Preheat the oven to 400 degrees. Line a baking sheet with a silpat mat.
Combine the flours, baking powder, and salt together in a bowl. Cut in the butter with a pastry blender or two knives until the mixture resembles course meal. Place into the refrigerator for 10 minutes to chill. In a smaller bowl, combine the buttermilk and honey and whisk until well blended. Add the buttermilk mixture to the flour mixture and stir until mixed.
Place the dough on a well floured surface and knead 4-5 times. Using a rolling pin, roll the dough into a 9 x 5 inch rectangle. Dust the top with flour then fold the dough crosswise into thirds (like folding a letter to fit into an envelope). Re-roll the dough into a 9 x 5 rectangle, dust the top with flour, and fold the dough crosswise into thirds again. Gently roll or pat the dough into a 3/4 inch thickness and cut with biscuit cutter to form biscuits. Place dough rounds 1 inch apart on the baking sheet.
Bake for 11-13 minutes or until golden brown. Cool two minutes on a wire rack then serve slathered with butter. Enjoy.
