Heat the oven to 350° F. Crisp the bacon in a skillet. When the bacon is cooked, drain it on paper towels and pour 3 tablespoons of bacon fat into a loaf pan. This bread is not for the faint of heart.
Roughly chop the bacon. Remove the stems and seeds from the jalapeños and roughly chop them.
Put the flour into a mixing bowl. Mix in the cheddar cheese. Now make a well in the middle and pour in the maple syrup and the beer. Mix together until everything is moistened and combined (a few lumps are okay).
Break the cream cheese into small chunks and drop them into the dough. Add the jalapeños and bacon and fold them in until everything is uniformly mixed. Now scoop the dough into the loaf pan and spread it evenly. Pour the melted butter on top and put the pan on a baking sheet and into the oven. Set the time for 20 minutes.
At 20 minutes, sprinkle the sugar on top of the loaf, then bake the bread for another 40 minutes, or until a toothpick test comes out clean. Allow the bread to cool for about 10 minutes before turning it out of the pan.
