Silver Dollar Pancakes

Blend sour cream, flour, eggs, sugar, salt, and baking soda together with a whisk until smooth.

Heat a skillet or griddle over medium-high heat. Lightly coat with butter. Drop batter 2 tablespoons at a time onto griddle, leaving plenty of space for spreading. Fry until bubbles form and break on the pancake's surface and bottoms are browned, 3 to 4 minutes. Flip and cook until until browned on the other side, 1 to 2 minutes. Repeat with remaining batter.
