Soak Cashews and Dates: Place cashews and pitted dates in a bowl and cover with cold water. Let soak for 15 minutes, then drain.

Prepare the Mixture: In a blender, combine soaked cashews, dates, and sugar-free apple syrup. Blend until smooth and well combined.

Form the Bites: Spoon the mixture into an ice cube tray with a silicone bottom. Use your finger or a small spoon to make indentations in the center of each bite. Place the tray in the fridge for 10 minutes to firm up.

Melt the Chocolate: In a heatproof bowl over simmering water (double boiler), melt the sugar-free chocolate. Stir in oat milk until smooth.

Fill the Indentations: Pour the melted chocolate into a piping bag. Carefully pipe the chocolate into the indentations of each cashew-date bite.

Chill and Set: Refrigerate for another 15 minutes or until the chocolate is set.

Serve: Pop the bites out of the tray and enjoy!
