Place the dates (remove stones), nut butter, coconut oil, vanilla, and salt in the bowl of a food processor fitted with the blade attachment.
300 grams (1 ½ cups, packed) soft dates, 2 tablespoons nut butter, 2 teaspoons coconut oil, ½ teaspoon vanilla extract, ¼ teaspoon sea salt
Mix on high until the mixture breaks down and forms a homogenous ball.
Line a bread tin or similar with parchment paper. Press the caramel mixture into the container in an even layer, dampening hands if needed. It should ideally be 2-3 cm thick (about 1 inch).
Freeze for 30 minutes. Remove from the tin and peel the paper off. Cut into small squares, about 2x2 cm (¾ inch). Place back into the freezer until ready to coat in chocolate.
Melt chocolate over a double boiler and use a fork to dip the caramel squares to coat, tapping any extra chocolate off before setting onto parchment or a rack to set. Top with edible flowers or similar if desired.
50 grams (¼ cup) dark chocolate, for coating
Once set, store the caramels in an airtight container in the freezer for up to a month. They're best straight from frozen.
