Ghoulishly Glowing Cupcakes - Recipe Snobs (2024)

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!!


Ghoulishly Glowing Cupcakes

• 1 black light
• 24 prepared and cooled cupcakes

White Glow In The Dark Frosting

• 7 cups confectioners’ sugar
• 1 cup vegetable shortening
• 1 teaspoon clear vanilla extract
• 5 tablespoons tonic water {diet tonic water works too}
• mini chocolate chips morsels

Extras Needed for Green Glowing Frosting

Prepare desired cupcakes and allow to cool. Begin frosting by adding confectioners’ sugar, shortening, vanilla, and 3 tablespoons tonic water into a large bowl. Beat on low speed until no loss sugar is visible. Add remaining two tablespoons as needed to bring frosting to piping consistency. Mix at high speed for about a minute to allow frosting to become light and fluffy. Place half of white frosting into a separate bowl and set aside. Add neon food coloring to frosting until it reaches desired color {orange for orange gelatin, green for lime gelatin}.

Pipe colored frosting onto cooled cupcakes and place in the freezer for at least an hour. Meanwhile pipe white frosting on half of the cupcakes using a large round frosting tip. Add two mini chocolate chip morsels for the ghost’s eyes to finish ghost cupcakes.

{Make enough frosting for about 24 cupcakes}
