Preheat oven to 37 degrees and line a baking sheet with parchment paper.
In a glass measuring jar or a bowl, combine coconut milk with lemon juice and set in the fridge to stay chilled. This becomes your "buttermilk."
In a large bowl, combine flour, baking powder, salt, coconut flakes, and lavender.
On a separate small plate, sift lemon zest with sugar until evenly distributed. Add to the dry ingredients. I find that mixing the zest and the sugar helps it meld into the dough much more nicely!
Cut the cold butter into the dry ingredients with your hands or a pastry cutter until only pea-sized bits are visible. I usually slice chunks to more easily work with them rather than just dumping the whole stick into the floury wad. You can also try grating it.
Pour in coconut "buttermilk" and stir until dough just comes together but is still shaggy. Do not overmix.
Turn dough onto a floured surface. Pat into a rectangle about 10 x 8 inches in measurement. With a sharp knife, slice into 9 scones. Transfer to baking sheet, leaving about 1 inch of space in between them. Bake 18-20 minutes until the bottoms are golden brown. Remove from oven. Cool for about 5 minutes on the sheet, then move to a wire rack.
While the scones bake, prepare the glaze. Melt white chocolate chips in the microwave in :30 increments, stirring after each, until smooth. Let cool five minutes. Stir in powdered sugar and enough milk to thin into a glaze - I used about a tablespoon.
Drizzle warm scones with glaze and top with additional dried lavender, as desired. Serve warm with butter, coffee, or tea.
