Preheat a lightly oiled griddle over medium heat.

In a large bowl, mix whole wheat flour, all-purpose flour, brown sugar, baking powder, buttermilk powder, and salt.

In a small bowl, mix oats and water. Whisk in eggs and olive oil. Pour into the flour mixture all at once. Continue mixing until smooth. Gently fold in blueberries.

Pour batter about 1/4 cup at a time onto the prepared griddle. Cook until bubbly. Flip, and continue cooking until lightly browned.
