Mash the bananas with a fork, then add the oats, cinnamon, walnuts and apple. You can add some agave syrup too, but not too much!.
Mix well and rest.
Set the oven temperature to 170°C. Line a baking sheet with parchment paper.
Cut the figs into thin slices.
Make balls from the dough and put them on the baking sheet, then press them down to form circular cookies. Using the agave syrup, glue one slice of fig on top of each cookie, then brush them with the remaining syrup.
Bake for about 20 minutes until the cookies are golden.
Let them cool, then serve (you can brush them again with some syrup, if liked).
