Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a large mixing bowl, whisk together the all-purpose flour, brown sugar, baking powder, baking soda, salt, ground cinnamon, nutmeg, ginger, and cloves.

Add the cold, unsalted butter to the dry mixture and cut in until resembling coarse crumbs.

In a separate bowl, combine pumpkin puree, buttermilk, and vanilla extract; whisk until smooth.

Gently pour the wet mixture into the dry ingredients and stir until just combined.

Turn the dough onto a lightly floured surface and pat into a rectangle about 1-inch thick, then cut out rounds or squares.

Place the cut biscuits on the prepared baking sheet and bake for 12-15 minutes.

Let the biscuits cool slightly on a wire rack before serving.
