Here's the recipe - slightly altered - originally from Robyn Cardon from My Pink Stamper.
3 1/2 cups very warm water
1 1/2 Tbsp. yeast
1 Tbsp. white sugar
Mix together in a large mixer and let sit for 8 minutes.
2 1/2 cups white bread flour
2 cups wheat flour
2 tsp. salt
1/4 cup oil
3/4 cups white sugar or honey
Mix well and then slowly add 5-6 cups of wheat flour until dough starts pulling away
from the sides of your mixing bowl; knead for 8 minutes.
While that's kneading, grease 3 large loaf pans with cooking spray & preheat your oven to 170 degrees.
Divide dough into three loaves and press down into pans.
Place pans in 170 degree oven for 10 minutes then turn the oven off. Let sit in warm oven until doubled in size. Then, turn oven on to 350 degrees and bake for about 30 minutes.
