In a large mixing bowl, stir together the flour, baking soda, baking powder, salt, and sugar until fully mixed.
In a second bowl, beat together buttermilk, eggs, and melted butter.
Add a little canola oil to your griddle or skillet, and spread it around with a paper towel to coat the whole surface of your pan. Bring to Medium heat.
Pour the buttermilk mixture into the flour mixture. Stir with a wooden spoon until it's just blended together.
Scoop the batter onto the griddle/skillet, using a 1/4 cup measuring cup for each pancake. (If adding berries or anything else into the pancakes, sprinkle on your berries immediately after you ladle the batter onto the griddle.)
Let cook until bubbles begin to appear on the surface, and then flip. Both sides should be cooked till golden brown.
