Preheat your oven to 400°F and prepare a baking sheet with parchment paper.

In a spacious bowl, combine the flour, baking powder, sea salt, and black pepper, mixing well.

Incorporate the cold, diced butter into the flour mixture until it resembles small pebbles.

Gently fold in the cottage cheese, chopped bacon, and sliced scallions until just combined.

In a separate bowl, whisk the egg and buttermilk together, then pour into the dough and fold until unified.

Transfer the dough onto a lightly floured surface and shape it into a round disc about 1-inch thick.

Cut the disc into 8 equal triangles and arrange them on the prepared baking sheet.

Bake for 15-20 minutes, or until the tops are golden and the biscuits are cooked through.

Let them cool for a few minutes on a wire rack before serving warm.
