Rainbow cupcakes

Updated: May 6

I'm pretty sure you guys must have heard or even tasted a rainbow cupcake, so have I but these cupcakes are so cute and they never get old. These cupcakes are a perfect gift to thank a worker or someone who is helping us during this crisis. You can give these to your parents to thank them for their work or give them to someone in need(if allowed) to brighten up their day.

I love the classic flavour of vanilla with a sweet buttercream frosting with a hint of salt!

I got this cupcake base recipe from https://dinnerthendessert.com and got this amazing buttercream recipe and masterclass from https://cupcakejemma.com/ !

Yup my cupcakes look THAT good!


Cupcake ingredients-

  • 1 cup butter , softened

  • 2 1/3 cups sugar

  • 5 egg whites

  • 1 tablespoon vanilla

  • 3 cups flour

  • 4 teaspoons baking powder

  • 1/2 teaspoon salt

  • 1 1/2 cups milk , warmed for 30 sec in microwave to bring to room temp

  • Rainbow colours of Gel food colouring

  • 1 cup butter (2 sticks), softened

  • 4 cups powdered sugar , sifted

  • 1 tablespoon clear vanilla (if you use normal vanilla it will not be as white, but will be just as delicious)

  • tiny pinch salt

  • 3 tablespoons milk


  1. Preheat the oven to 350 degrees.

  2. In your stand mixer cream the butter and sugar together until much lighter in color, like an easter-y spring yellow (2-3 minutes).

  3. Add in the egg whites and vanilla until totally combined.

  4. Add the salt and baking powder to the flour.

  5. Add in the dry ingredients and the milk alternating 1 cup of flour and 1/2 cup of milk at a time.

  6. Add one cup of the batter to 6 different bowls.

  7. Color each bowl with your gel food coloring in red, orange, yellow, green, blue and purple.

  8. Mix until the colors are fully combined.

  9. Your choice here: Spoon or ziploc bags.

  10. Either add the batter to 6 sandwich size ziploc bags and pipe just enough to make a thin layer of each color (maybe 1/4 inch tall batter layers)

  11. OR

  12. with a small spoon, spoon just under a tablespoon of batter into each cup.

  13. Start with purple, then blue, then green, then yellow, then orange and finally red.

  14. Bake for 18-20 minues

Note- Let your cupcakes cool for at-least 15 minutes before frosting them

Buttercream recipe-

  • 200g very, very soft butter

  • 450g sifted icing sugar

  • 2 tbsp milk

  • 1/2 tsp vanilla extract


1. Add the butter to a mixer and beat for 2-3 minutes on a medium speed.

2. The butter should now look very pale (edging on white) and be fluffy.

3. Add half the icing sugar to the bowl with the butter and start the mixer on a low speed.

4. Once its incorporated turn the mixer up to medium speed and beat for 2-3 minutes.

5. Add the last half of the icing sugar and again start on slow, then once mixed together, increase speed to medium and beat for another 2-3 minutes.

6. Turn down to a low speed and add the milk and vanilla extract.

7. Turn back up to a high speed for 1-2 minutes.

To make the frosting rainbow-

  1. Take food colouring and apply streaks of the colouring in a piping bag fitted with a star nozzle.

  2. Fill your piping bag half way full with frosting

  3. Cut the tip of the piping bag and frost swirls!
