Activate the Yeast: Combine warm water, yeast, and sugar in your stand mixer bowl. Whisk everything together and let it sit for 5 minutes. You should see bubbles forming on top, indicating the yeast is alive and ready to work.

Mix the Dough: Add melted butter and salt to the yeast mixture. Whisk to combine everything smoothly. Slowly add flour one cup at a time. Let your mixer knead the dough for 3-4 minutes using the dough hook. The dough will look slightly shaggy at this point, which is normal.

First Rise: Turn the dough onto a clean surface and knead by hand for 1-2 minutes until smooth. Place it in an oiled bowl, cover with plastic wrap, and let it rise for one hour until doubled in size.

Shape the Loaves: Preheat your oven to 375°F. Spray two 9x4 inch loaf pans with cooking spray. Divide the dough into two equal pieces. Press each piece into a rectangle about 9 inches wide. Roll it up tightly like a jelly roll and place seam-side down in the prepared pans.

Second Rise: Cover the loaves with a clean kitchen towel. Let them rise for 45-60 minutes until the dough crests about half an inch above the pan rim.

Bake to Perfection: Bake for 25-30 minutes, rotating the pans halfway through for even browning. The loaves should be golden brown on top and sound hollow when tapped. Cool in pans for 5 minutes, then turn out onto wire racks to cool completely before slicing.
