Preheat the oven: Start by preheating your oven to 375°F (190°C). Grease a 9-inch baking dish or a cast iron skillet with cooking spray or butter to ensure the cornbread won’t stick.
Mix dry ingredients: In a large mixing bowl, combine 1 cup all-purpose flour, 1 cup yellow cornmeal, 1/4 cup granulated sugar, 1 tbsp baking powder, and 1/2 tsp salt. Stir until well-mixed.
Whisk wet ingredients: In another bowl, whisk together 1 cup buttermilk, 1/4 cup melted unsalted butter, and 2 large eggs until fully combined.
Combine wet and dry ingredients: Pour the wet mixture into the dry ingredients and fold gently. Be careful not to overmix; it’s okay if there are a few lumps!
Fold in extras: Gently fold in 1 cup corn kernels, 2-3 finely chopped jalapeños, and 1/2 cup shredded cheddar cheese until evenly distributed throughout the batter.
Pour the mixture: Transfer the batter to your prepared baking dish, spreading it out evenly with a spatula.
Bake: Place in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Prepare the glaze: While the cornbread is baking, whisk together 1/4 cup honey and the zest and juice of 1 lime in a small bowl until smooth.
Cool and glaze: Once the cornbread is baked, allow it to cool for 5 minutes before drizzling the lime honey glaze over the top.
Slice and serve: Cut into squares and serve warm, ideally with a side of chili, barbecue, or on its own.
