Birthday cake magic shell: where your ice cream turns into cake!

I loved magic shell when I was a kid. It ranked up there among the most magical of things, like unicorns, rainbows, and shopping mall cookies. My mom would dish me out some ice cream and I’d douse it with chocolate magic shell and then wait for the magic to happen.

How did it harden into a shell? It was like a little fairy godmother lived inside the bottle and waved her magic wand and poof! my ice cream was covered with hard chocolate. Then I’d carefully eat all the ice cream, leaving the best part for last: the shell. If I concentrate I can still hear the crack from my spoon against the hardened chocolate.

Guess what? You can make magic shell at home. DIY homemade magic in a bottle. And it’s so easy it’ll make you cry just a little bit.

The secret behind how magic shell hardens? Vegetable or Coconut Oil.

{Kind of takes away the magic, doesn’t it? Like…that’s it? No fairy dust? No magic wands?}

The real secret is in the ratio of chocolate to oil. Add too little and it’ll still harden up in the jar. Add too much and it just tastes like, well, oil.

Traditionally, coconut oil is used in the making of homemade magic shell.  I used vegetable oil for this recipe because not all coconut oils are created equal. The brand I have in my kitchen currently stays solid unless I heat it in the microwave. (Even a super hot day doesn’t liquify it.) When I combined it with the white chocolate, it just hardened back up and stayed that way. That’s not magic shell…that’s just flavored white chocolate. Good, but not what I was going for.

The vegetable oil solved that problem and made my favorite new ice cream topping possible: birthday cake magic shell!

I love regular chocolate topping on my ice cream but, if you know me at all, you know I want everything to taste like cake…even coffee. Last month at BlogHer Food, one of the parties had an ice cream bar. You know the kind: pick an ice cream, layer on the toppings. It was fun watching the other women act like kids in a fro-yo shop. I know I piled on more than I would have if I was with my daughter, that’s for sure. 🙂

One of the toppings they had was, you guessed it, Birthday Cake Magic Shell. I’d never seen it before (and it’s not even on the website) and I was instantly smitten. I mean, it’s funfettied ice cream topping. #loveatfirstsight

This recipe is super easy and it makes a lot. It’ll last awhile on your counter too, so it’s perfect to have around this summer for the hot ice cream eating days.

After melting together your white chocolate and oil, you just have to add the birthday cake. Normally, I like to use butter extract for funfetti flavored things but for this recipe you must use cake mix. All extract has water as an ingredient and water and chocolate are mortal enemies. If you add extract to melted chocolate you’ll get a gloppy mess. Cake mix is a must! Plus, think of all the flavor variations…

Add some sprinkles and life is complete.
