Water (as stated on cake mix)
Oil (as stated on cake mix)

Buttercream frosting (optional)
- Preheat you oven to 350 degrees F (175 degrees C). Grease and flour two 8-inch round cake pans.
- Prepare your cake batter as instructed on the box.
- Divide the cake batter into six separate bowls. Use a toothpick or teaspoon to scoop a dab of food colouring into one bowl of batter and stir; add more food colouring, if necessary, to reach the desired shade.
- Repeat with the remaining colours and bowls of batter.
- Pour your coloured batter into each of the prepared pans, alternating the colours. The rainbow colour pattern is firstly red then orange, yellow, green, blue and finally purple.
- Bake in the preheated oven until a toothpick inserted into the cake comes clean, about 30-35 minutes.
- Cool in the pans for 10 minutes before removing to cool completely on a wire rack.
- Once completely cool, slightly trim off the top of one of the cakes to make a flat surface. Doing this will allow you to stack the other cake and prevent it from tipping off.
- You can leave the assembled cake without filling or put some filling of your choice in between the layers if you wish. Afterwards you can then frost your rainbow cake and add some sprinkles. Enjoy.
*Important Baking Tip:
If you really want to make a superb rainbow cake, with bright vivid colours you should use gel or paste food colours. Do not try using liquid food colouring as your rainbow cake is less likely to come out really well. However, if you are keen to experiment, you can go on and use liquid food colouring. You will have to use a bit more than you would with gel/paste colouring in order to get the vivid colours.
To make orange food colouring, mix 1 drop of red food colouring with 2 drops of yellow food colouring into a bowl. Then stir with a toothpick to mix. If its too light (and you want darker orange) add more red and if it’s too dark (and you want a lighter orange) add more yellow.
