Preheat oven to 450 degrees F. Line a baking sheet with parchment paper or a silicone baking mat.

Heat a large skillet over medium high heat. Add bacon and cook until brown and crispy, about 6-8 minutes. Drain excess fat; transfer bacon to a paper towel-lined plate.

In a large bowl, combine bacon, flour, cheese, baking powder, salt and baking soda.

Grate butter using the large holes of a box grater. Stir into the flour mixture.

In a medium bowl, whisk together buttermilk and 4 tablespoons maple syrup. Add to the flour mixture and stir using a rubber spatula until a soft dough forms.

Working on a lightly floured surface, knead the dough 3-4 times until it comes together. Using a rolling pin, roll the dough into a 1 1/4-inch thick rectangle. Cut out 12 rounds using a 2 to 2 1/2-inch biscuit or cookie cutter. Place biscuits onto the prepared baking sheet; place in the freezer for 15 minutes.

Remove biscuits from freezer. Place into oven and bake for 15-18 minutes, or until golden brown.

In a small bowl, whisk together remaining 2 tablespoons maple syrup and butter.

Serve biscuits warm, brushed with the maple-butter mixture.
