Preheat the oven to 425 ⁰F degrees and line a 13x18 inch baking sheet with baking parchment and set aside. In a food processor, add the sifted white whole wheat flour, salt, baking powder, baking soda, and sugar.
Toss in the pieces of cold butter and process until the mixture resembles a coarse meal. In a measuring cup, add the cold buttermilk, salt, and vanilla; stir to combine. Then, pour all at once over the flour mixture and pulse until the dough comes together (don't process too much!!!). The dough should be moist.
Transfer the dough to a lightly floured countertop. Pat the dough gently with your hands into a disk that is roughly 1 inch thick. Fold the dough over itself 2 to 3 times; this will help create layers. Dip a 2.5-inch diameter biscuit cutter in flour and cut out the biscuits. Do not twist the biscuit cutter, as this will prevent the biscuits from rising evenly. Gently fold over any remaining biscuit dough and repeat to take roughly 8 to 10 biscuits total.
Alternatively, you can lightly flour your hands or lightly wet your hands and form the dough into 8 balls or use a a¼ cup ice cream scooper and drop/ place on the prepared pan 2 inches apart, sprinkle turbinado sugar on each biscuit, and lightly flatten the surface. Bake for about 10 to 12 minutes, turning halfway through if needed for even cooking. Let cool on a wire rack until serving.
