Preheat oven to 325F.
In a dry skillet over medium heat, toast sesame seeds, stirring frequently, until fragrant. Remove from heat and let cool. Add to a medium mixing bowl and add the coconut flour, coconut sugar and salt. In a small saucepan over low heat, melt the coconut oil, then stir in the coconut milk and vanilla. Pour over the dry ingredients and stir well to fully combine.
Place the mixture on a piece of parchment paper, then place another sheet of parchment on top and roll out until very thin.
Remove the top piece of parchment, then slide the bottom piece with the dough onto a baking sheet and place in the oven. Bake for 10-15 minutes until golden around the edges.
Remove from oven and slide the parchment onto a cooling rack. Let cool completely, then break into shards and store in a very airtight container. Keeps for 1 month.
