Preheat your oven to 375°F (190°C).

In a large mixing bowl, whisk together the flour, baking powder, salt, and sugar until well combined.

Stir in the shredded cheddar cheese and chopped jalapeños, ensuring they are evenly distributed throughout the dry mixture.

In a separate bowl, pour in the beer and melted butter. Gently mix to combine.

Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Be careful not to overmix; the batter should be slightly lumpy.

Grease a loaf pan or line it with parchment paper. Pour the batter into the pan, spreading it evenly.

If desired, sprinkle additional cheddar cheese and jalapeño slices on top of the batter for an extra flavor punch.

Place the loaf pan in the preheated oven and bake for 45-55 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.

Once baked, remove the bread from the oven and let it cool in the pan for about 10 minutes before transferring it to a wire rack. Allow it to cool slightly before slicing.

Serve warm with butter or your favorite dip. This bread pairs perfectly with soups, chili, or simply on its own!
