Place dates in the food processor along with the almond flour and water.
Process on high for one minute.
Sprinkle the contents evenly in 4 cups and press down until formed into a crust.
Cream ToppingPlace 1 cup of cream and 1 tablespoon maple syrup in a blender and blend until thickened into whipped cream.
Scoop out and set aside.
Banana FillingPlace bananas, 1 cup cream, 1 tablespoon maple syrup, 1/2 teaspoon vanilla extract and several drops of natural vanilla food coloring (if using) into the blender and blend until thickened.
Divide the filling between the four cups, then top with whipped cream.
Can be served right away for a light, airy treat, but it becomes thicker and more delicious if chilled for a few hours before serving.
