Preheat your oven to 400°F (200°C) to ensure even baking and a golden crust.
In a large mixing bowl, whisk together the all-purpose flour, granulated white sugar, baking powder, and salt until well combined.
Gently fold in the chocolate chips, chopped toasted walnuts, and chopped Heath or Skor Bars (or toffee bits) evenly throughout the dry mixture.
In a separate bowl, combine the chilled heavy whipping cream and melted unsalted butter, stirring until fully incorporated.
Pour the wet ingredients into the dry ingredients and mix gently until just combined; the dough should be slightly sticky and thick with some lumps.
Turn the dough out onto a lightly floured surface and gently shape it into a 1-inch thick circle using floured hands. Cut the circle into 8 wedges with a sharp knife or pizza cutter.
Transfer the scones to a parchment-lined baking sheet and sprinkle granulated or coarse white sugar on top of each wedge.
Bake in the preheated oven for 18-20 minutes, or until golden brown and a toothpick inserted in the center comes out clean.
Remove scones from the oven and cool on a wire rack for at least 10 minutes before serving. Enjoy warm with butter, honey, or on their own.
