Put the can of frozen lemonade (still frozen) in a blender. Fill the empty can halfway with bourbon and then add honey to fill completely (no need to be super precise). Pulse a few times to combine. Add ice to fill the blender. Blend until the ice is fully crushed. Taste and add some more honey or sugar if you'd like it to be more sweet.
Serve in small glasses with lemon slices as garnish.
