Preheat the oven to 400 degrees.
In a medium-large bowl, whisk together dry ingredients (flour, sugar, baking powder) and set aside.
Next, chop the cold butter into small pieces. Use your fingers, forks, or a pastry cutter to work the butter into the dry ingredients until the mixture resembles coarse sand. Any leftover butter chunks shouldn't be larger than a pea. Set aside.
In a separate bowl, mix together wet ingredients (cream, eggs and vanilla extract).
Add the wet ingredients to the flour mixture and mix together until all of the dry ingredients have been coated to form a dough. *I usually use my hands at the end of mixing to make sure everything is well incorporated
Fold in the white chocolate chips and frozen raspberries with your hands or a large spoon.
Line a large cookie sheet with parchment paper. Lightly flour the parchment paper.
Next, lightly flour your hands and pick up the dough and place it on the lined cookie sheet. Form the dough into an 8-9 inch circle (about 1-1 ½ inches thick) using a rolling pin or by just pressing it down with your hands. Sprinkle more flour as you go if necessary.
Place the cookie sheet with the circle of dough in the freezer for 10-15 minutes to set.
Remove the dough from the freezer and use a knife or a pizza cutter to slice the scone dough into 8 equal pieces.
Evenly space the scones on the large cookie sheet, leaving at least an inch in between each scone. Brush them with heavy cream and bake for 15-20 minutes or until the bottom and edges of the scones are golden brown.
Remove them from the oven and allow them to cool to room temperature before adding the icing.
