Warm the water and milk in the microwave for 20 seconds. Make sure it's warm to the touch.
Add the yeast, warmed water/milk, and whole wheat flour to the mixer bowl. Stir a little so that the whole wheat flour is immersed in the liquid. Set aside for 15 minutes so the mixture can bubble and rise a little.
Add the rest of the ingredients to the mixer. Mix the dough for 5-6 minutes. Add a tablespoon at a time of flour (either white or whole wheat) if the dough sticks to the side of the mixer bowl. Add a tablespoon at a time of water if the dough is a bit tough and the mixer struggles to mix.
While the mixer is mixing, grease the sides/bottom of the loaf pans.
After the mixer is done mixing, cut the dough in half and form 2 loaves. Place the loaves in the loaf pans and let rise in the microwave or oven (with the light on) for 60-90 minutes. The loaves just need to rise about 1 inch above the loaf pans.
Preheat the oven to 350°F about 10 minutes before the rising time is complete.
Bake for 30 minutes.
Flip the loaves out onto a baking rack and allow to cool completely before slicing and enjoying!
