Preheat oven to 375 degrees. Line a baking sheet with parchment paper and set aside. In a small bowl or cup combine 1 teaspoon of sugar and 1 tablespoon of milk, set aside. In a large bowl combine flour, 1/4 cup of sugar, baking powder and salt - whisk ingredients together. Either using a food processor or 2 forks (by hand) cut the butter into the flour mixture until combined and a crumbly texture forms. Make a well in the center of the flour mixture and add in milk and extracts. Use a wooden spoon to stir the mixture together until a shaggy dough forms. Toss in sprinkles, mix to combine,
Place the dough on a heavily floured surface and knead dough with your hands to 1 to 2 minutes. Pat dough into a 9 inch circle, about 1 inch thick. Cut into 8 wedges. Transfer wedges onto the baking sheet and brush with the sugar/milk mixture from step 1.
Baking until lightly golden, about 30 minutes. I took mine out of the oven around 26 minutes so check after 25 minutes for doneness.
Allow scones to cool on a cooling rack for about 10 minutes.
Assembly the glaze: in a small bowl combine confectioner's sugar, milk, vanilla extract & salt into a bowl. Whisk ingredients together and drizzle over scones before serving.
