Hey Everyone!! I’m just gonna start out by saying, I am so stinking excited about this recipe! A couple of weeks ago I had a follower e-mail me about a frosting recipe that would glow in the dark. Or I should say almost glow in the dark.

Specifically she needed a cupcake recipe that could glow under a black light, but the trouble was that I couldn’t find one on the internet to try, so I decided to try my hand at making one. After a couple of tries I am glad to report that I have figured it out!! Yay! And the secret ingredient that causes it to glow is…

Tonic Water! Cool, right? The quinine in the tonic water causes it to glow under a black light for some reason. So, the challenge was to get enough if this into a frosting without making it too bitter or runny. Ugh! Turns out this was a little harder then I thought, but after trial and error I got a frosting that I loved that would actually glow, until I started adding color to it, and no matter what I did I just couldn’t get the stupid frosting to glow after I added food coloring.

Then it dawned on me that if you make gelatin with tonic water the jello will glow. What I ended up doing is taking my cupcake and frosting it. Then I stuck it in the freezer to let the frosting get nice and hard. After cooling I took the cupcake and dipped the frosting into liquid gelatin.

After a few dips and trips back into the freezer to set, the frosting glowed!! Before you start just know that the white frosting glows the best. The green, or if you decide to do orange, will glow it just isn’t as bright. Also a quick note, the darker you go with your color on the frosting the less it glows. And lastly, if you decide to make the colored frosting with the gelatin, discard any left over gelatin that you do not use for the frosting. If you want to make glow in the dark jello then use less tonic water or else it will come out way too bitter {like a 3 to 1 ratio, 3 parts water to 1 part tonic water}. Hope you all have as much fun with glowing cupcakes as me and my family have. Enjoy!!

When gelatin is cool to the touch take cupcakes out of the freezer a couple at a time. Dip into gelatin upside down, submerging the frosting but not the cake {it is ok for the gelatin to drip onto cupcake, just don’t submerge it completely}. Rotate cupcakes dipping and then returning to the freezer for about a minutes to set gelatin, then re-dip. Dip 4 to 6 times for best results.
