Place all ingredients in a food processor and blend until dates are processed and an even, crumbly mixture forms. The mixture needs to hold, so press some dough in your hand and see if you can roll it into a ball. If not, add a touch more maple syrup.
Pour out the dough and, using a spoon or small ice cream scooper, scoop small amounts to roll in the palm of your hand. Press gently to flatten each ball and make a cross-hatched pattern on each cookie with a fork.
Melt dark chocolate in the microwave and dunk the cookies in part way. Decorate with crushed peanuts and freeze-dried raspberries.
