Melt chocolate in 30 second increments until smooth. Stir in tahini until well combined.
In a medium sized bowl, crush the cereal with your hands. Not looking for perfection here, just smaller pieces of cereal.
Pour chocolate & tahini mixture on top, add in hemp seeds and stir to coat.
Place parchment paper on baking sheet.
Line up your dates 3x4.
To make life easier, spray a second piece of parchment with nonstick cooking spray to prevent sticking. Place on top of dates.
Use a flat bottomed ramekin to press down dates. Carefully remove parchment.
Spread the cereal mixture onto the dates, pressing edge to edge with a rubber spatula.
Sprinkle with sea salt and sesame seeds.
Place in the freezer to harden.
Slice as desired and store in an air-tight container in the fridge or freezer.
