  • Total Time: 35 minutes
  • Yield: 6 servings

Ingredients

Scale
  • 1 box of your favorite chocolate or vanilla cake mix
  • 1 cup of vanilla frosting
  • Gel food coloring in green, purple, and black
  • Edible glitter or shimmer dust for a mystical effect
  • Mini plastic spider decorations or glow-in-the-dark accents
  • Clear 8 oz mason jars or dessert containers
  • Optional: candy eyeballs, witches’ hats, or themed sprinkles

Instructions

  1. Start by baking your cake according to the package instructions. Allow it to cool completely before assembling.
  2. Divide the vanilla frosting into bowls and add gel food coloring in vibrant Halloween hues: green, purple, and black. Mix well until desired color intensity is achieved.
  3. Add a layer of cake crumbs or small cake pieces at the bottom of each jar using a spoon or piping bag.
  4. Top with a layer of colored frosting, then repeat layers until the jar is nearly full, creating a swirling or layered effect for visual appeal.
  5. Finish with a small frosting layer on top. Sprinkle with edible glitter for shimmer and decorate with mini spiders, candy eyeballs, or themed sprinkles for a spooky touch.
  6. Store the jars in the refrigerator for up to 2 days, covered with a lid or plastic wrap. Decorate just before serving to keep the decorations fresh and vibrant.

Notes

  • Use premade cake or leftover cake for convenience and extra flavor.
  • Decorate with themed items for a more festive appearance.
  • For dietary modifications, opt for gluten-free, dairy-free, or vegan ingredients.
  • Ensure the jars are fully cooled before layering to prevent melting or smearing.
