This is exactly how I made the bread. My machine has a whole grain setting and I set the baking control to medium - even though all the whole grain recipes in the cookbook that came with the bread machine said light. It came out perfect. I did not need to add extra water. The recipe came from a blog online, but I really don't want to name it for privacy reasons.
Oatmeal Whole Wheat Bread
Add the ingredients as they are printed into the bread machine pan.
1 cup old-fashioned oats
1 1/2 cups water (add more if dough is too dry in 1 tbs increments)
3 TBS butter
1/3 cup honey
2 TSP salt
1 1/2 cups white bread flour
1 1/2 cups whole wheat flour
2 1/2 TSP active dry yeast
Place all the ingredients in the pan, using the least amount of liquid and adding more if needed, as seen below.
Select Medium Crust and press start.
Observe the dough as it kneads. After 5 to 1- minutes, if it appears dry or stiff, or if the machine sounds like it's straining to knead it, add more liquid 1 TBS at a time until dough forms a smooth, soft, pliable ball that is slightly tacky to the touch.
After the baking cycle ends, remove bread from pan, place on cooling rack, and allow to cool 1 hour before slicing.
