Preheat your oven to 350°F if using chocolate.
Slice each date lengthwise to create a pocket, being careful not to cut all the way through.
In a small bowl, mix almond butter, walnuts, and cinnamon until well combined.
Stuff each date with approximately 1 tablespoon of almond butter mixture.
(Optional) If you want chocolate, place the stuffed dates on a baking sheet lined with parchment paper.
(Optional) Melt dark chocolate in a microwave-safe bowl in 30-second intervals, stirring in between until smooth.
(Optional) Drizzle the melted chocolate over each stuffed date and sprinkle with a pinch of sea salt.
(Optional) Bake for about 5-7 minutes until chocolate is melted and dates are warm.
Allow to cool slightly before serving; enjoy these delicious bites!
