Step 1 Preheat the oven to 350 degrees. Spray a 9×5-inch loaf pan with cooking spray.
Step 2 Sift flour, sugar, and rosemary together into a large mixing bowl. Pour in beer; stir to combine. Stir in apple and Cheddar cheese until well combined; batter will be stiff and sticky. Scoop batter into the prepared loaf pan.
Step 3 Bake in the preheated oven until top is golden brown, 55 to 60 minutes. Remove from oven and pour melted butter on top. Return to oven and bake for another 3 to 5 minutes more.
Tip: Especially good with soup or chili. Try using an apple ale instead of the beer.
