Preheat oven to 375F and spray a baking sheet with nonstick cooking spray. Set aside.

Mix the flour, sugar substitute, baking powder, salt, and pumpkin seeds together in a large bowl before stirring in the pumpkin and Greek yogurt.

Work the dough together until a dough begins to form. Don't over mix. There should be some dry flour left in the bowl.

Transfer the dough to a flat surface and use your hands to work everything together until no crumbs remain. Press the dough into an 8"x5" rectangle. (You can spray your hands with a bit of cooking spray or lightly flour them to prevent any sticking, if needed.)

Cut the dough into 6 pieces and transfer to the baking sheet. Spray the top with cooking spray (I used olive oil) or brush with oil, butter, or an egg yolk wash.

Bake for 18-20 minutes or until the biscuits are golden brown around the edges and have slightly crisp bottoms.
