In 1 1/2-quart saucepan, melt butter over medium heat. Add walnuts; cook, stirring occasionally, just until walnuts and butter begin to brown. Add bananas; stir to coat with butter. Stir in syrup. Reduce heat to low, cook until warm. Keep warm while making pancakes.

Heat griddle or skillet over medium heat or to 375°F. Grease griddle with vegetable oil if necessary (or spray with cooking spray before heating). In medium bowl, stir all pancake ingredients with spoon until well blended.

For each pancake, pour 1/4 cup batter onto hot griddle. Cook until edges are dry. Turn; cook other sides until golden. Serve with the warm syrup.
