Stir warm water with yeast and honey. Set aside to proof. Place butter into microwave safe bowl and cook on high until completely melted.
Pour milk and 1 egg into butter and stir together to incorporate. Pour into stand mixer. Yeast mixture should be foamy. Pour into stand mixer bowl. Sprinkle salt and 2 cups of flour overtop and knead until flour has been incorporated. With mixer on low, add in remaining flour.
Finished dough should be smooth, but still slightly sticky. Grease dough and bowl; cover and let rise 1 hour or until doubled in size. Punch down dough and form into 18 small dough balls the size of golf balls. Place on parchment paper lined or silicone baking mat covered baking sheet. Let dough rise another 30- 60 minutes.
In a small bowl, beat remaining egg with 2 tablespoons water. Brush tops of buns and sprinkle with sesame seeds. Bake at 350 degree for 12-15 minutes or until golden brown. Use as desired.
