Preheat oven to 400 degrees. In a large bowl, combine mashed banana, pumpkin, and date paste. Add spices, vanilla, baking powder, cocoa, and flours. Mix together until fully combined. The batter will be a bit sticky. Flour your hands and roll the batter into ten evenly sized balls. Place the balls on a parchment paper lined baking sheet and press them down to flatten slightly. Bake on the middle oven wrack for 15 minutes. Remove from oven and let cool on a wire rack before eating. For even better flavor let them sit overnight in the refrigerator! Store in the freezer or fridge.
