Heat the oven to 400 degrees F.
Wrap one piece of bacon around each prune and secure bacon with a toothpick.
Arrange prunes, bacon seam down and 1 inch apart, in a baking pan.
Bake 5 minutes, then turn prunes over with tongs and bake until bacon is crispy to your taste, 5 to 6 minutes more. Drain on a paper towel. Serve on a platter.
