A rainbow cake in a jar is perfect to give as a gift and so much easier than cooking all of the layers separately

Ingredients

  • 100 g unsalted butter, at room temperature
  • 100 g caster sugar
  • 2 medium eggs
  • 100 g self-raising flour
  • 6 gel food colouring, in a variety of colours

For the buttercream:

  • 100 g unsalted butter, at room temperature
  • 200 g icing sugar
  • bright coloured sprinkles, to decorate

How does this work?

It's simple.

With just one click, all these ingredients will be put into a basket on mySupermarket.co.uk.

You can select the products you need, compare prices and choose the retailer you wish to buy them from. Or you can leave them in your basket and come back later to buy items from other recipes.

One thing is for sure though, you are guaranteed to find the best value.

Method

1. For the cake: Preheat oven to 180C/160C fan/gas 4. Cream the butter and caster sugar together until light and fluffy. Add the eggs to the mix a little at a time, alternating with a spoon of the flour to prevent the mix from curdling. Add the remaining flour and mix thoroughly. Divide the mixture into 6 and put into individual bowls.

2. Colour the batter in each bowl with the colouring. Go slowly, adding a little colour at a time until you reach your desired colour. Don’t be tempted to make the colour too dark as they will darken further as they bake.

3. Once you have your 6 colours mixed, you can begin to assemble the rainbow. Carefully spoon your first colour into the middle of the jar, being very careful not to touch the sides. Using a teaspoon, carefully work the batter around the bottom of the jar until you have an even distribution throughout. Proceed in a similar fashion working your way through the whole spectrum of colours.

4. Fill a tin with approximately 3cm of water and place your jar in the tin, leaving the top of the jar open. This water will create steam inside the oven that will help to keep the cake moist during the baking process.

5. Put the tin in the centre of the oven and bake for 40-50 minutes, or until a skewer comes out clean when inserted. Remove from the tray once baked and place on a cooling rack.

6. For the buttercream: Cream the butter and icing sugar together until light and fluffy. Once the cake has cooled completely add the butter icing and sprinkles.

Any recommendations for types of jar to use?

Hi Claire,

It's best to remove the rubber band when you bake and replace it afterwards, but the cooking time will be the same no matter how many jars you make.

Let us know how you get on!

Hi Anna!
I was wondering if you need to alter the time and heat if you do more than one at once? And also do you remove the rubber ring or anything before putting in the oven?
Thanks Smile

Hi Hannah, thanks for comment - this cake is just like any other so I would treat it the same way, you can store it in its airtight container for a few days but it has to be eaten within that time. I would make the cake on Christmas Eve ideally, but you could make it the day before, then give it as a gift on Christmas Day.

Enjoy!

Hello, how long does the cake keep for in the jar? If I gave it as a xmas present what would be the recommended time to make it and eat it by. Thank you

Hi Liz and Jenny, thanks for your comments - this recipe is a bit of a novelty, which makes an unusual gift. It makes 1 cake in a 1/2 litre jar, so I will update the recipe to avoid any more confusion. I have received cakes in jars before; you close the lid before you give it as a gift and then you eat it with a spoon.

Me too -- what size jar -- and are you supposed to close the top before giving it as a gift. Looks rather complicated to me. How are people supposed to eat it? Spoon it out. Bit gimmicky I think.
