Preheat oven to 350.
In a large bowl stir together the flour, baking powder, baking soda, and sugar. Add the beer, stir until just combined.
Spray a loaf pan with cooking spray. Pour that batter into the pan in an even layer. Pour the melted butter over the loaf.
Bake for 40 minutes or until cooked through. Remove from oven, allow to cool completely before slicing, chill if necessary.
In a food processor add the cream cheese, cheddar, IPA, sriracha, cornstarch and salt, blend until smooth.
Slice the bread into 8 slices.
Butter one side of each slice.
Heat a non-stick pan over medium high heat.
Working in batches, place one slice of bread, buttered side down in the pan. Spread with about ¼ cup of the cheese mixture, then a slice of bacon, then another slice of bread, buttered side up.
Cook until the bottom bread is slightly browned, then gently flip. Cook on the other side until the bread is golden brown. Serve warm.
