Preheat your oven to 425 degrees Fahrenheit. Spray a rimmed baking sheet generously with cooking spray. Set aside.
Whisk together the flour, sugar, brown sugar, baking soda, and salt in a large bowl. Set aside.
2 cups all purpose flour, 3 tablespoons granulated sugar, 1 tablespoon brown sugar, 1 1/2 teaspoons baking soda, 1/4 teaspoon table salt
In a medium bowl whisk together the buttermilk, butter, eggs, and vanilla extract. Whisk until well combined.
1 2/3 cups buttermilk, 4 tablespoons unsalted butter, 2 eggs, 2 teaspoons vanilla extract
Fold the wet ingredients into the dry ingredients until just combined.
Pour the batter into the prepared baking sheet and spread it into an even layer with a spatula. Add in your favorite toppings, such as chocolate chips, blueberries, strawberries, or bananas. Bake for 15 to 20 minutes or until the pancake is golden brown and a toothpick in the center comes out with just a few crumbs.
Cut into slices to serve and enjoy!
