01 - Preheat oven to 400°F. Grease an 8-inch square baking pan or 9-inch round skillet with cooking spray or butter.
02 - In a large mixing bowl, whisk together all-purpose flour, yellow cornmeal, granulated sugar, baking powder, and salt until evenly distributed.
03 - In a separate medium bowl, beat eggs lightly. Whisk in whole milk, vegetable oil, and melted unsalted butter until smooth and fully incorporated.
04 - Pour wet ingredients into dry ingredients. Stir gently with a spatula or wooden spoon until just combined, being careful not to overmix.
05 - Gently fold chopped jalapeños, corn kernels, and shredded sharp cheddar cheese if using into the batter until evenly distributed.
06 - Pour batter into prepared baking pan or skillet. Spread evenly with a spatula, ensuring the surface is level.
07 - Bake for 22-25 minutes until top is golden brown and a toothpick inserted into the center comes out clean.
08 - While cornbread bakes, combine honey, fresh lime juice, lime zest, and pinch of salt in a small saucepan over low heat. Warm gently for 2-3 minutes until fluid and fragrant, stirring occasionally.
09 - Remove cornbread from oven. While still warm, drizzle lime honey glaze evenly over the top. Let cool for 5-10 minutes before slicing and serving.
