You can either use a bread pan or a cast-iron skillet for baking this. If you use a cast iron, put it in the oven and preheat at 400F. If you use a bread pan, grease it with butter set it aside and preheat the oven. I like to be extra careful and add parchment paper and oil it, this way it’s nearly impossible for it to stick.
In a mixing bowl, combine the baking powder, flour, cornmeal, salt and sugar.
In another bowl combine the egg, milk and melted butter.
Pour the liquid mix into the dry mix and stir until it’s all combined. Do not over stir or it will develop gluten and it will be crumbly
Mix in the jalapenos and cheddar
If you use a bread pan, pour into it and place it in the oven. If you use a cast-iron skillet, remove it from the oven, carefully give it a light oil coating and pour the liquid in

Remove from the oven and let it sit for 2 minutes then place the bread on a wire rack to cool completely
