Begin by preheating the oven to 425°F. Line a baking sheet with parchment paper and set aside.
In a large mixing bowl, combine the all purpose flour, baking soda, baking powder, and salt.
Using a pastry cutter, or fork cut in the cold butter until the butter is in small pea sized pieces.
In a separate medium bowl, combine the pumpkin puree and Greek yogurt.
Add the wet ingredients to the dry ingredients. You may find it is easier to use your hands.
Knead dough out onto a floured surface a few times. Pat the biscuits into a disk about ¾ inch thick. Cut out circles of 2-3 inches in diameter.
Transfer circles to baking sheets, brush the tops with melted butter.
Bake for 12-14 minutes, until biscuits are firm to the touch and cooked through.
Cool slightly and serve.
