01 - Preheat oven to 350°F. Grease and line a 9x5-inch loaf pan with parchment paper.
02 - In a large bowl, whisk together flour, baking powder, baking soda, salt, pepper, and smoked paprika.
03 - In a separate bowl, whisk eggs, milk, and melted butter until fully incorporated.
04 - Add the wet ingredients to the dry mixture and stir gently, mixing only until just combined. Avoid overmixing.
05 - Fold in the grated cheddar, corn kernels, scallions, jalapeño, and herbs, if using.
06 - Transfer the batter into the prepared loaf pan. Smooth the surface and sprinkle extra cheddar on top if desired.
07 - Bake for 40 to 45 minutes, or until a skewer inserted in the center emerges clean and the top is golden brown.
08 - Leave to cool in the pan for 10 minutes, then remove to a wire rack and cool completely before slicing.
