Directions
1Whisk the dry ingredients together in a bowl.
2In a separate bowl, whisk together the cold milk and cold sour cream. Slowly pour in the warm melted butter while stirring until the mixture forms small clumps.
3Fold the wet ingredients into the dry ingredients just until the flour disappears.
4Scoop 10 equal mounds of dough, about 110 g each, onto a parchment-lined baking sheet, leaving room between them, and lightly flatten.
5Bake at 425°F (conventional) or 400°F (convection) until the tops and bottoms are golden and the centers are set.
