Using two knives or a pastry cutter, cut in the coconut oil until there are no clumps larger than pea size.
Add the coconut milk and agave nectar to your flax egg and stir to combine. Pour the wet ingredients into the dry ingredients and mix until just incorporated.
Fold in the craisins.
Place the dough in the middle of your baking sheet and use your hand to flatten it into a circle about 1 ½ inches high. Cut the dough into 6-8 equal wedges, but keep the dough together in a circle.
If using the coarse sugar, sprinkle 1 tablespoon on top of the wedges and gently press it into the dough so they don't rub off.
Bake for 17-20 minutes until the scones are cooked through and the bottom is golden.
