01 - Preheat oven to 400°F (200°C). Line baking sheet with parchment paper.
02 - In a large mixing bowl, whisk together flour, baking powder, salt, black pepper, and smoked paprika until evenly distributed.
03 - Add cold butter cubes to the dry mixture. Use a pastry cutter or fingertips to blend until the mixture achieves a coarse, crumb-like texture.
04 - Fold in grated cheddar and chives or scallions, if desired.
05 - In a separate bowl, whisk pumpkin puree, heavy cream, and egg until smooth.
06 - Add pumpkin mixture to the flour mixture. Gently mix just until the dough forms; avoid overworking.
07 - Turn dough onto a lightly floured work surface. Pat into a round approximately 1 inch thick.
08 - Cut dough into 8 equal wedges. Arrange on the prepared baking sheet, allowing space between each.
09 - Brush tops with heavy cream and sprinkle with extra cheddar as desired.
10 - Bake for 18–20 minutes, or until golden and firm. Let cool slightly before serving.
