Chop apples into small chunks and place in a small bowl. Pour amaretto over apples, mix to combined. Set aside and allow apples to soak for at least 30 mins.
Combine flour, sugar, baking powder and salt in a large bowl. Whisk to combine.
Grate the frozen butter into the flour mixture. Toss with your hands, then, using a pastry cutter (or two knives), work the mixture until it resembles coarse meal.
Mix in apples and amaretto.
In a small bowl, whisk together cream and vanilla. Slowly combine the cream with the flour and apple mixture until it's just barely combined. Work the dough into a ball. You do not want to over mix.
Transfer to a baking sheet lined with parchment, and press the ball into an 8-inch disk. Cut the disk into 8 equal wedges.
Bake for 20-25 minutes, or until lightly golden. Allow the scones to cool slightly before you add the glaze.
