Welcome to the She Who Bakes tutorial on how to make these fabulous little rainbow cupcakes!


Preheat your oven to 140° and then cream butter and sugar until is it light and fluffy.


Then add the eggs one by one, combining as you go.


Sift in the flour, bicarbonate of soda and cream of tartar.


Finally, add in the milk, one third at a time and the vanilla extract and mix on a high speed for approximately 6-8 minutes.


Then you want to line up six bowls and six colours to represent your rainbow. Divide your cake mixture into your six bowls. (I’ve used the sugarflair colours poppy red, melon, tangerine, party green, ice blue and grape violet.)


Then comes the fun bit, start colouring your mix accordingly.


Start to fill your cupcake cases by using one teaspoon of your purple cake mixture…


Then continue to fill using a teaspoon of different colours going blue, green, yellow, orange and finally red to get your rainbow look. Once you have completely filled your cupcake cases 3/4 full, bang the tin quite hard on the surface a few times to get any air bubbles out and to even out the colour in the cases.


Bake for 20-24 minutes. Keep an eye on the cupcakes to make sure they don’t start to rise too much. Once your cupcakes are baked, take them out of the oven and let them cool in the tin for 5 minutes before taking them out.


You should now sit back and feel very proud of yourselves. You can either leave them like this in their simple majesty or decorate them as you wish.

Give them a go and let me know how you get on, either on Facebook or Twitter.

Happy baking!
