Rainbow bundt cake recipe

Rainbows and cakes, what’s not to like… so why not mix the two together right? I spotted that the food colouring was on offer in my local Aldi, so I grabbed one in each colour. In hindsight, I should have bought two of each as if you want the colours to be darker and brighter, the more food colouring the better. I have baked rainbow cupcakes before, but this time I wanted something bigger and better, I figured it would look pretty cool in a bundt cake version. Continue reading below for the recipe and multiple pretty images of pastel rainbows and sponge cakes mixed into one, d r e a m y.

What you will need:
1 x bundt pan
1 x fry light (plain)
250 grams of plain flour
3 large fresh eggs
1 1/2 tsp of baking powder
230 grams of caster sugar
a pinch of table salt
250 grams of unsalted butter at room temperature

Make sure your bundt pan is washed, clean and dry, I prefer to use a non-stick one as bundt cakes can be tricky to get out at the best of times. The first step is to pre-heat the oven to 160 (fan assisted!) Then get to work on creating the cake mix. In a large mixing bowl, add the softened butter, eggs, and sugar. Use an electric whisk on a high setting, for 2-3 minutes until nicely combined. Now add the baking powder, salt and sift in the flour. Whisk again thoroughly for another 2-3 minutes. Spray a squirt or two or fry light all around the bundt tin, I prefer this to using butter, but it’s up to you all down to preference, really!
Now separate the vanilla coloured cake mix into 5 or 6 different bowls depending on how many colours you want in your rainbow cake! I just cut the ends off of each colour as I knew i’d be using the entire bottle. Mix them carefully using a separate spoon for each bowl, so the colours do not mix together. Whatever colour you want to be the top of the cake, put that in first, mine was red. As I mentioned earlier in hindsight, I should have used more food colouring as it tend to bleach out a little during baking. Carefully add each colour to the bundt tin filling it about 3/4’s of the way, do not mix the colours together, just pour them on top of each other in beautiful rainbow layers you should have something like this. Pop the bundt tin in the oven for around 35-40 minutes, check to see if the cake is done by placing a skewer through, if it comes out clean then the cake is baked, if not leave it in a little bit longer.

Once the cake is done, normally I’d leave it to cool, however with bundt cakes I prefer to get them out of the tin whilst they are still warm, to avoid them breaking or crumbling. Instead of a knife I use a blunt spatula to tease the cake out of the tin, then I turn the bundt tin upside down and tap it onto the plate. After two or three goes it usually comes out perfect (thankfully!) then I leave it to cool before adding icing and a few sprinkles. The whole outside of the cake looks orange / red as the colours bled into each other a little but the real magic, is when you cut the cake open and see inside.

Ta-dah!
No unicorns, glitter or magic went into this cake mix I promise you. Isn’t it pretty? As you can see the blue food colouring didn’t do so well, with lighter colours more is always better. I still think it looks dreamy either way, rainbow cakes are so much fun, perfect for birthday parties or anyone who is just a cake lover in general, cough, cough. What do you guys think?
