Step 1: Preheat your oven to 350°F (175°C) for even baking.
Step 2: If using whole dried dates, process them in a food processor until they form a sticky paste.
Step 3: In a large mixing bowl, mash the ripe bananas until smooth.
Step 4: Add the date paste, applesauce, cinnamon, and vanilla to the mashed bananas. Mix until well combined.
Step 5: Gradually stir in the rolled oats, adding more if the mixture is too wet.
Step 6: Drop spoonfuls of the mixture onto a lined baking sheet, flattening slightly.
Step 7: Bake for 15-20 minutes until edges are golden and centers are set.
Step 8: Let cool on the baking sheet before transferring to a wire rack.
