1. Start with making the crust. Add the graham cracker, melted butter and cocoa powder to a mixing bowl and mix together well.
2. Spoon out mixture and press the base firmly into the bottom and around the edges of a tart tin (rectangle 13 ¾ x 4 ½ inches or circle 9 ½ inches). Place in the fridge to chill.
3. Chop the unsweetened chocolate bar into small chunks and combine with chocolate chips in a bowl. Set aside.
