Whisk together flour, sugar, baking powder, baking soda and salt
Combine buttermilk, sour cream, vanilla, butter and eggs. Whisk lightly to break up eggs.
Make a well in the flour mixture and add in your egg mixture. Fold gently until combined but the batter is still lumpy. Let rest for 10 minutes.
Heat a skillet on medium heat for 5 minutes. Melt a Tbsp of butter in the pan and turn the heat down to med/low.
Scoop 1/4 cup pancake batter and pour into the middle of the pan. Let cook until you see bubbles popping in the center of the pancake and the edges of the pancake look dry and not shiny anymore. Then flip.
Cook your pancake for 1-2 minutes more then it's done! Top with powdered sugar, maple syrup and butter! Mmmmm!
