DIY: Blindingly Bright Baking

Say that five times fast. ๐Ÿ™‚
In 2010, after obsessing over Kaylah’s mega-bright cupcakes, I tried making some of my own. And since people often wonder how it’s done [i.e. did you swirl the colors together?], I decided to post the very easy steps to brilliantly bright baking. ๐Ÿ™‚
– First off, you want NEON food coloring. The regular kind will look extremely pastel once baked.
– As for the cake/cupcakes…I use box mixes [white or yellow] – and prefer Betty Crocker. Duncan Hines is often too thick to work with.
– Mix all the ingredients like it says on the box, then separate the batter into 2 – 4 different bowls, depending on the amount of colors you want. Dispense mass quantities of food coloring. The more you use, the brighter it will look once baked. I typically use about 1/3 of the food coloring gel tube.
– Layer each batch of batter into the cake pan or cupcake wrappers.
*with cakes you can just pour the mix in straight from the bowl, but with cupcakes it’s easier to spoon in.
Usually I try to cover each previous layer, but sometimes it doesn’t work out. It’s okay! Most people are just amazed that the colors exist within the pastry itself.
The cake’s exterior isn’t too exciting. But once frosted and sliced…
Ta-da! Looks and tastes amazing. ๐Ÿ™‚

My Spanish friend, Aida, grabbing the first slice.
Her comment was, “My teeth hurt afterwards, but it was worth it.” haha!

Do you have any tips or tricks? If so, please share!



  1. I think UK food colouring is different to US stuff because I used normal food colouring and got the most amazing red colour (like red velvet). The green and blue colours were pretty epic too.

    I think I blogged about my rainbow cupcakes as well.

  2. To get the stripey rainbow effect instead of the swirl, I like to tilt my pan and quickly add the colors one at a time. I do this with my Nyan Cat cakes and it comes out perfect everytime ๐Ÿ˜€

  3. Eeep! I remember seeing the finished product picture a little while ago but now the whole process and colors and mini stars, oh my!! ๐Ÿ™‚

  4. Nice! That is so awesome. I made rainbow cupcakes once and they made me so so happy…will have to try out this one too! ๐Ÿ™‚
