Preheat the oven to 400 degrees F (200 degrees C). Lightly grease a baking sheet.
Whisk flour, sugar, baking powder, salt, and cinnamon together in a bowl. Cut in butter cubes with a pastry cutter or 2 knives.
Mix half-and-half and egg together in a bowl. Mix into the flour-butter mixture. Fold in blueberries and oats.
Turn dough out onto a lightly floured surface and divide in half. Roll each half into a circle and cut each into 8 wedges. Transfer scones to the prepared baking sheet; sprinkle raw sugar over the top.
Bake in the preheated oven until golden brown, 12 to 15 minutes.
