Preheat oven to 350 degrees. Spray mini muffin pans with cooking spray.
Stir together oil and sugar. Stir in vanilla, cocoa, and eggs. Slowly stir in salt and flour.
Scoop 1 tablespoon of batter into each muffin cavity. Bake 8-10 minutes, until a toothpick comes out with just a few crumbs stuck to it.
Immediately upon removing from oven, top with a Candy Cane Hershey’s Kiss (or your favorite Kiss flavor). Do not move your trays until the Kisses have completely hardened. The flavored Kisses are less stable than the regular chocolate ones, so there is a chance some of them will fall slightly, but if you touch the trays they will certainly all fall!
Use the tip of a knife to help you removed cooled bites from pans.
