Preheat oven to 450°F (230°C). Line a baking sheet with parchment paper.
In a large bowl, whisk together flour, baking powder, baking soda, and salt.
Using your fingers or a pastry blender, cut the cold butter into the dry ingredients until it resembles coarse crumbs.
Pour the buttermilk into the dry ingredients and stir until just combined. The dough will be sticky.
Shape biscuits: Turn the dough out onto a lightly floured surface. Gently pat it into a 1-inch thick circle. Use a 2.5-inch biscuit cutter to cut out biscuits.
Place the biscuits on the prepared baking sheet, spacing them about 1 inch apart. Bake for 12-15 minutes, or until golden brown.
Serve warm with butter and honey or your favourite jam.
