like coffee. It has a coffee taste but a salty aftertaste because of the salted butter in the centre of the buns.

The original coffee buns are made of a bun with a salted melted butter centre and topped off with a crunchy coffee on top. So once you take a bite, you’ll immediately get a sweet and crunchy exterior with a light and fluffy bun and a moist savoury centre.

The Best Coffee Buns Recipe

In this particular coffee buns recipe that I will be making, it’ll be a bit different. Instead of the outer layer being coffee flavoured, it’ll be milk flavoured and the bread bun itself will have a coffee flavour while the centre will still be filled with regular salted butter. And when fresh out of the oven, it’ll smell like coffee in the morning!

Making these coffee buns are quite simple as it has 2 components that you need to make: the bun itself and its outer crispy layer. The buns will be a classic soft bun but with some instant coffee powder as a little twist of change. And as for the outer layer, it’ll have a sweet milk flavour so it balances the bitterness of the coffee buns. I made the change of the flavours so that you will eventually experiment with other types of flavours yourself. One of the main reasons that I love baking so much is that you can create as many different varieties by playing around with flavours.

Eat It Hot and Fresh From the Oven

These coffee buns are better consumed fresh out of the oven whilst still warm because once it’s cooled down, the outer crunchy layer will turn soft and sticky. It’s better to bake this right before consumption which you can enjoy for breakfast along with a cup of coffee or as a snack throughout the day.

So without further ado, it’s time to bake these amazing coffee buns that I can’t wait for you guys to try!

Some tips that might be useful:

  • You can experiment with trying other flavours for the topping such as chocolate, matcha, etc. You should replace these ingredients in place of condensed milk for the topping or the instant coffee mix for the dough ingredients.
  • Be careful not to pipe too much of the batter out since it’ll be running down the bread itself.
  • You can pre-make the milk topping batter the day before in the fridge and use it on any day up to days for your bread. I don’t recommend it after 4 days since everyone’s fridge is different in terms of temperature as it might spoil.
  • Eat this while still warm and fresh, because as the bread cools, the topping will not be as crunchy as it is fresh from the oven.

Proceed to baking

  1. Preheat the oven to 180 Celsius.
  2. Take the topping mixture out of the fridge and pipe the mixture onto each dough. Pipe the mixture out by making a spiral starting from the top of the dough and slowly working your way down to the bottom of the dough. Stop piping once you’ve reached ¾ of the way from the bottom of the dough.
