01 - Preheat oven to 400°F (200°C). Grease a 12-cup muffin tin or line with paper liners.
02 - In a large mixing bowl, whisk together flour, baking powder, baking soda, kosher salt, and 2 tablespoons granulated sugar.
03 - Add cold cubed butter. Cut in using a pastry cutter or fork until the mixture resembles coarse crumbs.
04 - Stir in shredded sharp cheddar cheese until evenly distributed.
05 - In a separate bowl, beat together whole milk and egg. Pour into dry ingredients and mix gently until just incorporated. Do not overmix.
06 - Divide dough evenly among the prepared muffin cups. Bake for 16 to 18 minutes, or until golden and a toothpick inserted in the center comes out clean. Cool for 5 minutes in pan, then transfer to a wire rack.
07 - While muffins bake, combine 1/3 cup sugar and ground cinnamon in a shallow bowl.
08 - In a small saucepan, melt 1/4 cup unsalted butter over low heat. Stir in pure maple syrup and bourbon until smooth, then remove from heat.
09 - While biscuit muffins are still warm, brush generously with maple bourbon butter using a pastry brush. Immediately roll or sprinkle with cinnamon sugar mixture to coat.
10 - Once cool enough to handle, slice each muffin in half horizontally. Thread 2 to 3 muffin halves onto each soaked wooden skewer, pressing gently to secure.
11 - Drizzle skewers with any remaining maple bourbon butter before serving if desired.
