Step 1

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

Step 2

In a large bowl, combine flour, baking powder, salt and baking soda. Add cold butter, using your fingers to work the butter into the dry ingredients until it resembles coarse crumbs. Add buttermilk and stir using a rubber spatula until a soft dough forms.

Step 3

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 10-12 rounds using a 2 1/2-inch biscuit or cookie cutter. Place biscuits onto the prepared baking sheet.

Step 4

Place into oven and bake for 14-16 minutes, or until golden brown; set aside.

Step 5

Reduce oven temperature to 400 degrees F. Line a baking sheet with foil.

Step 6

Place bacon in a single layer onto the prepared baking sheet. Place into oven and bake until almost crisp, about 6-8 minutes. Transfer to a paper towel-lined plate; cut in half crosswise and set aside.

Step 7

Melt butter in a large skillet over medium low heat. Add eggs and cook, stirring gently using a silicone or heat-proof spatula, until they just begin to set; season with salt and pepper, to taste. Continue cooking until thickened and no visible liquid egg remains, about 4-6 minutes.

Step 8

Split biscuits; top with cheese, eggs and bacon, and then cover with another biscuit top to create a sandwich. Repeat with remaining biscuits to make 12 sandwiches. Wrap tightly in plastic wrap and place in the refrigerator.

Step 9

To reheat, remove plastic wrap from the sandwich and wrap in a paper towel. Place into microwave for 1 minute, or until heated through completely.

Step 10

Serve immediately.
