On Harry’s 11th birthday, Hagrid gives him a birthday cake and his Hogwarts letter. Recreate the moment with homemade cake for Harry’s birthday.Jump to Recipe
On July 31, 1991, Hagrid showed up to the hut that Uncle Vernon was trying to hide from the wizarding world in. Harry Potter found out that he was a wizard and would be going to Hogwarts. Harry received a birthday cake from Hagrid. The cake was the first he’d been given since he was a year old.
“Anyway – Harry,” said the giant, turning his back on the Dursleys, “a very happy birthday to yeh. Got summat fer yeh here – I mighta sat on it at some point, but it’ll taste all right.”
From an inside pocket of his black overcoat he pulled a slightly squashed box. Harry opened it with trembling fingers. Inside was a large, sticky chocolate cake with Happy Birthday Harry written on it in green icing.
-Harry Potter and the Sorcerer’s Stone
This cake was one of the first recipes that I made for our Harry Potter Club. I’ve had a recipe for a chocolate cake for a long time. I used that as my base for the cake. Then I made my favorite cream cheese icing and tinted it pink. The book doesn’t describe the color of the icing on the cake, just the letters. So, I went with the movie version of this cake for design but book for the words.
In the movie, Hagrid spells the words wrong, but not in the book. Luckily, I had some green icing meant for writing on cakes leftover from one of the boys birthday parties. It worked much better than trying to pipe it myself as I did on Nick’s Deathday Cake.
For Harry’s Birthday Cake, I decided to make it a double-layered cake with a bit of frosting in the middle. I posted my chocolate cake recipe a long time ago (you can find it here), but I’ll quickly go over the steps again. You don’t have to make a cake from scratch for this, but since I love to bake, I did. A box chocolate cake would work just as well.
Step by Step
Preheat the oven to 350F then grease and flour two 8- or 9-inch round cake pans.
Combine 2 cups of flour, 1 1/3 cups of sugar, 1 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp of salt in a large mixing bowl.
Add 1/2 cup of butter, 1 cup of milk, and 1 tsp of vanilla extract. Mix this with an electric mixer for about one minute.
Then add 2 eggs and 2 oz of melted semisweet chocolate. Mix this on high speed for a minute or two, until it forms a batter.
Divide the batter into the two prepared cake pans. Bake for about 30-45 minutes until a toothpick comes out clean. Cool for 10 minutes in the pan, then transfer to a cooling rack.
While the cake cools, make your frosting. Combine 4 oz of softened butter with 4 oz of softened cream cheese until they are well mixed. Then add 2 cups of powdered sugar, a little at a time, until the frosting is creamy and smooth.
Stir in 1 tsp of vanilla extract, then a drop or two of red food coloring to make it pink.
Wait until the cakes have completely cooled. Put a small amount of frosting on top of one cake. If the cake isn’t flat on top, it helps to use a bread knife to cut the top off.
Then stack the other cake on top of the frosting to hold them together and form a line of frosting in the middle.
Add the rest of the pink frosting to the cake, spreading it out to cover the entire top and sides of the cake. I find having an angled icing spatula works wonders for frosting a cake. Angled spatulas are flat enough to smooth out the frosting.
Once you have your cake covered with the pink frosting, you may want to give it a few minutes to set. Then use green writing gel to put the words on the cake. You can go book-style and write “Happy Birthday Harry” or movie-style and spell it “Happee Birthdae Harry.”
And the wonderful thing about making this cake from Hagrid is that he is not well-known for his cooking and baking skills. So if the words don’t line up well or get larger and smaller, then you can claim it’s just Hagrid’s attempt at baking!

The cake is so yummy. I’ve used this recipe for many cakes before making the Harry Potter one.

Who could ever forget that scene of the cake Harry gets in the movie! Love that you have recreated this as it is sure to be a hit for children everywhere. Your recipe is set out in such an easy to follow way, that I am looking forward to giving this a go.
It’s such a pivotal moment for so many reasons, so it was great to be able to reenact in a small way with the cake.
You are so creative! Love the way you made Harry Potter’s cake. Looks delicious. I’m a Harry Potter big fan, I’ll make this recipe for my birthday
It’s such a yummy cake recipe. And of course, it’s always better if it’s Harry Potter themed!
What a fun idea! I can’t wait until my youngest is old enough for Harry Potter so I can experience it all over again!
We recently started reading the illustrated versions of the book with my oldest son. He was 5 when we started but he’s 6 now and we are about 1/3 of the way through Chamber of Secrets. My youngest can’t wait until he is 5 so we can start reading the books to him, too. My husband had also never read the books (only watched the movies) so it’s new for both of them which is so fun.
Love this idea of a cake. My cousin is Harry Potter fan. I am sure she would love a cake like this. I will try out your recipe and surprise her with a cake.
That sounds like the perfect surprise for any Harry Potter fan!
That was an amazing idea. We love Harry Potter! As for the recipe, I’m really not that much of a baker but this looks simple enough. And yummy, too
It’s a pretty easy cake to make. Of course, you could do a boxed cake and decorate it the same, but we like to cook from scratch most of the time.
The idea is great! Love it!!! And most importantly, the recipe is very straightforward, it is not that difficult to make. Thanks a lot.
It’s a delicious cake recipe and one we’ve made for many occasions.
My kids grew up with the Harry Potter series and read all the books and saw all the films. It was an exhilarating time with that cake scene being one of the memories they hold dear. Kudos on your creative approach
I can’t even tell you how many time’s I’ve read the entire series and watched the movies. We also listen to the soundtracks a lot. My boys are just starting to read the books with us and it’s so fun to go through that first experience with them.
My son is a huge Harry Potter fan! He has a wand from that very same place, such a special experience! Love this cake too, sounds delicious and I can’t wait to make one!!
We have a few wands, my youngest son’s room is the Gryffindor Common Room so they are all hanging in there. I bet your son would love to make this cake with you!
This Harry Potter Birthday cake looks delicious. My daughter is a big fan and we will try the recipe soon.
It’s such a fun recipe to make for any Harry Potter fan. The cake is the perfect balance of sweet but not too sweet, so even a non-HP fan would still enjoy it!
It’s a really interesting way to prepare a birthday cake. Hope, it will help me in the future. By the way, thanks for writing such an informative post.
It’s fun to recreate things from our favorite books/movies. A perfect birthday cake for any Harry Potter fans you know.
