Yummy chocolate cake surrounding a green marshmallow flavored filling and covered in chocolate ganache makes theses Harry Potter Cauldron Cakes the perfect, sweet treat!
Now if you really want to go wild…like say you’re throwing a Harry Potter Halloween Party and you want something a little more Cauldron Cake style, so keep reading.
I am so excited to share these homemade ding dongs with you today!! I first made these cauldron cakes back when the first Harry Potter movies started coming out. Since I do not have access to Honeydukes Sweetshop, I had to get creative!
There are no images of them in the Harry Potter books or movies, but I noticed that their treats always seemed to be easy to hold and eat without much fuss. Adding a handle to them equates fuss in my book, so I didn’t bother with it. That’s my story and I’m sticking with it!
The next time I made them, I decided to cut a hole in the top to fill with the yummy green filling and sprinkle with green decorative balls…or should I say bubbles? Don’t they look like little cauldron’s with a bubbling witches brew?
For an even simpler option, I have included instructions to make cauldron cake shaped ding dongs. Either way you make them they are equally delicious, and loads of party fun!
The length of this recipe may seem a bit daunting, but they are actually pretty easy to make.

How to make Harry Potter Cauldron Cakes
Preheat oven to 350° F. Spray 3 mini bundt pans with baking spray and set aside. Yes you could use regular muffin pans, but they won’t be as cute or have the rounded cauldron shape.
Add 1 tablespoon of espresso powder to water and set aside to dissolve.
In a large bowl, beat together eggs, oil, and sugar.
Add the espresso, water and vanilla and beat until well combined.
Stir in the flour, cocoa powder, pudding mix, baking powder, baking soda, and salt. Beat until well combined…..
Fill prepared pans about half-full with batter.
And bake for 18 to 20 minutes.
Allow to cool in the pan for 5 minutes. They will shrink up and start to pull away from the sides.
Flip cupcakes out onto a wire cooling rack and cool completely.
While cupcakes are cooling, prepare the Chocolate Ganache. Place chocolate, cream, and butter in a large bowl.
Place in the microwave and heat on HIGH for 1 minute. Stir and continue heating and stirring in 15 second intervals until smooth and completely melted.
Dip each cupcake in the ganache one at a time and place on wire rack lined with parchment paper/silicone liner to set.
When the chocolate has set, make the Buttercream Filling. Beat shortening and butter together in a large bowl.
Add the meringue powder, salt, LorAnn Oils Marshmallow Flavor, green coloring, and powdered sugar. Beat until light and fluffy, adding water as needed to achieve desired consistency.
To fill the ding dongs – use a long, thin tip to fill cupcake from the bottom.
Use a sheet of wax paper to keep the chocolate ganache from melting in your hand.
To fill the cauldron cakes – chose a large decorative tip.
Use a cupcake corer or apple corer to remove the center of each cupcake. Be careful not to push the corer all the way through.
Insert decorative tip into the cavity and fill with frosting, allowing it to ooze over the top. Decorate with decorative green ball candies.
Wands at the ready…..Accio Cupcake! Repeat as many times as necessary!
Update: The Universal Studio Wizarding World of Harry Potter is now selling their version of cauldron cakes. They are made in silicone cauldrons, that cannot be purchased, and topped with frosting that looks like flames. My brain obviously went in a different direction, but I still love them and wouldn’t change a thing!
Why not use marshmallow fluff?
I am not personally a fan of marshmallow fluff/cream. It’s extra sweet and contains high fructose corn syrup, so I generally avoid it.
I added the marshmallow flavoring to give it an unexpected flavor, not just boring vanilla. I was also dying to try out the marshmallow flavoring that LorAnn Oils sent me, and it worked perfectly!

Homemade Ding Dongs — awesome! I know these would taste way better than the original too.
Yes they do Marcie, they don’t taste like plastic,lol. Ding Dongs were my favorite when I was a kid, back when they were in foil wrappers!! They ruined them for me. 😉
These could possibly be my favorite of all your recipes – they look terrific. The “bubbles” really make them look like cauldrons. Any child in your life is very lucky:)
Awe, thank you so much Seana!
These look delicious, Lisa. I’ve never made homemade ding-dongs. This could be dangerous!
As always, I’m so impressed by the creativity and intricacy of your recipes! You make everything so unique and special, and these homemade ding dongs are no exception!!
These look so fun. Isn’t Halloween a fun time to cook. Thanks for sharing.
