Flaky Cinnamon Biscuit Rolls

Dough
2 1/4 c white flour
1 tsp salt
4 tsp baking powder
5 TBSP unsalted butter
1 c buttermilk
1/2 TBSP honey

Filling
4 TBSP granulated sugar
1 TBSP cinnamon
4 TBSP softened butter

Glaze
1/8 cup milk
1 tsp maple syrup
1/2-1 cup powdered sugar

Add flour, salt, and baking powder to a medium bowl. Stir to combine. Cut butter into small pieces and add to bowl. Use a fork (and/or your fingers if needed) to mash the butter into the flour until the dough forms pea-sized crumbles. Mix milk and honey in a measuring cup. Add milk to flour mixture and lightly knead, just until moistened. Form a ball and put in the freezer for 10 minutes to chill.

Heat oven to 450 degrees and spray a metal pie pan with cooking spray.  On a floured cutting board, lightly roll dough out into a rectangle about 12"x18". Mix cinnamon and granulated sugar together. Spread butter over the rectangle and sprinkle with cinnamon sugar. Roll dough to form an 18" log. Cut into 8 pieces, a little over 2" each.   
 
Place pieces in pie pan spread apart with the cut side up. Bake 10-12 minutes until the tops are well-browned.
 
Mix milk, syrup and powdered sugar until smooth. Pour over rolls and let stand 10 minutes before serving.
