You CAN make homemade Rainbow Cupcakes with this easy recipe and tutorial! Delicious vanilla rainbow cupcakes topped with yummy Cream Cheese Frosting.
I know how much you all love my Rainbow Cake – and this Easy Rainbow Cupcakes recipe is an easier, quicker version of that cake! It’s perfect for a celebration, kids birthday party, pride parties, or anyone who loves RAINBOWS (hello!).
When I made my Rainbow Cake for the hundredth time the other week and shared a picture of it on my Instagram (come say hey!), my parents commented to point out that THEY (my own parents!) had never tried my most famous creation!
So I thought, FINE! If they want Rainbow Cake, they’ll get it.
Oddly (realising now I’m probably adopted!) none of my immediate family have much of a sweet tooth AT ALL (and neither does my husband, though he does change his tune when there’s a particular amazing cake around, like my homemade carrot cake!)
So I knew that despite the Instagram teasing, there’s no way they’d eat an entire Rainbow Cake. And I would have to eat the whole thing (challenge accepted)!
SO I made these Rainbow Cupcakes instead! They’re sooo pretty and delicious too – they’re topped with my foolproof cream cheese frosting and adorable bright sprinkles.
Rainbow Cupcakes taste juice the same as normal vanilla cupcakes, and mine are swirled with my delicious cream cheese frosting – my favourite! If you prefer, you could use regular vanilla buttercream, or even a chocolate or strawberry flavoured cream cheese frosting.
What colourings do I need to make Rainbow Cupcakes?
You will need gel food colourings to make these Rainbow Cupcakes – you can get them in Lakeland stores, cake decorating shops, or online! I often buy mine from eBay.
Although they’re about £2 per pot, they keep for years, and you can use them to tint cake batter to make Rainbow Cake, Red Velvet Cupcake, Ombre Cakes… and to colour frostings beautiful colours too.
The colours I used were (click on the link to buy each one):
- Sugarflair Christmas Red
- Sugarflair Melon
- Sugarflair Party Green
- Sugarflair Ice Blue
- Americolor Electric Purple (or you can also use Sugarflair Grape Violet)
Where can I get rainbow sprinkles?
The ones I used here were from Homesense, or you can pick some up in your local supermarket or cake decorating shop. I love really bright sprinkles, and you can find some really great ones at eBay too.
This is the nozzle I used to pipe Cream Cheese Frosting swirls on top of my cupcakes – a 2D tip. It’s really easy and quick to make a pretty swirl using it (see a video showing how here).
Of course, if you prefer just use a spoon to dollop the frosting on and spread it around before topping with sprinkles 🙂
Once you’ve made your cupcakes, keep them in the fridge until about an hour before you’re ready to eat them and they should taste delicious.
- For the cupcakes:
- 200g unsalted butter
- 200g caster sugar
- 4 medium eggs
- 1 tbsp vanilla bean paste or extract
- pinch salt
- 200g self-raising flour
- 1tsp baking powder
- Gel food colouring in: red, yellow, green, blue and purple (click on links to see the ones I used)
- For the cream cheese frosting:
- One batch of my Foolproof Cream Cheese Frosting recipe
- For the Rainbow Cupcakes
- First, preheat your oven to 160C/gas mark 4 and pop some large cupcake cases in a 12 hole muffin/cupcake tin.
- Have your gel food colours to hand, along with four small bowls (cereal sized) before you start.
- In a stand mixer, or by hand, beat together the butter and sugar with the vanilla until it's completely mixed and light and fluffy. Beat in two eggs followed by half of the flour (100g), then the other two eggs and final 100g of flour, plus the salt and baking powder.
- Next, divide your mixture into five bowls (so four additional bowls to the one you're already using), putting roughly the same amount of mixture into each bowl. Start with your purple gel food colouring, using a flat knife to scoop a pea sized amount of colouring into a bowl of batter. Mix the colour in thoroughly, adding more gel if necessary until you have the colour you're happy with. Then, use a tablespoon to divide the mixture into your cupcake cases, one scant tbsp in each.
- Repeat with the blue, green, yellow and red colourings and your remaining batter, and then bake your cupcakes for 15-20 minutes in the middle of your oven. We don't want to bake them on the top shelf as they will brown and you'll lose some of the effect of the rainbow!
- Make up the cream cheese frosting according to the recipe (when the cupcakes are baking is a good time) and use it to frost your cupcakes before topping with sprinkles.
