Heat oven to 375ºF. Line a loaf pan with foil and spray with cooking spray.
In a large mixing bowl, combine the flours, sugar, baking powder, and salt. Pour in the beer and mix to form a thick batter. Fold in the cheddar shreds, jalapenos, and scallions.
Pour the batter into the prepared loaf pan; brush the top with butter or margarine.
Bake for 40 minutes, or until cooked through. Remove from oven and let cool 5-10 minutes before slicing.Recipe by: Healthy Delicious
