Preheat your oven to 450°F (232°C) and prepare a baking sheet lined with parchment paper.

In a large mixing bowl, whisk together all-purpose flour, yellow cornmeal, baking powder, baking soda, and salt.

Add the cold, cubed butter to the dry mixture and blend until it resembles coarse crumbs.

Stir in the shredded cheddar cheese and chopped fresh chives until evenly distributed.

Gradually pour in the cold buttermilk and mix until a sticky dough forms.

Lightly knead the dough on a floured surface and pat down to about ½-inch thickness.

Cut out biscuits using a biscuit cutter and place them on the prepared baking sheet.

Bake for 15 minutes or until the biscuits are golden brown on top.

Brush the tops of warm biscuits with melted butter for added flavor.
