In a medium bowl, beat the egg. Mix in the whole milk.
Mix in the flour and the baking powder, and If using, the optional add-ins.
Mix in the butter.
Heat a griddle to medium heat and lightly grease the pan. To make 1-inch pancakes (like in the photos), drop on the pancake batter using a teaspoon. To make 2-inch pancakes, drop on the pancake batter using a tablespoon.
Cook, until the tops of the pancakes have bubbles on them, the batter is no longer shiny, and the bottom of the pancakes are a light golden brown, about 45 seconds to 1 minute. Flip and cook for an additional 45 seconds to 1 minute, until the bottoms are also golden brown. Remove from heat and set on a plate to cool.
Serve with a dollop of plain greek yogurt and fresh berries.
