1Stir baking mix, milk, sugar, egg, and vanilla extract together in a bowl until batter is smooth; fold in banana and chocolate chips until just combined.
2Heat a non-stick pan over medium-high heat. Sprinkle a few drops water in skillet; they will dance and disappear when skillet is ready.
3Spoon just under 1/4 cup batter into the pan; cook until bubbles appear on the top of each pancake and bottom is golden brown, 3 to 4 minutes. Flip each pancake and cook until bottom is golden brown, 3 to 4 minutes. Repeat with remaining batter.
You could also add 1/3 cup unsweetened baking cocoa powder for a more chocolaty taste.
