Homemade Option
Want to Make It From Scratch?
Prefer not to use a box mix? You can absolutely go homemade! Try this rich chocolate cake base:
- 1 1/4 cups all-purpose flour
- 1/2 cup Dutch-process cocoa powder
- 1 tsp baking soda
- 1/2 tsp salt
- 1/2 cup vegetable oil
- 1 cup buttermilk
- 1 tsp vanilla extract
- 1 egg + 1 egg yolk
- 3/4 cup brown sugar + 1/4 cup white sugar
Bake in two 8-inch pans at 350°F for 22–25 minutes. The cake will be moist, slightly fudgy, and perfect for the vibrant pink frosting.
How to Make Harry Potter Birthday Cake
Follow these simple steps to recreate Hagrid’s iconic cake:
- Bake the Cake:
- Prepare two 8-inch round cakes according to your recipe or box instructions.
- Let them cool completely before decorating.
- Prepare the Frosting:
- Color your buttercream a bright pink using food coloring.
- Layer it up, smear on the pink frosting, and let the magic begin. This isn’t a cake for perfectionists — it’s a cake with heart.
- Decorate with Green Icing:
- Fill a piping bag or zip-top bag with green decorating gel.
- Write “HAPPEE BIRTHDAE HARRY” just like Hagrid did, charming misspellings and all!
- Final Touches:
- Embrace imperfections! Sloppy writing and uneven frosting only make it more authentic.
Tips to Perfect It
- Use Gel Coloring: It gives a more vivid pink and green without watering down your frosting.
- Chill Your Cake: A brief 30-minute chill helps firm up the frosting for easier writing.
- Don’t stress about the piping. Hagrid’s original cake was adorably wonky, and that’s the whole point — imperfections make it perfect.
Butterbeer Frosting Twist (New Optional Section)
Add a Magical Flavor Boost: Butterbeer Frosting
If you’re a true Potterhead, you know that no wizarding party is complete without butterbeer. Here’s how to give your frosting that signature flavor:
Butterbeer Frosting Ingredients:
- 1/2 cup butterscotch chips (melted and cooled slightly)
- 1/2 tsp butter extract
- 1 tsp vanilla extract
- Your usual buttercream base (butter, powdered sugar, milk)
Whip it all together for a sweet, buttery flavor with hints of caramel — a perfect companion to the chocolate cake.
