Start by taking your Medjool dates and using a sharp knife, slice each date down the middle without cutting all the way through.

In a medium bowl, combine the chopped walnuts, chopped pistachios, honey (or maple syrup for a vegan option), cinnamon, and vanilla extract. Stir well.

Using a spoon, take the nut mixture and carefully spoon it into each prepared date.

Once all the dates are filled, arrange them on a serving platter. Chill in the refrigerator for about 30 minutes if preferred.
