approx. 3 tablespoons powdered sugar (optional, for topping)
Mix the oats and skim milk in a medium-sized bowl then set the bowl aside and allow to soak for 10 minutes. After ten minutes, add the egg, brown sugar, oil, grated orange rind and stir until well blended.
In a second medium-sized bowl, combine the all-purpose flour, the whole wheat flour, baking powder, baking soda and walnuts. Mix well and then fold the combined dry ingredients into the oatmeal mixture until just moistened. Do not over mix.
Gently fold in 1 cup frozen blueberries, reserving the extra half a cup of extra blueberries.
