Instructions
Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper and gather your ingredients.
In the bowl of a stand mixer, combine the flour, yeast, sugar, and salt.
Add the warm water and mix on speed 1 for 1 minute.
In a small bowl, whisk together the eggs, yolk, and oil. Add this mixture to the mixer bowl.
Mix on speed 1 for 1 minute, then increase to speed 4 and mix for 8 minutes until the dough is smooth and elastic.
Remove the dough from the mixer. Divide into 16 equal pieces, about 108 grams each.
Shape each piece into a ball and place on the prepared baking sheet.
Cover with a clean, damp kitchen towel and let rest for 10 minutes. No longer or they will over proof and become dense and deflated.
Meanwhile, prepare the egg wash: whisk the yolk with 15 milliliters of water.
Brush evenly over each bun using a pastry brush, covering all sides, too. Sprinkle with sesame seeds if using.
Bake for 10–12 minutes at 425°F (220°C), until golden brown.
Transfer to a wire rack and cool before serving.
Keep buns in a zip-top bag or airtight container for up to 2 days at room temperature. For longer storage, freeze for up to 1 month. When ready to enjoy, let them thaw at room temperature, then refresh in a 350°F (177°C) oven for 3–5 minutes until lightly toasted.
