Combine yeast and 1/4 cup warm water in large bowl or strong mixer for 5 minutes until yeast is dissolved.

Add 3 cups of the combined flours and powder, 2 cups of warm water, melted vegan butter (I use organic Earth Balance), salt, and sugar. Make sure the butter is close to room temp and not hot before adding.

Mix by hand or with heavy-duty mixer for one minute then gradually add 3 - 3 1/2 cups of flour until moist (not sticky).

Knead or beat for 10 minutes until smooth, then transfer to an oiled bowl, flip, cover, and let rise in a warm place until doubled (about 2 hours).

Knead again and shape into two loaves. Place smooth surface up in loaf pans, cover and rise again in warm place until doubled (1 1/2 to 2 hours).

Preheat oven to 450, bake for 10 minutes, then reduce heat to 350, spritz with water and add any preferred seeds for a coated loaf, and bake for 30 minutes longer or until done.
