Preheat oven to 400 °F (200 °C). Grease or line a 12-cup muffin pan.

Whisk together cornmeal, flour, baking powder, baking soda, salt, and sugar in a large bowl.

In another bowl, whisk cottage cheese, eggs, buttermilk, and melted butter until combined.

Pour wet ingredients into dry and gently stir until just combined; optionally fold in corn kernels. Do not overmix.

Scoop batter evenly into prepared muffin cups. Bake for 18–20 minutes, until golden and a toothpick comes out clean.

Allow muffins to cool briefly in pan, then transfer to a rack. Serve warm, optionally with butter or honey.
