Preheat oven to 200 degrees F and a nonstick griddle to 350 degrees F. Lightly coat a griddle or nonstick skillet with nonstick spray.
In a large bowl, combine flour, oats, sugar, baking powder, baking soda and salt.
In a large glass measuring cup or another bowl, whisk together yogurt, milk, butter and eggs. Pour mixture over dry ingredients and stir using a rubber spatula just until moist. Add blueberries and gently toss to combine.
Working in batches, scoop 1/3 cup batter for each pancake and cook until bubbles appear on top and underside is nicely browned, about 2 minutes. Flip and cook pancakes on the other side, about 1-2 minutes longer; keep warm in oven.
