EAT | Rainbow Cake + 500th BLOG POST!

Hello!!! Today’s post is very special, it’s my 500th post here on AmysBeautyDiary!  Hooray!  I seriously can’t believe I’ve had 500 things to talk about!

Thank you to everyone who reads, it really means a lot to me!  I just love working on new posts and hearing the feedback from you all.

Let’s have some cake to celebrate!  We are making my daughters’ favorite “rainbow cake” today with my special buttercream frosting.  I’m using boxed cake mix to save time, but I will show you how to make the rainbow effect.

What you need:


  • One box white cake mix

Buttercream Icing

  • 2 sticks butter, softened to room temperature
  • 5 cups powdered sugar
  • 3 tbsp milk
  • 1 tsp vanilla

Follow the directions on the cake mix, and then divide the mix evenly into six separate bowls.  

Dye each bowl a color of the rainbow.  Instead of red, we like to do pink.

Starting with pink (or red) pour half of the batter into one cake pan.  Don’t forget to grease your pan!

Just start adding the other colors in rainbow order (ROYGBIV, lol) and don’t stir or touch them, just layer them on top of eachother.

After you’ve done that, you’re going to reverse the order (purple first) and pour the remaining batter into the second cake pan.

Here are both pans finished.

Bake the cakes at 350 degrees for 25-30 min, or until browned.

Let these cool completely.

Now we are going to make our icing.

Put softened butter, vanilla, and milk into a bowl, and beat with mixer.

Add half of the powdered sugar, and beat beat beat.  The longer you beat, the better it comes out, and you want to get all of the yellow color out.

Add the remaining powdered sugar, and continue to beat until you get the desired consistency.  You don’t want it to be runny.

Perfect.  Now you can add your food coloring, or just leave it white.

We did light pink, and decorated it with purple flowers.

I like to refrigerate the cake for awhile, and then serve.  Everyone will be amazed when you cut it open!


Thanks so much for reading!

Here’s to the next 500 🙂
