Funfetti Birthday Cake

Funfetti Birthday Cake

Funfetti Birthday Cake is sometimes known as confetti cake, but I prefer the name funfetti because this cake really is so fun! It’s made by mixing rainbow sprinkles into the cake batter which creates the effect. Then I’ve decorated it with more sprinkles on top! It’s perfect for a party, and especially birthdays! I first made this Funfetti Birthday Cake for my birthday, which is why I’ve named it as such. It’s flavour is simple vanilla, which is that classic flavour that everyone loves.

I made the sponge by creaming together butter and caster sugar. Then I added the eggs, two at a time, and mixed between each addition. I then added vanilla extract, and finally folded in self raising flour.

Then I added sprinkles!

I divided the mixture equally between the tins and baked the cakes for 35 minutes, then I left them to cool fully.

Next I made the buttercream by mixing butter, icing sugar and vanilla extract together until smooth.

On a plate I started stacking the layers and piping buttercream between each one.

I put on the final layer of sponge and smoothed icing all over the top using a palette knife to smooth it out.

Then I piped swirls around the edge and I filled the middle with more sprinkles!

Ingredients

For the cake

  • 500 g Butter or baking spread
  • 500 g Caster sugar
  • 9 Eggs large
  • 3 tsp Vanilla extract
  • 500 g Self raising flour
  • 75 g Sprinkles

For the buttercream

  • 900 g Icing sugar
  • 450 g Butter or baking spread
  • 2 tsp Vanilla extract

For decoration

  • 25 g Sprinkles

Instructions

  1. Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and grease and line three 8" cake tins

  4. Then add the vanilla extract, and whisk in the self raising flour

  7. Bake the cakes for 35 minutes or until a skewer inserted in the middle comes out clean. Remove from the tins and leave them to fully cool on cooling racks

  8. To make the vanilla buttercream mix the butter and icing sugar together. Once it starts to come together add the vanilla extract and mix until smooth. I use my electric hand whisk to do this but you can also do it by hand with a spoon

  9. If the cakes have domed on top, level them off with a cake leveller or a serrated knife

  1. I'm looking at making a funfetti cake for a friends birthday this week 🙂 Which sprinkles you used as they look like they've kept their colour really well during the bake! A lot of the supermarket ones look really pale and I'm worried they won't survive the heat too well…
