Begin by preheating your oven to 400°F (200°C). Prepare an 8-inch square baking dish or a cast iron skillet by greasing it generously with butter or oil.
In a large mixing bowl, add the cornmeal, flour, baking powder, salt, and baking soda. Whisk these dry ingredients together thoroughly until they are well combined and free of lumps.
In a separate bowl, blend the buttermilk, melted butter, and eggs together. If you choose to use honey for a touch of sweetness, incorporate it at this stage and whisk until the mixture is smooth and fully combined.
Carefully pour the wet mixture into the bowl of dry ingredients, using a spatula to gently stir until just combined. Be cautious not to over-mix, as this can lead to a denser cornbread.
With a gentle folding motion, add in the shredded cheddar cheese and finely chopped jalapeños, ensuring they are evenly distributed throughout the batter.
Pour the cornbread batter into the prepared baking dish or skillet, using a spatula to smooth the top for an even bake.
Place the dish in the preheated oven and bake for 20-25 minutes. The cornbread will be done when it turns a beautiful golden brown and a toothpick inserted into the center comes out clean.
Once baked, remove the cornbread from the oven and allow it to cool for about 5-10 minutes. This cooling period makes slicing easier and enhances the flavors.
Notes
Serve warm with butter and honey on the side for added flavor.
