Preheat oven to 375°F. Lightly grease the loaf pan and set aside.
Place flour, sugar, baking powder, salt, ground cinnamon, ground ginger, and ground nutmeg in a mixing bowl and whisk together.
In a small mixing bowl whisk together butter, pumpkin puree and egg.
Create a small well in the center of the flour mixture and add beer and pumpkin mixture. Stir together until the dough just comes together. Do not over mix! (if there are small flour pockets, gently stir them away; a couple remaining flour pockets are okay). Fold in the cheese until just combined.
Pour mixture into a prepared loaf pan and bake for about 1 hour an 15 minutes to 1 hour and 20 minutes, or until a toothpick comes out clean when inserted into the center of the loaf.
Remove loaf from pan and allow it to cool until just warm to the touch (about 1 hour and 30 minutes), before slicing.
Slice and serve with whipped butter, if desired.
