In a small bowl, stir the pancake mix, water and banana just until moistened.
Pour a scant 1/2 cup batter onto a greased hot griddle, making three circles to form a snowman. Turn when bubbles form on top. Cook until the second side is golden brown. Transfer to a serving plate. Repeat with the remaining batter.
Sprinkle with confectioners’ sugar. Decorate snowmen with pretzels, chocolate chips, cranberries and/or banana if desired.
