Ingredients:
2 cups warm water (110 degrees F/45 degrees C)
⅔ cup white sugar
1 1/2 tablespoons fast rise/instant yeast
1 ½ teaspoons salt
¼ cup butter, melted and cooled
6 cups bread flour
Directions:
Set up proofer or set oven to lowest temp with a slightly opened door (goal is 81°F).
Put all ingredients except for salt and butter into stand mixer. Using dough hook, mix on level 2 until dough forms.
Add cubed/cold butter and mix until the butter is fully integrated (this may take some time)
Add salt and continue mixing/kneading until salt is well integrated.
Place dough in well oiled bowl and rise in proofer/warm space for 1 hour, or until doubled in bulk.
Punch dough down and divide in half. Shape into loaves, and place into two well oiled 9x5 inch loaf pans. Allow to rise for 30 minutes in proofer, or until dough has risen 1 inch above pans.
