Method

  1. Preheat the oven to 350F/180C.
  2. Lightly grease two tins or alternatively line with baking paper.
  3. For the cake batter, combine the butter and sugar until fluffy. Then, add eggs and mix. Finally, add in the vanilla, salt, baking powder and flour. Mix until smooth.
  4. Divide the mixture between the two pans and bake for 35-40 minutes or until a toothpick comes out clean.
  5. While the cakes are cooling, make some buttercream by mixing butter, icing sugar and vanilla.
  6. Spread jam followed by the buttercream on top of one of the cakes. Then, sandwich your two cakes together.
  7. To prep decorating, place your cake on a decorating wheel and trim the top making it level. Cover the cake with the remaining buttercream. Roll out white icing a couple of inches wider than your cake. Carefully place this over your cake, smooth the icing from top to bottom and trim any excess.

Top Tip: To show extra loyalty to your child's favourite house, divide your cake batter in two and add into each a colour of your chosen house before pouring into tins and baking. When you cut your Harry Potter cake, you should see the house colours.

Let's Decorate!

The Harry Potter world has endless inspiration for magical Harry potter cake ideas. This list has a few Harry Potter birthday cake decoration ideas we love for a general Potter cake, but you can also use similar methods to create other parts of the Harry Potter universe.

Scarf

Take the two colours of your child's favourite house and alternating between each colour, lay flattened pieces horizontally to create the scarves stripes. You can drape this across the cake and add some fringing on the ends for a realistic effect. You could also wrap the scarf around the cake. We recommend placing the scarf first as it can be one of the bigger pieces and makes a great backdrop for other decorations.

Harry Potter Glasses

Get some black fondant and roll it out. Use a cookie cutter to cut out two circles, then, using a fondant tool cut out the inside circles. Roll out more black fondant to make the arms, bending the end of each arm. Assemble the glasses with one arm crossing over the other, cut off any excess and glue to secure your creation.

To make the famous Harry Potter scar roll out some black fondant and carve a lightning bolt.

Golden Snitch

Roll some white fondant into a ball and cover with gold dust. Roll out another ball of white fondant and cut out wings. Use a fondant picker to perfect your wings before using a toothpick in each one to secure them to the ball. Finally, add gold dust to the wings.

Sorting hat

Get a small ball of brown fondant and sculpt it into a teardrop shape. Flatten the bottom perimeter against the surface below to create the brim of the hat. Use fondant tools to create the face and to give a realistic worn look to the hat.

Harry Potter's Wand

Roll out a ball of brown fondant into a long cylinder, and keep it straight with a skewer. Make the wand's details with extra brown fondant. You don't have to stick to making the wand of Harry Potter. You can make the wand of your favourite character, just search an image of their wand and imitate it using fondant.

Broomstick

To make the stick, get dark brown fondant and roll it to a long cylinder. For the bristles, use a lighter brown fondant and mould into a teardrop. Glue these together to form a broom. Use fondant tools to score tiny lines into the teardrop to make individual bristles. Use a tiny bit of gold or yellow fondant and wrap around the joint between the stick and the bristles.

Alternatives

Other fun and fantastic ideas include a quidditch cake, a house-themed cake, a Hedwig cake or a Hogwarts cake. Just get some fondant and sculpt a Harry Potter cake topper!

Good To Know

  • Cakes are good for several days at room temperature in an airtight container. If you want to refrigerate the cake, wrap it in plastic.
  • For a dairy-free cake, substitute the eggs for applesauce or mashed banana. Instead of butter try coconut oil.
  • For a gluten-free cake try almond, buckwheat, quinoa or coconut flour.
  • Kids of all ages can enjoy helping with the baking. Younger children (2-5 years) can help stirring or play with ingredients, whilst older children can help to measure ingredients, following the recipe and making decorations.
  • This cake is suitable for all including babies over one year old.
