Serves: 24 slices

Prep Time: 20 mins plus 30 mins for decorating

Cooking Time: 1 hour

What You Need:

  • 2 x bags of Delicious Alchemy Vanilla Sponge mix
  • 2 x 7 inch cake tins
  • 6 large eggs
  • 810g butter (or dairy free alternative)
  • 40ml water
  • 1kg icing sugar
  • 1 tsp vanilla extract
  • ½ tsp Wilton icing colours (we recommend red, pink, golden yellow, leaf green, royal blue & violet).

Gluten Free Rainbow Cake: Birthday Party-How To Make:

Top Tip: For a smaller cake, use half of the ingredients stated above with 6-inch tins instead!

What You Do:

Step 1: Firstly, pre-heat your oven to 180°C (160 °C Fan assisted)/Gas Mark 4. Grease and line the bases of your 7-inch cake tins. Place both cake mixes into a mixing bowl along with 360g of soft butter (or dairy-free alternative), 6 eggs and 40ml of water. Using an electric mixer, mix the ingredients for 15 seconds. Then stop, scrape down the sides of the bowl with a spatula and mix again for another 10 seconds.

Step 2: Divide the mix equally into 6 bowls, adding ½ a teaspoon of Wilton colouring into each bowl – you should have six different coloured bowls altogether.

Step 3: Pour two of the bowls into two of your cake tins, and bake for 18-20 minutes. Before you take the layers out of the oven, check that the cake is golden brown, or insert a skewer into the centre of the cake and check it comes out clean. Once out of the oven, leave the cakes to cool for 5 minutes before you take them out of the tins. Repeat this step with the rest of your bowls until all 6 layers are baked.

Making The Icing:

Step 4: Mix the remaining 450g of butter (or dairy free alternative) with the icing sugar and the vanilla extract in a bowl until thoroughly mixed. Place the violet layer of the cake onto the base of a cake board or large plate, then spread some of the icing over the top with buttercream. Place the blue cake layer on top of this, and repeat the process following the order: violet, blue, green, yellow, pink and red. Or alternatively, you could mix it up! Once all the cakes have been layered with buttercream, cover the rest of your cake with the remaining buttercream.

    I love these rainbow cakes, I've never tried making one though. I'm not sure how to get the bright colour in the cake mix like this. We used to made green cakes for halloween when the kids were small but they were pale (we used to call them mouldy cakes!) I'm wondering if this Wilton colouring is the way to getting the bright colour, or maybe I just never added enough!

    • 19 September 2016 / 15:59

      Thank Julia, I know what you mean, I remember making some Halloween cakes and they turned out pink. I think I did not use enough in mine. This is a guest post and I 've not used the Wilton colouring yet, I will have to look out for them and let you know 🙂
