Preheat your oven to 400°F, line a cookie sheet with parchment paper. I actually preheat my oven while my dough is chilling so it is not on for so long, but that is my preference.
In a large mixing bowl, whisk together the flour, sugar, baking powder, salt, and matcha powder.
Add the cold coconut oil to the dry ingredients. Using a pastry cutter or your fingers, work the coconut oil into the flour mixture until it the coconut oil is thoroughly incorporated and there are no large chunks of it.
Gradually add the coconut milk and vanilla to the dry ingredients, stirring until a dough forms.
Transfer the dough to a floured surface and shape the dough into a rectangle, about 1-inch thick. Note, the dough will be very wet, but that means you’ll have soft, moist scones in the end.
Chill the dough in the freezer for about 30 minutes. Preheat your oven to 400°F if you didn't already.
Cut your scones into triangular wedges. Place triangular wedges on prepared cookie sheet, leaving space between each for spread.
Bake for 15-18 minutes, or until the edges and bottoms are lightly golden.
Remove from the oven and let cool before adding lavender glaze.
