Step 1: Preheat and Prepare

1. Preheat your oven to 350°F (180°C) and lightly grease a loaf pan or line it with parchment paper.
2. In a large mixing bowl, combine the flour, baking powder, and salt.

Step 2: Incorporate the Butter

1. Add the chilled butter cubes to the flour mixture.
2. Employ a pastry blender or your hands to blend the butter into the flour until the mixture achieves a texture similar to rough crumbs.

Step 3: Add Cheese, Bacon, and Green Onions

1. Fold in the shredded cheddar cheese, chopped bacon, and green onions into the flour mixture.
2. Gently stir to distribute the ingredients evenly.

Step 4: Mix in Buttermilk

1. Pour the buttermilk into the mixture and stir until a soft, cohesive dough forms.
2. Take care not to mix too vigorously to ensure the bread remains soft and tender.

Step 5: Shape and Bake

1. Transfer the dough to the prepared loaf pan and spread it evenly.
2. Place in the oven for 40 to 45 minutes, or until a toothpick inserted in the center emerges clean and the surface is a golden hue.

Step 6: Cool and Serve

1. Allow the bread to cool in the pan for about 10 minutes before removing it.
2. Slice into thick pieces and serve warm or at room temperature.
