Harry Potter Birthday Cake | Hogwarts Letter Cake | My Harry Potter Kitchen II (Recipe #2)

Hello Witches and Wizards!

Welcome back to another week in our foodie adventure through the Wizarding World as we create some more magical recipes from Harry Potter!


If you're new to My Harry Potter Kitchen... hello! This is the YouTube series where I'm baking my way through the Harry Potter books coming up with magical recipes for every item of food and drink that we find. I upload each brand new recipe to my YouTube channel before posting the recipe here so be sure to subscribe on YouTube to be the first to see what's next!


This week we're back to Harry Potter and the Chamber of Secrets as we celebrate Harry Potter's birthday!

Not long after last week's recipe from the Chamber of Secrets, our second recipe is a few paragraphs down in Chapter One 'The Worst Birthday':

"Of course, his hopes hadn't been high, they'd never given him a proper present, let alone a cake"

One of the most iconic Harry Potter recipes is the birthday cake he receives from Hagrid in the Philosopher's stone - which we recreated during our recipes from the Philosopher's Stone. But seeing as it's a new year at Hogwarts - I thought we'd take things up a notch with Harry Potter's Birthday Cake 2.0.

For this week's recipe, we're going to create a birthday cake and decorate it as the one thing that Harry is really wishing for at this point in the book - some letters from his friends!


Our Harry Potter Birthday Cake 2.0 is going to be made from a red and white marble sponge with red and white buttercream as a nod to his Gryffindor heart. We're then going to decorate the entire cake with fondant to transform it into the pile of letters which for some odd reason haven't arrived - more on that later in the book...

This is a super easy cake recipe, and although the cake decorating techniques take a little bit of practice, letters come in all shapes and sizes so even if it's not 'perfect' it'll still be pretty realistic - just blame it on the owls!

Harry Potter's Birthday Cake | Hogwarts Letter Cake Ingredients

(serves 12-16)


Ingredients:

for the Gryffindor marble sponge cake

  • 20oz (550g) butter

  • 20oz (550g) golden caster sugar

  • 10 eggs

  • 20oz (550g) self-raising flour

  • 1 tbsp vanilla extract

  • 1/2 tbsp mixed spice

for the vanilla buttercream filling

  • 10oz (275g) butter

  • 20oz (550g) icing sugar

  • 1 tbsp vanilla extract

  • 2 tbsp milk

  • red food colouring gel

for the green royal icing

  • 2 egg whites

  • 350g icing sugar

  • 1-2 tsp lemon juice

  • green food colouring gel

to decorate

  • 500g white fondant icing

  • yellow and red food colouring gel

  • 1 tbsp raspberry jam

  • cocoa powder

Method:


  1. To begin you'll want to prepare your sponge by creaming together the butter and sugar until light and fluffy.

  2. Scrape down the sides of the bowl and continue beating in your eggs one at a time. (Wizard tip! Add in a spoonful of flour with each egg to prevent the mixture from curdling- this will ensure it rises correctly in the oven)

  3. Add in the rest of the flour, vanilla and mixed spice and then mix through until well combined

  4. Take 1/3 of the mixture out into a separate bowl and add in your red food colouring stirring through until you have an even, vibrant red colour

  5. Grease and line a 20cm square baking tin and then add in your red and white cake batter a spoonful as a time in different spots around the tin. Gently tap the tin on the counter to even it out and then take a skewer and marble the batter together (Wizard tip! Don't over mix it as the two will continue to marble as it's baking)

  6. Bake the cake in the oven at 180 C (350F) for 40 minutes until golden. A skewer should come out clean when inserted into the middle

  7. For the buttercream whisk the room temperature butter until smooth and then add in the icing sugar a third at a time. Whisk through with each addition until it is well incorporated.

  8. Flavour the buttercream with vanilla and milk, scrape down the sides and continue whisking for another minute until light and fluffy

  9. Split the icing into two and then dye half of the buttercream red. Place the white and red buttercream into separate piping bags and leave to the side until you're ready to decorate.

  10. Level off the top of your cake so it's nice and flat. Create a stencil for your letters and then use it to cut out your sponge. Cut your sponge horizontally so you have two layers to sandwich together

  11. Use the white buttercream to pipe a border around the first layer of cake and then alternate with red and white buttercream as your pipe along the middle. (Wizard tip! Pipe diagonally so you get the stripe effect no matter how big your cake slice is).

  12. Sandwich the next layer of cake on top and then carve the sponges down so you have three levels to your letters, giving it a 3D effect. Use some more white buttercream icing to crumb coat the whole cake making sure you don't lose the definition from your carving. Place in the fridge for an hour to set.

  13. Use yellow food colouring to achieve an 'off-white' envelope colour, kneading it into your fondant and then let it sit to one side so the colour settles. Repeat the process with some red for our wax seal

  14. Place some icing sugar onto your surface and then roll out your white fondant to 1/2cm thick. Use the rolling pin to help lift the icing over the cake and then smooth the fondant over the top and sides. Trim the edges and then use a fondant smoother to square off the sides and emphasise the definition of the letters. Place in the fridge to set for at least 30 minutes

  15. Roughly roll out the red fondant and then use a Hogwarts stamp cookie cutter to press into the middle. Pinch the edges with your fingers to get a 'wax drip' effect

  16. For the royal icing, pasteurise the egg whites in a bowl over hot water while whisking then place into your mixing bowl whipping until light and frothy. Add in your icing sugar a spoonful at a time. Once the mixture leaves a trail that doesn't disappear for around 10 seconds it's ready to go. Add in your green food colouring and whisk through. Place into a piping bag with a writing tip

  17. Thin your jam with some hot water and then brush over your wax stamp to give it a shiny, melted look. Then using some cocoa powder dab the cake, and blend in to give it an aged letter look. You can then add in any other fondant indentations to the cake.

  18. Practice piping your letters on some baking paper and then when you're confident pipe the address on top of the letters. Finish the cake with your spare red buttercream piping around the border of the cake and your cake board

Harry might be missing his friends but this Hogwarts Letter Cake for Harry Potter's Birthday is sure to remind him of home (his real home in the Wizarding World that is!)
