Homemade Hawaiian Buns

Beat eggs in a bowl. Add pineapple juice, sugar, 1/2 cup butter, and vanilla extract.

Measure 3 cups of flour into a large bowl and stir in egg mixture with a wooden spoon until well combined. Sprinkle in yeast packages one at a time, mixing well. Add 3 more cups flour and mix well, using your hands if needed. Make sure all flour is well incorporated; the dough should be tacky to the touch, but not overly sticky. If dough is too wet, mix in a little extra flour, 1 tablespoon at a time.

Cover dough with a clean towel and set in a warm place to rise for 1 hour.

Remove dough from the bowl and knead in remaining 1/2 cup flour, approximately 10 to 15 times, making sure flour is well incorporated. Form dough into rolls and place on buttered pans. Cover and place in a warm area to rise until doubled in size, about 1 hour.

Preheat the oven to 350 degrees F (175 degrees C).

Bake in the preheated oven until tops are golden brown, 25 to 30 minutes. Brush tops with remaining 1/4 cup melted butter.
