Preheat oven to 375 degrees F.
Whisk the egg, sugar, and oil together in a bowl.
Mix the lemon zest and all of the dry ingredients together in a separate bowl and stir with a wooden spoon until all of them are evenly dispersed throughout.
Slowly add the dry ingredients into the egg, sugar, and oil, and mix to create a thick dough. Add the milk and mix well.
Lightly grease a baking pan. Scoop up tablespoonfuls of the dough and drop them one by one in mounds onto the baking sheet, leaving 2 inches of space between. You should have about 10 scones.
Bake for 15-20 minutes, just until the crust is barely golden brown and the dough is dry.
Remove from the oven and let cool for 10 minutes. With a fork mix the Lemon Topping ingredients until the sugar is completely melded in. Drizzle 1 tablespoon ever each scone.
