Preheat your oven to 400 degrees.
Prepare a rimmed baking sheet with cooking spray and set aside.
In a large bowl combine the flour, baking powder, salt, and sugar.
Using 2 forks, add butter and mix until it looks like crumbs.
Add buttermilk or heavy cream and stir until blended.
Add coconut and stir until incorporated.
Roll the dough out on a lightly floured surface into a rectangle about 12 by 3 by 1 ¼ inches.
Cut the rectangle into circles using a round cookie cutter.
Place the biscuits on your prepared baking sheet and brush the tops with a little heavy cream.
Bake for 15 to 20 minutes until beautiful and brown.
Let the biscuits cool for 5 to 19 minutes before you drizzle on the glaze.
In a small saucepan, over low heat, combine juice with the powdered sugar until dissolved.
Whisk in the butter and lemon zest if using. Stir constantly until smooth. Drizzle the glaze on top of the scones. Serve and enjoy!
