Stir together the mashed bananas, butter, lemon juice and sugar in a medium bowl.
Beat in the eggs.
Whisk together the oat flour, baking soda, salt and spices in a small bowl.
Form a well in the center of the dry ingredients and pour in the wet ingredients.
Stir the batter just until the dry ingredients are thoroughly moistened.
Check to be sure the batter is thin enough for your pancakes; you may need to add a touch of milk or water (I never do)
Let the batter sit 10 minutes before using.
Heat a nonstick griddle or heavy skillet.
If your surface is not non-stick brush it lightly with vegetable oil.
When the surface is ready spoon batter 1/4 C. at a time into the pan.
Let the pancakes cook on the first side until bubbles begin to for around the edges, 3-4 minutes.
When the pancakes are just beginning to set flip then and let them cook on the second side, about 1 1/2 minutes more.
You can sprinkle toasted walnuts over the batter just before cooking as an extra treat.
