Mix together the flour, sugar, baking powder, baking soda, salt and cinnamon. Once that’s mixed, cut in the butter till the mixture is crumbly like a pie crust.
Then mix together the milk, lemon juice and vanilla.
Stir the wet mixture into the dry, and then stir in the chips.
After a few stirs, put the mixture out onto a floured surface, and gently knead for just a minute, till everything comes together.
Divide up the dough into two equal size balls.
Then roll the balls into two 7 to 8 inch circles (around an inch thick), and cut into 6 or more wedges each. Place them onto a lightly greased baking sheet, or on parchment paper (on a baking sheet). Stick in freezer for 15 to 30 minutes.
Bake in a preheated 425 degree oven for around 20 minutes or till golden.
Stir together the powdered sugar, milk, vanilla and salt, and then using a pastry brush, thoroughly coat the fresh out of the oven scones.
