It has been ages since my last post ;) Here is a recipe for delicious Mexican coffee buns (a.k.a. Rotiboy) I’d love to share!
These buns are a big hit in Malaysia and Singapore. Customers will patiently wait in line to savour the buns fresh from the oven! Bakery shops usually have such a great turnover, specially during lunch or rush hour that these buns are instantly gone within minutes after coming out from the oven!
Despite the tedious process to make these buns, it was well worth the effort ;) Hope you’ll enjoy them too.



Ingredients:
(A) Sweet Bun Dough
500 g (~ < 3cup) bread flour
20 g (~ 2 tbsp + 1 tsp) milk powder
75 g (~ 1/2 cup) icing sugar
6 g (< 1 tsp) salt 8 g (2 + 1/4 tsp) instant yeast 1 egg, lightly beaten 270 g water 60 g (~ 1/3 cup) butter, softened
(B) Coffee Topping
200 g butter, softened
160 g icing sugar, sifted
3 eggs, lightly beaten
2 tbsp instant coffee powder
1 tbsp warm water
Pinch of ground cinnamon
200 g (> 1 + 1/2 cup) all-purpose flour, sifted
(C) Filling
200 g unsalted butter, softened
1/2 tsp salt
1/2 tsp vanilla extract
70 g (1/3 cup + 1 tbsp) brown sugar
Directions:
(A)
1. Dissolve icing sugar in warm water (about 40 degrees Celsius). Add yeast and let stand for 10 minutes.
2. Meanwhile, combine bread flour, milk powder, and salt, in a mixing bowl.
3. Make a well at the centre of the flour mixture, gradually pour in the yeast mixture from (1), egg, and butter. Knead dough for about 10 minutes.
4. Shape dough into a ball. Place dough in a greased bowl covered with plastic wrap. Keep in a warm place, for about one hour, or until dough doubles its size.
(B)
1. Beat butter and icing sugar with electric hand mixer for about 5 minutes, on medium speed, until mixture is light and fluffy. Beat in eggs gradually.
2. Next, dissolve instant coffee powder in warm water. Pour the coffee into the mixture.
3. Sift flour into mixture and mix with electric hand mixer on low speed until it’s well combined. Refrigerate until ready to use.
(C)
1. Beat butter with an electric hand mixer for 3 minutes on medium speed. Blend in salt, vanilla extract, and brown sugar.
2. Refrigerate the filling until firm.
Finally……
1. Divide the bun dough into 12 portions. Roll each portion into a ball. Flatten the dough, insert filling from (C), and pinch the edges of dough together.
2. Let the dough rest for 30 minutes in warm place, until the size doubles.
3. When the dough is ready, scoop the topping mixture from (B) into a piping bag and pipe the topping in a spiral pattern onto the buns.
4. Bake them in a preheated oven at 400 F for 12-15 minutes, or until the buns are lightly brown.
5. Let the buns cool. These buns are best to serve warm! (*drooling*)
