Preheat and prep
Preheat your oven to 400°F (200°C). Grease a baking dish or cast-iron skillet generously. Cold pans are the enemy—warm ovens only.
Mix the dry ingredients
In a large bowl, whisk together cornmeal, flour, baking powder, salt, and sugar. Keep it simple and evenly mixed. No lumps, no drama.
Add the wet ingredients
Stir in milk, eggs, and melted butter. Mix just until combined. Overmixing leads to tough cornbread, and nobody asked for that.
Bring in the stars
Fold in shredded cheddar and chopped jalapeños. Make sure they’re evenly distributed so every bite gets some love.
