Lightly beat the eggs in a large bowl, and then whisk in all the other wet ingredients.
Mix the dry ingredients in a medium bowl. Add to the wet ingredients and blend well.
Heat a large, heavy-bottomed skillet over medium heat with a couple teaspoons of oil (just enough to coat the pan).
Carefully place a banana slice on the skillet, if using, and then spoon approximately 2 tablespoons of batter over the banana slice. If not using the banana, pour batter directly onto skillet as you would normally do.
When you can slide a spatula under a pancake easily and the bottom is golden, flip the pancake and cook on the other side.
Cook for another minute or two until just cooked through. Repeat for the remaining banana slices and batter. Keep warm in a 200-degree oven if you would like to keep them hot while cooking the rest.
Enjoy with maple syrup or topping of choice. Leftovers may be refrigerated or frozen. I like to reheat in a toaster oven until just hot.
