Equipment

Ingredients

For the Jello Cubes

  • 6 tsp. Knox Gelatin - divided
  • ½ cup Chocolat Deluxe White Chocolate Liqueur - divided
  • ½ cup Mr. Black Coffee Liqueur - divided

For the Jello Skulls

  • tsp. Knox Gelatin
  • cup Chocolat Deluxe White Chocolate Liqueur

Instructions

  • Place skull mold on a small cutting board - this will make it easy to balance as you place it in the fridge. Bloom (dissolve) 1½ tsp. Knox Gelatin in 1 tbsp. cool water in a small bowl for 30 seconds. Stirring gently.
  • Heat ¼ cup white chocolate liqueur in a small saucepan for no more than 1 minute over low/medium heat. As soon as you see any boiling bubbles, turn the heat off. Stir in bloomed gelatin until dissolved.
  • Use the dropper (that came with the skulls) to fill at least 12 skulls and place them in the fridge. You’ll have enough to fill more than 12 - it’s a good idea to fill more because some may come out imperfect. If you still have extra, simply use it in the next step.
  • Place cube molds on a small cutting board for easy placement in the fridge. Bloom another 1½ tsp. Knox Gelatin in 1 tbsp. cool water. Heat ¼ cup white chocolate liqueur in a small saucepan for no more than 1 minute over low/medium heat. As soon as you see any boiling bubbles, turn the heat off. Stir in bloomed gelatin until dissolved.
  • Spoon 1 tsp. liqueur/gelatin into each cube mold. Refrigerate for 1 hour.
  • After 1 hour, repeat step 4 with ¼ cup Mr. Black liqueur (instead of white chocolate). Spoon 1 tsp. liqueur/gelatin into each cube mold. Refrigerate for 1 hour.
  • Repeat steps for another white chocolate liqueur layer and Mr. Black layer, ensuring each layer chills for 1 full hour before adding another.
  • Carefully remove the cubes of jello. They should slide out of their molds easily. I find I can flip the cube molds entirely inside out without breaking the jello. 
  • Remove skulls from their molds. Place a skull on each cube and serve. 

Notes

If making the day before, consider the texture will get harder if refrigerated in a closed container overnight, almost like gummy bears. If making a day ahead, use only 1 tsp. gelatin per layer instead of 1½ tsp. of gelatin. This will ensure your jello isn't too firm the next day.
My cube molds hold exactly 4 tsp. of liquid, so they’re easy to measure out. If you’re using different size molds, or no molds at all, and instead, you’re using a sheet pan or Pyrex and slicing the jello into cubes, just consider the following ratio of gelatin to liqueur: For extra firm jello, use 6 packages of gelatin per 1 cup of liqueur, but you can use as few as 4 packets for more jiggly jello.
To make a non-alcoholic version, use ½ cup strong coffee and 4 tsp. sugar. Use ½ cup whole milk with 4 tsp. sugar and ½ tsp. real almond extract. You can also use vanilla extract, but most vanilla extracts are brown and will turn the milk a brownish color. Follow the recipe exactly the same, otherwise.
