Set the oven to 400 degrees.
Combine flour, white sugar, 1 tsp. of cinnamon, salt, and baking powder.
Add the 2/3 cup of softened butter and cut into the flour mixture until evenly distributed.
Slowly add the whipping cream and stir until combined. Don't overmix.
Remove the dough from the mixing bowl, knead a few times on a floured surface, and then shape it into a large ball.
Divide the dough into 2.
Roll each half into a 10-inch circle.
On one circle, spread 2 tbsps. of soft butter over the surface.
Sprinkle the 1/2 cup of brown sugar, 1/2 tsp. cinnamon, and raisins (optional) evenly over the butter.
Set the other dough circle on top.
Seal the dough around the edges as shown in the photo.
Cut it into 12 triangles.
Place triangles on parchment paper, tucking in the corners slightly to help keep their shape.
Bake for 15-20 minutes or until lightly browned on top and sides.
While the scones are baking, combine the remaining 3 tbsps. of butter, powdered sugar, and enough milk or cream to make an icing. Thicker icing stays on the scones better.
While the scones are still warm, pour the icing on top.
Enjoy!
