Using an electric mixer, beat the cream, condensed milk, and vanilla in a large bowl on medium-high until stiff peaks form, 3 to 4 minutes. Gently fold in the peanut butter followed by the bananas and crumbled bacon.
Spoon the cream mixture into a 4 1/2- by 8 1/2-inch loaf pan or 1 1/2-quart freezer-safe container. Spoon half the "add- ins" on top. Freeze until set, at least 4 hours. Once set, cover with plastic wrap and freeze for up to 2 weeks.
