With its customizable flavors and vibrant colors, this recipe is a hit for parties, potlucks, or after-school snacks. Cut them into playful shapes or classic cubes to suit any occasion.

In a large heatproof bowl, combine the unflavored gelatin packets and the flavored gelatin powders.
Pour 4 cups of boiling water into the bowl and whisk until all the gelatin powders have completely dissolved. This should take about 2-3 minutes.
Once the mixture is smooth and free of lumps, carefully pour it into a 9x13-inch glass or metal baking dish.
Let the gelatin cool at room temperature for about 10-15 minutes, then transfer the dish to the refrigerator.
Allow the mixture to chill in the refrigerator for at least 3 hours, or until it is completely set and firm to the touch.
Once set, use a sharp knife to cut the gelatin into 1-inch squares (or any other shape of your choice). Carefully lift the pieces out of the dish using a spatula or your fingers.
Serve the Knox Blox immediately, or store them in an airtight container in the refrigerator for up to 5 days.
