Place 4 cups of dates plus the figs in a food processor or blender. Process until combined to form a crust.
Press the crust into a springform pan (that's lined with parchment paper).
Slice 7 of the apples thin. Lay a few of the slices down over the crust to make a layer of apples.
Make the filling by blending 3 apples, the rest of the dates, plus the cinnamon, pumpkin pie spice, vanilla, and lemon juice. Spread this over the layer of apples.
Top with more of the filling, topped with the rest of the apples.
