In a large bowl, whisk together the sugar, flour, baking powder, baking soda and salt.
Add the buttermilk, eggs, and melted butter to the dry ingredients. Whisk just until combined. Don't over-mix.
Preheat a nonstick skillet over medium-low heat. Add a small amount of butter to the center of the skillet. The butter helps to create a golden-brown crust on the pancakes.
Scoop 1/3 cup of batter into the center of the pan, gently spread it out into a circle. (Batter will be thick) Place a few blueberries evenly on top. Cook until bubbles form on the surface and the edges begin to look set. Flip and cook another 1 to 2 minutes, until the pancakes are fluffy and fully cooked.
Serve pancakes warm with butter and maple syrup. Enjoy!
