Step 1

In a stand mixer bowl, dissolve yeast in warm water. Let stand 5 minutes, then stir in milk, oil, honey, egg, and salt until combined. Add 4 cups flour and mix on medium speed until a dough forms. Continue mixing until dough pulls away from sides, adding more flour if necessary.

Step 2

Turn dough onto a floured surface and gently knead until smooth and elastic. Place dough in a greased bowl, turning once to grease top. Let dough rise 1-1/2 hours or until doubled.

Step 3

Punch risen dough down and divide into 12 equal pieces. Shape each piece into a bun shape and place on parchment paper-lined baking sheets. (space buns about 4 in)

Step 4

Cover buns with plastic wrap and let rise 20 minutes or until puffy. Remove wrap and gently flatten each bun slightly. Cover buns with plastic wrap again and let rise an additional 30 minutes, or until doubled in size.

Step 5

Brush buns with beaten egg white and sprinkle with sesame seeds. Bake hamburger buns at 375F 18-20 minutes, or until golden-brown. Cool on a wire cooling rack.
