Ingredients
Method
Make the Coffee Custard Cream
- In a saucepan, mix half of the milk with sugar, cornflour, vanilla extract, and instant coffee powder. Stir until completely dissolved.
- Slowly pour in the remaining milk, stirring continuously to prevent lumps.
- Place the saucepan over medium-low heat and cook, whisking constantly. The mixture will slowly thicken in about 5-7 minutes.
- Once thick, transfer the custard to a bowl, cover it with cling film (touching the surface) to prevent skin from forming, and let it cool to room temperature.
- In a separate bowl, beat the chilled whipping cream and powdered sugar until it reaches a thick consistency.
- Mix the cooled coffee custard into the whipped cream until well combined. Refrigerate until needed.
Make the Coffee Topping
- Mix instant coffee powder with hot water, stirring well. Set aside.
- In a mixing bowl, whisk butter and powdered sugar until light and creamy.
- Whisk in the egg until fully incorporated.
- Pour in the coffee mixture and mix well.
- Sift in the flour, whisking until smooth.
- Spoon the coffee topping into a piping bag and set aside.
Make the Buns
- In a small bowl, combine ¼ cup of the warm milk, sugar, salt, and yeast. Let sit for 8-10 minutes until foamy.
- In a large bowl, mix flour, yeast mixture, and remaining milk until a shaggy dough forms.
- Add butter and knead for 10 minutes until the dough is soft and smooth.
- Place the dough in a bowl, cover, and let it rise for 2 hours or until doubled in size.
- Punch down the dough, divide it into 10 equal portions (56g each), and shape it into balls.
- Place buns on a lined baking tray, leaving space between them. Cover loosely and let them rise for 30 minutes.
Bake & Fill
- Preheat the oven to 180°C/350°F.
- Pipe the coffee topping in a spiral pattern over ⅔ of each bun.
- Bake for 16-18 minutes until golden brown.
- While still warm, make a small slit at the bottom of each bun and pipe in coffee custard cream.
- Stick a small piece of baking paper over the slit to prevent the filling from leaking out.
Notes
Notes:
- To prevent lump whisk cornstarch at room temperature/warm milk. And continuously whisk while cooking.
- To avoid deflation make the custard is cooled before mixing with cream.
- Don’t overwhip the topping for a smooth consistency.
- While piping avoid covering the entire bun so the dough can expand while baking.
- While activating yeast the milk should be warm, not hot.
- Don’t rush the rising process. Let the dough double in size before proceeding to the next step.
