Glow in the Dark Cupcakes

Sometimes it’s pretty cool to be a Rock Star Mom! I love it when the kids think what I make is cool, and let’s face it, those times are few and far between, especially with teenagers. These Glow in the Dark Cupcakes will put your kids {and adults} in awe of you, but Shhh…don’t tell them…they are really easy! 

HOW TO MAKE GLOW IN THE DARK CUPCAKES

These are perfect for your Halloween Party or even a fun family Halloween Dinner. Just remember, you will need a black light to see them glow. Black lights are available at most department stores, like Walmart, Target, Ace Hardware, etc. It’s best to buy the actual black light though, we tried the light bulb and it didn’t work as well.

How to Make Glow in the Dark Cupcakes

First you will need to frost your cupcakes. The recipe is below, but essentially it’s frosting with Tonic Water added. I found that using a star tip for decorating was best. We also tried orange frosting, but the white turned out best. After the cupcakes are frosted, pop them into the freezer while you make the jello.

And here is where most of the action happens…jello and tonic water!

How to Make Glow in the Dark Cupcakes

Mix lime jello with 1 cup boiling water and stir about 2 minutes until dissolved.

Add 1 cup tonic water to the jello. You can find tonic water near the liquor in your grocery store.

Now fill a large bowl with ice water and place the bowl of jello in. Continue to stir. You want the jello to cool down, but not begin to set up. When the jello is cool to the touch, remove it from the ice water.

Now it’s time to dip the cupcakes. Remove a couple at a time from the fridge and dip into the jello. Place them back into the freezer for 5 minutes. Repeat this dipping – freezing process 6 times. Be sure to stir the jello each time and watch it so it doesn’t start setting up. If it does get thick, dipping 4 times will work as well, but 6 is better.

Keep cupcakes in fridge or freezer until you are ready to serve them. And store leftovers in the fridge as well. You should be able to make them a day or so ahead, although the ones I made I used the same day.

  1. Could you use whipped cream frosting?

    1. Madeline from HoosierHomemade says:

      I’ve never tried it- it might fall apart in the solution, but you can definitely give it a shot!

  2. My daughter is turning 30 on the 27th of October,and I’m going to make her a Halloween cake that glows in the dark. My question is how would I get the yellow,and orange,and green to glow. I do know that white fondant and icing will glow with a black light. Will it make a difference if I use a regular black light or an florescent black light.

    1. Yes Scott, we used a UV Black Light for the cupcakes.
      Happy Baking!

  3. Can I add tonic water into a whipped cream cheese frosting without ruining it?

    1. Hi Meagan, I have not try it with whipped cream cheese frosting before. It’s certainly worth a try.
      Happy Baking!

  4. Why does it have to be real butter, my daughter is allergic. Just wondering why I can’t use the soy substitute I bake with.

    1. Hi Susan, it does not have to be real butter, whatever you substitute with in your frosting is fine. I make my frosting with real butter, not margarine or shortening.
      Happy Baking!
