Preheat the oven to 375 degrees. Cook the bacon in a medium skillet over medium-high heat until browned, about 8 minutes. Transfer to a paper-towel-lined plate with a slotted spoon. Reserve the drippings.
Crumble enough of the fruitcake to measure 1 cup; set the remaining cake aside. Mix the crumbled cake, flour and butter with your fingers in a bowl until the mixture is in pea-size pieces. Place on a baking sheet and bake until crisp, 15 to 20 minutes, stirring halfway through. Let cool, then add the bacon and crumble the mixture into smaller pieces.
Beat the gorgonzola, cream cheese, chives, Worcestershire sauce and cayenne in a bowl with a wooden spoon until smooth; set aside. Line a mini loaf pan or small souffle dish with plastic wrap, leaving a long overhang on the sides. Press the crumble into the bottom of the dish. Spread the cheese mixture over the crumble layer and fold in the excess plastic wrap to cover the cheese. Refrigerate until firm, at least 1 hour.
Meanwhile, brush a baking sheet with some of the reserved bacon drippings. Slice the remaining fruitcake into 1/4-inch-thick pieces with a serrated knife (if they fall apart, press back together with your fingers). Place the slices on the prepared baking sheet, brush with more drippings and toast 7 to 10 minutes per side. Cool on the baking sheet.
Uncover the cheese mold and invert onto a platter. Serve with the fruitcake toasts.
