Combine dry ingredients in a food processor and pulse to combine.
Add cold butter and pulse until mixture resembles fine meal (you want there to be little chunks of butter left.)
Remove to a good sized bowl.
In a separate bowl beat eggs, milk and molasses together and add to dry mixture.
Stir gently until just combined.
Turn out onto a lightly floured surface and knead gentlya few times until the dough comes together. (Work the dough as little as possible so your scones are light).
Roll out (don’t press too hard) about an inch thick and cut into shapes.
Place them on a parchment paper lined baking sheet and brush with egg wash.
