Preheat griddle to 300 degrees. If using a stovetop, set the burner to medium-low.
In a large bowl, beat or whisk the dry ingredients together: flour, baking powder, baking soda, sugar and salt.
Stir in the wet ingredients: oil, egg and buttermilk.
Coat the griddle with nonstick cooking spray. Using a ladle or measuring cup, pour the batter onto the griddle. Place blueberries onto the top of each pancake. Once the batter bubbles on the surface, flip the pancake. Cook an additional 1-2 minutes on the second side before removing from griddle.
Notes
For the fluffiest pancakes, use an electric hand mixer to beat the batter.
