Preheat the oven to 400 degrees F.
Line a baking sheet with parchment paper or foil.
Place gluten-free flour, shredded coconut, sugar, baking powder, baking soda, xanthan gum and salt into a food processor or blender.
Pulse to combine ingredients.
Add vegan butter chunks and pulse until incorporated into dry ingredients.
Pour vegan buttermilk mixture into the food processor and pulse until a slightly sticky dough forms.
Put a bit of gluten-free flour onto your work surface and carefully turn the dough out onto the surface.
Push dough together and shape into a disc about two inches high and eight inches wide.
Using a sharp knife dipped in water, slice the disc into six equal wedges.
Carefully transfer the wedges to your lined baking sheet, then brush the tops with a bit more coconut milk and sprinkle with a bit more sugar.
Place in the pre-heated oven and bake for about 15 minutes, or until lightly brown and cooked through.
Allow cakes to cool for about 15 minutes, then split horizontally and fill with vegan whipped cream and strawberries. Serve!
