Preheat your oven to 400°F (200°C). Grease a muffin tin or line with paper liners.
In a large bowl, mix together the cornmeal, flour, sugar, baking powder, salt, and fennel seeds.
In another bowl, whisk together the milk, vegetable oil, and beaten egg.
Pour the wet ingredients into the dry ingredients and stir until just combined.
Spoon the batter into the prepared muffin tin, filling each cup about ⅔ full.
Bake for 15-20 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the tin for a few minutes, then transfer to a wire rack to cool completely.
