Preheat oven to 425 F. Prepare a baking sheet with parchment paper, lightly oil, and set aside.
Combine gluten-free flour, almond flour, baking powder, and salt in a large bowl and mix well.
Cut in butter until the mixture resembles coarse crumbs. Combine almond buttermilk, maple syrup, and pumpkin puree in a medium bowl. Add the buttermilk mixture to the flour mixture and form the dough into a ball.
Roll out dough between 2 oiled sheets of parchment paper, to about 1/2-inch thickness. Using a cookie cutter or drinking glass, cut out biscuit discs of [specific size]. Gather the unused dough scraps, press them together, and roll them out to make extra biscuits. Press 2 biscuit discs together (one on top of the other, making a total of 6–8 biscuits} and place on a baking sheet.
Bake for 15 minutes or until golden brown. Remove from oven and brush with melted butter or coconut oil.
