*Pro Tips:

Buttermilk will make your buns soft, tender and tasty. But if you don’t have buttermilk on hand, don’t worry, the mixture of fresh milk and lemon juice may be a good substitute <¼ cup of milk with ½ tsp lemon juice will give a good result>.

Step By Step Directions

* Make the Buns:

- Sift the flour, sugar, and salt to a mixing bowl, mix well with a whisk then sprinkle the instant yeast over it, mix well again.

Note: I use instant yeast for this recipe, so it doesn’t require the yeast to be activated. If you don’t use the instant kind, remember to activate it before using.

- Make an indent in the middle of the flour, pour the milk and buttermilk into the bowl then lightly pour the beaten egg into it. Mix until well blended.

- Use an electric mixer or hand mixer to knead the dough at low speed for about 2-4 minutes until it turns to be smooth.

- Raise the speed to medium and continue kneading for about 10-12 minutes, the dough would be smooth and elastic; even you can stretch it out quite easily.

- Place 3tbsp softened unsalted butter into this step. Knead at low speed until all of the butter is incorporated then raise the speed to medium, continue kneading for about 5-7 minutes until it forms a very smooth and elastic dough

- Sprinkle some plain flour over the counter, transfer the dough onto it.

- Form the dough into a ball, tuck under the dough to make the surface smooth. If the dough is too sticky, simply use some flour to coat the hands.

- Put the dough in a big bowl greased with some oil, flip it over so that the dough can be covered by the thin layer of oil. Cover the bowl with a kitchen towel or plastic wrap and leave to proof for about 1 hour.

- Place the unsalted butter into a mixing bowl, beat at low speed for 1-2 minutes then sift sugar, salt and continue to beat until pale and creamy. Add the egg to the mixture, beat for about 30 seconds.

- Sift the flour and cocoa powder <additional> into a bowl then fold it by spatula until combined. Pour coffee into the mixture, mix well until we have the smooth batter like the

- Put the topping in the piping bag, chill it in the fridge.

*Pro Tips:

This requires chilling the topping to make the fine coffee layer because it contents a large about of butter and melt very fast in the oven.

* Prepare Fillings:

- Cut the butter into 12 cubes, and each cube is about 3-4g. Then put them in the freezer.

- After 1 hour, when the dough has already doubled in size, remove the kitchen towel/ plastic wrap and punch the dough down to release the air.

- Transfer the dough to a dusted cutting board. Lightly knead it again to relax the gluten in the dough and prepare it for the shaping state.

- Cut the dough into 10-12 equal pieces <each piece is about 42g>, then divide one of those pieces into 9-10 equal small pieces.

- Form each big dough into balls by tucking under each piece of dough. Cover and let all of them rest at room temperature for 5 minutes.

- Take the butter fillings out of the freezer. Flatten the small doughs and wrap the frozen unsalted butter fillings, set aside.

Note: The butter filling will melt rapidly while being baked, so this step will help the filling not to leak.

- Flatten big dough, insert the wrapped filling into the bun and wrap it up.

-Repeat with the remaining dough and fillings.

- Place the buns on to a lined baking sheet. Cover and let it rise for 30-40 minutes.

- Just before baking, pipe the topping onto the buns. Keep the bag straight up and start from the middle and pump out in circles around the bun.

- Place the buns in the oven and bake at 180 degree Celsius for about 15-18 minutes, the topping will melt and run down to cover the buns.

*Pro Tips:

The topping maybe turns dark so quickly, simply use the aluminum foil to cover the buns to prevent burning.

Storage

Store in airtight bag or container in 2 days.

The bun is more delicious when it is served hot, so simply warm up in the oven at 160 degree Celsius for 5 minutes to make Mexican coffee bun good again before serving
