Whisk together the flour, sugar, brown sugar, baking soda, and salt in a large bowl. Set aside.
1 1/2 cup all purpose flour, 2 tablespoons granulated sugar, 1 tablespoon brown sugar, 1 1/4 teaspoons baking soda, 1/4 tsp salt
In a medium bowl, whisk together buttermilk, butter, eggs, and vanilla extract. Whisk until well combined.
1 1/4 cup buttermilk, 4 tablespoons unsalted butter, 2 eggs, 1 teaspoon vanilla extract
Fold the wet ingredients into the dry ingredients until just combined.
Heat a large skillet over medium low heat. Spray lightly with cooking spray. (Or preheat a griddle to 375 degrees Fahrenheit).
Using a 1/4 cup measuring cup, scoop the batter onto the skillet. Cook until bubbles begin to form in the middle of the pancake and the edges of the pancake are starting to turn golden brown. Flip, and continue cooking until the pancake is golden brown, about three minutes on each side. Keep in mind that you may need to turn the heat down on a skillet over a gas flame after the first few minutes.
