Pastel rainbow cake in a jar

pastel rainbow cake in a jar

Pastel colours make me happy, eating cake makes me happy. I thought I’d combine these two things together and bake pastel rainbow cakes in a jar.

 I was wary about baking cakes in glass jars, I had visions of the jars exploding, leaving multicoloured cake mix all over the kitchen. However they turned out pretty good, well I think so anyways! Here’s how I made them. I used a boxed cake mix for the first time in a long time, as I read that certain cake mixes can brown easily and the colours can turn muddy. I didn’t want to take the risk. I spent quite a bit of money on the jars and gel food colouring, I wanted them to go right the first time, Luckily they did!

What you will need:
Betty crocker vanilla cake mix
3 kilner half pint jars (Β£2.99 each from hobbycraft)
3 fresh eggs
60ml of vegetable oil
180ml of water
food colouring of your choice (I prefer the gels to liquid)
Preheat the oven to 170 degrees, fan ovens 160. Mix the cake mix, the three eggs, oil and water until it’s blended together. Separate the vanilla cake mix into five separate bowls. Add food colouring of your choice to each bowl. Now comes the messy part. Start scooping cake mix from each bowl and add a few dollops of each colour to the jars. I stacked the colours on top of each other, I didn’t want to mix or blend the cake mix once in the jar, as I didn’t want the colour to merge together and go muddy when baking. 
Fill each jar just about past half way, full of multicoloured cake mix. Before you place the jars in the oven, find a tray and fill it with half an inch of water. This creates a water bath for the jars and the cakes are less likely to brown whilst baking. Pop them in the oven for 30-40 minutes. You should have something like this.. Put a skewer to the bottom of the jar, if it comes out clean, the cakes are done!

Don’t they look pretty? I think the colours look so cool. Leave them to cool for around 20 minutes. Then it’s time to top them with a generous helping of butter cream frosting and sprinkles of your choice.

 I think these cake in a jars would be perfect for birthday’s, special occasions or even as a little treat. If you put the lid back on the jar and place them in the fridge they would keep for around 2 days. The jars are easily washable and if you pop them in the dishwasher they come out like new. What do you think?
