To a large bowl, add mashed banana, egg, tahini, olive oil and vanilla. Whisk to combine until smooth.
Add dry ingredients up to the carrot and mix until almost thoroughly combined.
Add carrot and dates and mix until fully incorporated.
Allow the dough to rest for approximately 10 minutes.
Use an ice cream scoop to measure out dough onto the prepared cookie sheet.
With a damp hand, gently flatten and shape into circles.
Bake for 15 minutes or until the cookies start to brown and are dry to the touch.
Transfer to a wire rack to cool for 10-15 minutes before enjoying.
Once cool, store in an airtight container.
