Step 1

Preheat oven to 425 degrees. Line a baking sheet with parchment. In a large bowl, whisk together flour, baking powder, salt, and pepper. Toss butter in flour mixture to evenly coat, then press between your fingers until mixture has the texture of coarse meal, with a few pea-size pieces remaining. In another bowl, whisk together cream and eggs.

Step 2

Make a well in flour mixture; add egg mixture, cheddar, scallions, and dill. Stir together with a fork until dough begins to form but mixture is still crumbly. Turn out onto a lightly floured surface; knead just to combine (do not overwork). Pat out 1/2 inch thick. With a floured 2 3/4-inch biscuit cutter, cut out rounds, as closely together as possible; place on prepared sheet. Gather scraps; pat out again and repeat.

Step 3

Brush tops with cream; sprinkle with more dill and scallions. Bake, rotating sheet halfway through, until golden brown, 23 to 25 minutes. Let cool completely.
