Preheat oven to 400 degrees Fahrenheit and line a baking sheet with parchment paper.
In a small mixing bowl, whisk the flax seed with the water (to make the flax egg) and set aside for 3 minutes.
In a separate mixing bowl, add room temperature coconut oil, nut milk, cane sugar, and the blood orange juice. Whisk together, then whisk in the flax-egg.
Mix the flour, baking powder, and salt in a separate bowl. Then add to the wet ingredients a little at a time while stirring with a spatula, or wooden spoon. (If adding raspberries, add now by gently stirring in to incorporate).
Gently transfer the mixture to a floured surface and use your hands to form it into a disc, about 1 inch in height.
Cut the circle into 8 for wedges and use a floured spatula to transfer the scones to the prepared baking sheet. Sprinkle the tops with a bit more cane sugar and bake for 25 minutes, or until lightly golden brown on the edges.
Remove the scones from the oven to cool. While the scones are cooling, prepare the glaze by whisking the powdered sugar with blood orange juice. Drizzle the glaze on top of the cooled scones before enjoying.
Best when fresh; store leftovers at room temperature in a well-sealed container for up to 3 days.
