The Ultimate Harry Potter Cauldron Cake – at home!

Today, we’re whisking you away to the magical corridors of The Wizarding World of Harry Potter in Orlando, Florida, to recreate a spellbinding treat – Cauldron Cakes! These aren’t just any cakes; they’re every 11-year-olds sugary dream found at HoneyDukes in Hogsmeade and SugarPlums in Diagon Alley.

Imagine a thin layer of dense, fudgy chocolate cake, topped with a THICC layer of frosting colored to look like flames. Each cake is presented in a vibrant orange box complete with DIY instructions, and the best part? The silicone cauldron that houses this delectable treat is reusable and oven-safe. If you’re a Harry Potter aficionado, a frosting fan, or just in it for the adorable cauldron, these cakes are a 5/5 must-try.

In this realm of enchantment, some links might add a commission to my cauldron, at no extra cost to you! Rest assured, we only recommend products we have tested!

  • Silicone Cauldron Molds: These come with your cauldron cakes in the parks! Do NOT throw them away! I haven’t been able to find a good silicone mold elsewhere, especially for the price.
  • Bosh Universal Plus Mixer: To whip up that perfect frosting! This mixer is also perfect for cookies, cakes, and most importantly . . . bread!
  • Mixing Bowls: For sifting and mixing ingredients: these bowls can also be used if you don’t want to use a stand mixer, or do not have a stand mixer.
  • Piping Bags and Tips: For that intricate flame-like frosting design! While you technically can use a zip lock bag, I’ve had too many of those burst on me before. A piping bag and a 1M tip will give you the perfect look, AND not create a mess! This kit is great for starters!

Instructions:

  1. Prep Your Cauldrons: Preheat your oven to 350°F (175°C) and lightly spray your silicone cauldrons with cooking spray.
  2. Cream Together Butter and Sugar: In the bowl of a stand mixer with the whisk attachment, cream together the butter and sugar until light and fluffy.
  3. Beat in Eggs: Crack the eggs into a separate bowl (to make sure they are all good), then add them one at a time to the butter and sugar mixture, mixing thoroughly between each addition.
  4. Add the Secret Ingredients: Add the mayo and the sourdough discard into the egg mixture until thoroughly combined. These will add both texture and moisture into your cauldron cakes!
  5. Mix the Wet & Sift the Dry: Mix together the Milk, Vanilla, and Pero Drink Mix Powder. Then, in a separate bowl, sift together the flour, cocoa powder, baking powder, and baking soda.
  6. Alternate Additions: Alternate adding the wet ingredients and the dry ingredients to the batter until everything is thoroughly combined.
  7. Add Chocolate Chunks: Finally, mix in 4 oz of chocolate chunks to the batter and pour 3/4 cup batter into each silicone cauldron.
  8. Bake: Bake on a sheet tray for 20-25 minutes, until a toothpick comes out with just a few wet crumbs on it (not liquid-y batter, and not entirely clean either)
  9. Decorate & Serve: Decorate with your favorite frosting recipe (or try our recipe for Classic American Buttercream).
