Preheat oven to 400. Mix together nuts, brown sugar and cinnamon.

In a 10" cast iron skillet bring maple sugar and 4 T butter to a boil. Top with 1/3 of nut mixture.

Combine flour, baking powder and salt in a large bowl. Add 7 T of cold butter and cut in with a pastry cutter and mix until mixture resembles small peas. Add milk and stir gently until mixture comes together. You may have to use floured hands.

Melt remaining 1 T butter.

Turn dough out onto a floured surface and knead gently. Roll into a 9 x 12" rectangle. Brush with melted butter.

Cover dough with remaining nut mixture, patting it gently onto the dough. Roll up dough to form a 12" log, pinching seam to seal. Cut into 12 1" slices and place in skillet. Bake for 20-25 minutes. Remove from oven and serve immediately OR turn out of skillet onto a big plate OR see my notes above!
