In a small saucepan, heat milk, butter and honey to 120°-130°F.
Add to dry ingredients; beat on medium speed 2 minutes.
Add pumpkin; beat on high 2 minutes. Stir in enough remaining flour to form a soft dough (dough will be sticky).
Turn dough onto a floured surface; knead until smooth and elastic, 6-8 minutes.
Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until doubled, about 1 hour.
Punch down dough. Turn onto a lightly floured surface; divide and shape into 24 balls.
Divide between 2 greased 9-in. cast-iron skillets or round baking pans. Cover with a kitchen towel and let rise in a warm place until doubled, about 45 minutes.
Preheat oven to 375°F.
Brush tops with beaten egg; sprinkle with seeds.
Bake until dark golden brown, 20-25 minutes. Cover loosely with foil during the last 5-7 minutes if needed to prevent over browning.
Remove from pan to a wire rack and serve warm. Inspired by a recipe from @tasteofhome.
