Heat oven to 375°F. Grease a 9 x 5-inch loaf pan. Line pan with parchment paper if you have it, if not, don't worry about it. The parchment paper just makes it easier to remove from the pan.
Whisk together flour, baking powder, and salt in a large bowl. Add jalapeños, vegetable oil, and honey. Pour in beer and stir to combine.
Scrape into baking pan. Sprinkle top with turbinado sugar and bake 50-60 minutes or until a toothpick inserted in the middle comes out clean and bread sounds hollow when you tap on it.
Let cool in the pan 10 minutes, then remove and let cool completely on a wire rack. Slice and eat warm with melty butter.
