Combine pastry flour with the baking powder and salt. Add the milk, egg, melted butter, and maple syrup. Give a good stir, until everything is just combined but there might few small lumps left. Let rest while heating the griddle or pan.

Heat a skillet or griddle over low to medium-low heat and grease with butter or oil if need be. When skillet is hot (if you flick water onto the skillet, it should sizzle), take a scant ¼ cup of batter and pour onto skillet. Let cook for 1-2 minutes (until the pancakes begins to bubble slightly. Flip and let cook for another 1-2 minutes until pancake is cooked through.

To make the topping, cut or cube the persimmon into slices or pieces. Melt the butter in a pan and add the persimmons along with the maple syrup, cinnamon, and salt. Cook, stirring occasionally, until the persimmons are starting to soften but still have a bit of firmness.

To finish the pancakes, top with the persimmons, a sprinkle of the toasted walnuts, and a sprinkle of cinnamon.
