In a large bowl, combine the flour, sugar and baking powder. Cut in butter until mixture resembles coarse crumbs. In a small bowl, whisk eggs and milk; stir into crumb mixture just until moistened. Fold in hazelnuts and currants (dough will be sticky).
Turn onto a floured surface; knead 8-10 times. Pat into an 8-in. circle. Cut into eight wedges. Separate wedges and place on a greased baking sheet. Bake at 375° for 12-18 minutes or until golden brown. Serve warm.
