Harry Potter’s Birthday Cake Recipe

Harry Potter's Birthday cake

You’re a wizard, Harry!” I wish someone would tell me “You’re a witch, Marie“, but oh well, we can always dream. Still waiting for my letter though. Not losing hope. And getting into baking Harry Potter goodies while I wait. So I know, Harry Potter’s birthday was some time ago already but I could not help myself and try to bake Harry Potter’s birthday cake!

Happee Birthdae Harry.

And now it is your turn to try and bake it. Because, as it turns out, it is so easily made and so delicious as well! Perfect with a cup of tea, with only a thin layer of frosting, and just yummy!

-225g softened butter

-225g sugar

-4 eggs

-2 tsp baking powder

-50g cocoa powder

-150g softened butter

-330g icing sugar

-1/2 tsp vanilla extract

-2 tbsp milk

-Pink and green coloring


1. For the chocolate sponge. Pre-heat your oven at 180°C.

2. Put the softened butter in a salad bowl and beat with an electric whip.

3. Add one by one and little by little, sugar, eggs, flour, baking powder and cocoa powder. Beat until fully incorporated.

4. Butter and flour two cake tins. Lin with parchment papers. Divide mixture equally between both tins. Put into the oven for 25 minutes.

8. Cover the top of the first sponge with a thin layer of frosting. Put the other sponge atop. Cover the cake with pink frosting. Let set in the fridge for a few minutes.

9. Add a few drops of green coloring to the remaining buttercream. Beat until fully colored. Pur green frosting into a piping bag.

10. Use a toothpick to draw the latter on the pink frosting to use as template. Remove cake from the fridge. Pipe the letters on the cake.

11. Cut yourself a slice, pur yourself a cup of tea and enjoy!

    I am a huge Harry Potter fan! I even used it as the primary text for my dissertation because I enjoy it so much and it made my last year at university more fun as I spent a year analysing my favourite books. But despite listening to the audiobook more times than I can count and watching the films numerous times, I have never attempted to recreate any of the food featured in the series! But this is something I certainly want to try now after seeing your own attempt at Harry’s birthday cake! Which by the way looks fantastic and it makes me crave some cake right now!

    I’m not a Harry Potter fan but I’m a chocolate cake fan! I just like how simple this recipe is, I’ll buy some ingredients to make cake the next time I’m at the market.

    OK this is absolutely wonderful! It looks so cool and just like in the film, and it sounds delicious.
