D&D DIY: Gelatinous Cubes
Tara Theoharis

There's more to good gaming than the game itself; there's also the "dungeon dressing" involved in hosting a session. For the following article, we turn to The Geeky Hostess (aka, Tara Theoharis) who offers advice and suggestions on how to best do so.

I t's your turn to bring a snack to your regular D&D session, and you're tired of the same ol' Doritos and M&Ms. If you have at least 4 hours before the session starts, I've got you covered. Bring some delicious and on-theme Gelatinous Cubes!

What sets these apart from any other green JELLO? It's made with the nectar of the D&D gods: Mountain Dew. Caffeinated and a little bubbly? You can't go wrong!

Just get yourself a 6 oz. packet of Lime JELLO (or two 3 oz. packets), 2 cups of Mountain Dew, and any items you may want floating in your gelatinous cubes.


  1. Mix your packet(s) of JELLO with two cups of boiling water into a deep, square baking dish. Stir 2 minutes until completely dissolved.

  2. Stir in two cups of chilled Mountain Dew. Measure slowly and carefully so the carbonation has time to die down a bit and give you an accurate measurement!

  3. Cover the dish and move it into the refrigerator. Let chill for two hours.

  4. If you plan on putting any items into the JELLO, make sure they are clean/sanitized. I suggest plastic figurines, plastic gold pieces, or small candies.

  5. Carefully uncover the dish (ideally without moving it) and place the objects in.

  6. Let chill for 2 more hours or until firm.

  7. Using a sharp, non-serrated knife, cut the JELLO into squares. Serve!

DM's Corner

Want to incorporate the cubes into your game? Try some of these ideas!

  • Have a laminated game mat? Place the cubes straight onto the mat when the players encounter them. Bonus points for cutting the cube to scale!

  • Place treasure inside of a cube and see which player is brave/stupid enough to try to get it!

  • Did your last session end with someone inside of a gelatinous cube? Steal their figurine and put it inside the JELLO for the start of your next session.
