Prepare the Biscuit Dough:

1. Preheat the Oven: Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper to prevent the biscuits from sticking.
2. Mix the Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, baking powder, cinnamon, nutmeg, ginger (if using), and salt until well combined.
3. Cut in the Butter: Add the cold, cubed butter to the dry ingredients. Use a pastry cutter or your fingers to work the butter into the flour mixture until it resembles coarse crumbs. You should have pea-sized pieces of butter throughout.
4. Combine the Wet Ingredients: In a separate bowl, whisk together the pumpkin puree, milk, and vanilla extract.
5. Make the Biscuit Dough: Pour the wet ingredients into the dry ingredients. Use a spatula or spoon to stir everything together until just combined. The dough will be slightly sticky.

Shape the Biscuits:

6. Turn Out the Dough: Turn the dough onto a lightly floured surface. Gently fold the dough over itself a few times to bring it together. Be careful not to overwork the dough, as this will make the biscuits tough.
7. Roll and Cut: Roll the dough out to about 1-inch thickness. Using a round biscuit cutter or a glass, cut out biscuits. Press straight down without twisting to ensure the biscuits rise properly.
8. Arrange the Biscuits: Place the biscuits on the prepared baking sheet, close together so they can bake with soft, golden sides. If you like, brush the tops of the biscuits with a beaten egg for a shiny, golden finish.

Bake the Biscuits:

9. Bake: Bake the biscuits for 18-20 minutes, or until they are golden brown on top. The biscuits should have risen nicely and feel light to the touch.
10. Cool: Allow the biscuits to cool on a wire rack for a few minutes before serving.

Serve:

11. Serve and Enjoy: Serve the biscuits warm with butter, jam, or even a dollop of whipped cream for an extra indulgent treat. These biscuits are perfect on their own or paired with a cup of coffee or tea.
