01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, ground cinnamon, and granulated sugar until fully blended.
03 - Add cold, cubed butter to the dry ingredients. Use a pastry cutter or fork to incorporate the butter until the mixture forms coarse crumbs.
04 - In a separate bowl, stir the whole milk and honey together until the honey has fully dissolved.
05 - Pour the milk and honey mixture into the flour and butter mixture. Stir gently with a fork just until a shaggy dough forms, avoiding overmixing.
06 - Transfer dough onto a lightly floured surface. Pat into a 1-inch thick rectangle. Fold the dough in half and pat out again; repeat this process twice more to create flaky layers.
07 - Using a 2.5-inch round cutter, cut out biscuits. Place biscuits onto the lined baking sheet, arranging close together for softer sides or spaced apart for crisper edges.
08 - Bake for 15 to 18 minutes, or until biscuits are golden brown on top.
09 - While biscuits are baking, combine melted butter, honey, and ground cinnamon in a small bowl until smooth.
10 - Immediately brush the warm biscuits with honey butter topping once out of the oven. Serve warm.
