Preheat the Oven: Begin by preheating your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt until well combined.
Add Butter: Using a pastry cutter or your fingers, cut in the cold cubed butter until the mixture resembles coarse crumbs.
Incorporate Cheese and Sausage: Fold the shredded cheddar cheese and crumbled sausage into the flour mixture, ensuring even distribution.
Add Buttermilk: Pour in the buttermilk and gently mix until just combined. Avoid overmixing to keep your biscuits light and fluffy!
Shape the Biscuits: Turn the dough out onto a floured surface and pat it into a rectangle. Cut out biscuits using a round cutter or simply slice them into squares.
Bake: Place the biscuits on the prepared baking sheet and bake for 15-20 minutes, or until they are golden brown.
Cool and Enjoy: Allow the biscuits to cool slightly before serving. They’re best enjoyed warm!
