Preheat the oven to 400°F. Line muffin cups with paper liners and coat the liners with cooking spray.
Whisk together the cornmeal, baking powder, baking soda, sugar, and salt in a medium bowl.
Whisk together the buttermilk, oil, and eggs in a large bowl.
Add the dry ingredients to the buttermilk mixture and whisk just until combined.
Divide the batter between the muffin cups, filling almost full. Bake for 15 minutes or until golden brown and a toothpick inserted in the center comes out clean.
Serve with a drizzle of honey and butter if desired.
