Bloom yeast: Stir warm milk with sugar and 1.75 tbsp honey in a bowl. Sprinkle in yeast and let foam 5–10 minutes.
Mix dough: Whisk in the melted butter and egg. Add salt and about half the flour; stir until shaggy.
Knead: Add remaining flour a bit at a time and knead until smooth and elastic, 6–8 minutes.
First rise: Place dough in a lightly greased bowl, cover, and let rise in a warm spot until doubled, 60–75 minutes.
Shape: Turn dough onto a floured surface. Roll to about 1/2 inch thick and cut into 16 even squares.
Second rise: Arrange on a parchment-lined sheet, spacing slightly. Cover and proof until puffy, 20–30 minutes.
Preheat oven to 350°F while the rolls finish proofing.
Bake: Bake the rolls until golden on top and set, about 12–15 minutes.
Finish: Brush hot rolls with melted butter and cool slightly before serving.
Make honey cinnamon butter: Beat softened butter, powdered sugar, 2 tbsp honey, cinnamon, and a pinch of salt until fluffy.
