Dissolve yeast in warm (not hot!) water until bubbly in bowl of stand mixer (about 5 minutes). Add sugar, salt, butter and more warm water and mix, using paddle attachment. Add 5 cups of flour slowly while mixer is on low speed until dough is mixed together. Slowly add remaining flour until dough is smooth. I ended up only adding 4 additional cups of flour (a total of 9 cups).

You can either divide dough in half and use the dough hook and stand mixer for each portion or you can knead the dough by hand. I chose to knead the dough by hand on a lightly floured surface. Knead dough (either method you choose) for 10 minutes.

Lightly spray large bowl with cooking spray (or butter). Place dough in bowl and flip over, so dough is covered with cooking spray. Cover dough and put in a warm spot to rise for an hour.

After an hour, punch down dough with your fist; divide dough in half; place on lightly floured surface. Roll out dough (one at a time) until each is about 12 x 12 square. Make sure the dough is of uniform thickness. Roll up each piece tightly; seal the edges well and tuck ends under the bread; set aside, seam side down. Repeat the process with other half of dough.

Lightly spray two 9 inch loaf pans (bottom and sides). Place bread dough into pans, seam side down. Cover pans, put them in a warm spot, and let dough rise for 1 hour, until doubled in size.

Place loaves on low rack in preheated 425 degree oven. Bake 15 minutes; then lightly cover each loaf with aluminum foil (so it won't get too brown); continue baking for an additional 15 minutes. (30 minutes total- half uncovered, half covered). As soon as bread is done, remove pans from oven, place on wire rack, and brush top of loaves with melted butter.

Once bread has cooled slightly, remove loaves from the bread pans. Slice and enjoy!
