Combine all of the ingredients except the butter in the bowl of a stand mixer.
Using a dough hook, mix on low speed for 1–2 minutes until the flour is absorbed.
Increase the speed to medium-high and mix for about 10 minutes until you have a soft, smooth dough.
Add the softened butter and mix for another 2–3 minutes until fully combined. The dough should look smooth and slightly shiny.
Cover and let rise for 1–2 hours until nearly doubled.
Divide the dough into 8 sections and shape into tight dough balls. Place onto a parchment-lined baking sheet.
Cover and let rise for about 1 hour.
Preheat the oven to 375°F.
Mix the egg wash ingredients together and brush over the tops of the rolls. Sprinkle with coarse sea salt.
Bake for 16–18 minutes or until golden brown.
Serve warm with honey butter.
Bread flour will give extra fluffy rolls but is not necessary.
