Step 1 Whisk eggs and cinnamon in shallow bowl until blended. Whisk in milk and vanilla.
Step 2 Spray large skillet with cooking spray. Heat skillet over medium heat.
Step 3 Dip one slice of bread at a time into egg mixture, turning to coat both sides. Remove from egg mixture, letting excess drip off. Place bread on hot skillet. Cook until bottom is golden brown, 1 to 2 minutes. Turn over and cook other side until browned.
Step 4 Remove bread from skillet and place on cutting board. Cut each slice into three equal strips, then each strip into three cubes. Cut each banana into six slices.
Step 5 Thread a cube of bread onto 8-inch (20 cm) wooden skewer. Alternately add fruit and bread so skewer has three bread cubes and three portions of fruit. Repeat with remaining bread cubes and fruit, making 12 skewers.
