Spray a small loaf pan with cooking spray. In a large bowl or measuring cup, combine cherry Jell-O with boiling water and whisk to combine. Let sit 2 minutes, then whisk in ½ cup vodka. Set aside.
In another large bowl or measuring cup, combine 1 cup vodka and gelatin and let sit 2 minutes. Add water and stir until gelatin dissolves completely. Pour in sweetened condensed milk and whisk to combine.
Pour half of the red mixture, about 1 cup into loaf pan. Freeze 20 minutes until firm and add 1 cup of the white mixture. Repeat twice more, letting firm 20 minutes between each addition until you have four layers, then refrigerate for 4 hours or overnight. Remove from loaf pan and cut into squares. Top with crushed candy canes and serve.
