Baked to golden perfection, this irresistible bun has won over taste buds across Asia, making it a must-try for any pastry lover.\n\nPrep Time: 10 minutes minutes\n\nCook Time: 1 hour hour 3 minutes minutes\n\nTotal Time: 1 hour hour 13 minutes minutes\n\nServings: 10\n\n### Ingredients US Customary Metric 1x 2x 3x\n#### For the Bun:\n- ▢\n  17 oz bread flour\n- ▢\n  3 oz castor sugar\n- ▢\n  1 teaspoon salt\n- ▢\n  1 oz baking milk powder, optional\n- ▢\n  0\\.35 oz dry yeast\n- ▢\n  1⅓ cups water\n- ▢\n  1 large egg\n- ▢\n  2 oz unsalted butter\n\n#### Topping:\n- ▢\n  7 oz unsalted butter\n- ▢\n  5 oz powdered sugar, sieved\n- ▢\n  3 large eggs, lightly beaten\n- ▢\n  7 oz cake flour\n- ▢\n  1 tablespoon instant coffee,  + 2 tablespoons hot water or 3 tablespoons Espresso\n- ▢\n  1 tablespoon coffee liquor,  or 1 tablespoon coffee essence, optional\n\n#### Filling:\n- ▢\n  3\\.5 oz unsalted butter\n\nCook Mode\n\nPrevent your screen from going dark\n\n### Instructions\n#### For the Bun:\n- Add all the dry ingredients and mix thoroughly. Gradually incorporate the water and egg mixture while kneading on medium speed with a dough hook for about 10 minutes. Slowly add the butter and continue kneading until the dough is shiny and elastic. (Note: The dough should stretch without breaking.)\n- Cover the dough with a cloth and let it proof for about 40 minutes, or until it has doubled in size. While the dough is proofing, prepare the topping.\n\n#### Mexican Coffee Bun Topping:\n- Beat the butter and sugar until pale in color. Gradually add the egg, mixing well. Fold in the flour on low speed, then add the coffee mixture and liquor. Mix until combined and set aside.\n\n#### To Make Bun:\n- Remove the dough and, on a lightly floured surface, punch it down to release the air. Divide the dough into 45 g (1.5 oz.) portions. Roll each portion into a small circle and place 1 teaspoon of butter in the center. Wrap the dough around the butter and shape it into a bun.\n- Leave the prepared buns to proof for about 45 minutes, or until doubled in size. Place the cream topping in a piping bag and pipe it in circles around each bun.\n- Bake at 215°C (419°F) for 18 minutes.\n\n### Notes\n- **Chill the butter filling** beforehand so it stays firm and creates a rich center when baked.\n- **Use just a teaspoon of butter** for filling to prevent it from leaking while baking.\n- **Pipe the topping just before baking** to make sure it spreads nicely and doesn’t melt too early.\n- **Check the buns after 15 minutes** and cover them with foil if they’re browning too fast.\n\n### Nutrition\nServing: 10g, Calories: 638kcal, Carbohydrates: 75g, Protein: 12g, Fat: 32g, Saturated Fat: 19g, Polyunsaturated Fat: 2g, Monounsaturated Fat: 8g, Trans Fat: 1g, Cholesterol: 144mg, Sodium: 276mg, Potassium: 170mg, Fiber: 2g, Sugar: 24g, Vitamin A: 1008IU, Vitamin C: 0\\.2mg, Calcium: 57mg, Iron: 1mg\n\nNutrition information is automatically calculated, so should only be used as an approximation.\n\nPlease rate and comment below\\!\n\nShare:\n\n[Pin](https:\/\/pinterest.com\/pin\/create\/button\/?url=https:\/\/rasamalaysia.com\/mexican-coffee-bun-rotiboy\/&media=https:\/\/rasamalaysia.com\/wp-content\/uploads\/2024\/10\/mexican-coffee-buns2.jpg&description=Mexican%20Coffee%20Bun \"Share on Pinterest\")\n\n[Facebook](https:\/\/www.facebook.com\/sharer\/sharer.php?u=https:\/\/rasamalaysia.com\/mexican-coffee-bun-rotiboy\/&display=popup&ref=plugin&src=share_button \"Share on Facebook\")\n\n[Tweet](https:\/\/twitter.com\/share?url=https:\/\/rasamalaysia.com\/mexican-coffee-bun-rotiboy\/&text=Mexican%20Coffee%20Bun \"Share on Twitter\")\n\n[Email](mailto:?subject=Your%20friend%20has%20shared%20an%20article%20with%20you.&body=Mexican%20Coffee%20Bun%0D%0Ahttps%3A%2F%2Frasamalaysia.com%2Fmexican-coffee-bun-rotiboy%2F%0D%0A \"Share via Email\")\n\n[![](https:\/\/rasamalaysia.com\/wp-content\/uploads\/2022\/06\/website-author-profile-2018n.jpg)](https:\/\/rasamalaysia.com\/about\/)\n\nAbout Bee Yinn Low\n\nBee is a recipe developer and best-selling cookbook author, sharing easy, quick, and delicious Asian and American recipes since 2006.
