Making Biscuit Breakfast Sandwiches is a breeze when you follow these simple steps:

1. Preheat Oven: Preheat your oven to 450°F (232°C). Line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
3. Cut in Butter: Add the cold, cubed butter to the flour mixture. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs.
4. Add Buttermilk: Pour in the buttermilk and stir until just combined. Do not overmix; the dough should be slightly sticky.
5. Shape Biscuits: Turn the dough onto a floured surface. Gently pat it into a rectangle about 1 inch thick. Use a biscuit cutter to cut out biscuits and place them on the prepared baking sheet.
6. Bake Biscuits: Bake for 12-15 minutes or until the tops are golden brown. Remove from the oven and let cool slightly.
7. Cook Sausage or Bacon: Meanwhile, cook the sausage patties or bacon in a skillet over medium heat until fully cooked and crispy.
8. Scramble Eggs: In a bowl, whisk the eggs with a pinch of salt and pepper. Scramble in the same skillet until cooked to your liking.
9. Assemble Sandwiches: Slice each biscuit in half. Layer the bottom half with cheese, sausage or bacon, scrambled eggs, and any additional toppings.
10. Top and Serve: Place the top half of the biscuit on the sandwich and serve warm.
