In a large bowl, whisk together dry ingredients: whole wheat pastry flour through salt.
In a separate medium bowl, whisk together wet ingredients: milk through egg. Note: mixture will be slightly lumpy and that's ok!
Slowly pour the liquid mixture into the dry mixture and stir until ingredients are just incorporated, being careful not to over mix.
Gently fold in blueberries.
Pour batter on a pre-heated griddle, about 1/4-1/3 cup at a time. When bubbles start to form, it's time to flip. Continue cooking on the second side until golden brown. Repeat until all batter is gone.
