Slice a small opening along the top of each date and remove the pit. Check that the inside is clean.
Press gently on the top and bottom of each date to form a heart shape.
In a small bowl, whisk tahini, date syrup, and maple syrup until smooth. If the mixture is too loose, stir in almond flour a little at a time until it holds shape.
Cover each date with about 1 teaspoon of the nut caramel, pressing lightly to close.
Dip each filled date into melted dark chocolate, allowing excess to drip off.
Place the coated dates on a parchment-lined tray and sprinkle with crushed nuts, coconut, or pistachios.
Refrigerate until the chocolate is set, about 20 minutes. Serve chilled.
