Add the dark chocolate to a microwave-safe bowl and microwave for 30 seconds, then stir. Return to the microwave for another 30 seconds and stir again until fully melted and smooth.
Add the almond butter, Medjool dates, and melted chocolate to a food processor. Blend until the mixture is thick, smooth, and fully combined, with no large pieces of dates remaining.
Line a small tin or dish with parchment paper and transfer the mixture into it, pressing it down evenly with the back of a spoon or spatula.
Place in the freezer for at least 2 hours, or until firm.
Remove from the tin, slice into pieces, and enjoy.
