Preheat oven to 350ºF (180ºC ) and arrange an oven rack in the center position. Grease a 9” loaf pan with butter or cooking spray. Line with parchment paper.
Add dry ingredients (whole wheat flour, oats, baking soda, salt, brown sugar) into a large bowl and whisk to fully combine.
Add wet ingredients (ale, buttermilk, molasses, melted butter, honey) to the dry ingredients and stir with wooden spoon or rubber spatula just to the point where the dry ingredients have been fully incorporated.
Transfer mixture to prepared pan and spread evenly so the surface is flat throughout. Sprinkle additional rolled oats on surface.
Bake for 45 minutes or until loaf is a deep brown and a toothpick can be inserted and comes out clean.
Remove from the oven and leave to rest for a few minutes, then remove from pan and transfer to a wire rack and let cool for at least 30 minutes before slicing.
