Start by preheating your oven to 375°F and lining a cookie sheet with parchment paper.
In a large mixing bowl, whisk together flour, granulated sugar, baking powder, and salt. Cut in the cold butter until the mixture resembles coarse crumbs.
Pour heavy cream into a measuring cup, add 1/2 teaspoon vanilla extract, and stir. Gradually mix this into the dry ingredients until just combined, being careful not to overwork the dough.
Transfer the dough to a floured surface. Scatter the berries on top and gently fold them into the dough.
Divide the dough in half, shape each half into an 8-inch round disc, and cut each disc into 8 wedges. Place the wedges on the prepared cookie sheet.
Bake in the preheated oven for 18-20 minutes or until the scones are golden brown and baked through.
