Guest Post: Chocolate and Carrots Shares Rainbows and Sprinkles

Guess what? We got news that the Hubster will be home a whole day earlier than we anticipated!! Woo to the hoo!! I mean……he still won’t be home for almost two months, but still, I’ll take every day I can get. AND. He bought his ticket home! Yay!! Not long now, and this will really be home.

I’d like to take a second and wish my big sister a very super wonderful happiest birthday ever today! I love you, my seestar!

It’s a day of celebration for me all around, so I’m thrilled to introduce you to my beautiful and talented friend Caroline from Chocolate & Carrots. Caroline is one of the nicest, sweetest people I know, and she’s so talented. Not only does she make delicious and gorgeous sweets (usually with a healthy flair), but she also makes some seriously irresistible savories. Today, she made a beautiful, happy cake that is perfect for my celebratory mood!

Go check her out! Meet Leland and drool over her delicious food. 🙂

Thank you, Caroline, for guest posting today! I’m so lucky to have you here!

Hey ya’ll! I’m so excited and honored to be sharing a recipe with Darla’s readers! I’m always ohh-ing and ahh-ing over all of her spectacular treats and now I get to share one with you! Eeee!

Like me, I’m betting that many of you have pinned a rainbow cake….or two, on pinterest. They are fantastically beautiful and so fun to eat!

The only problem with most of the directions, is that you have to have 6 cake pans to make it work! I don’t have that sort of kitchen storage OR oven capacity to handle that many cake layers.

I’m envious of those who do have that space…so jealous! 😀

So, my solution is that you make each colored cake pan batter individually!


It may get old, but you get in a groove of making each layer.

Once one pan goes in the oven, you start combining the ingredients for the next layer. Repeat!

Easy Peasy!

I really wanted to make this tall and beautiful cake, but in turn, it turned out to be a sky scrapper! So, if you don’t want to have to buy extra long cake plates for when you serve your cakes, you will be better off baking these cake layers in a standard 9″ cake pan. I used a 6″, making it ‘mini’…but quite TALL.

It’ll still turn out beautifully…promise! 😀

Either way, this cake is delicious and eye popping!

I hope you enjoy it! Stop by Chocolate & Carrots any time to visit! 😀

P.S. Darla, I am very envious of your new kitchen. Can I come bake with you!?! Can we all?!?

    I bet that was tall. I used 8″ pans and mine was 7.5 inches tall. I did not have a cover tall enough for it. I went to the dollar store and strolled around looking for the correct dimensions. I ended up buying a utility bucket to use as my cake cover.

    I hope you know that every time I view your website, I gain weight! I think I will try the rainbow effect on my neice Zoie’s bday cake this summer. It looks so pretty and yummy. P.s. I am so happy that your hubby is coming home earlier.

    Love it! I made one of these for my son’s first birthday party. We had a crayon theme, so the rainbow colors were perfect. I only had 2 cake pans, so I did two colors at a time. I did 6 layers but instead of making 3x the typical 2-pan recipe I did 2x the regular recipe, so my layers were thinner. It still made a beautifully tall cake, but not too tall. Just have to watch your baking times with thinner cakes.

    I am only 12 years old and I LOVE this cake. Me and my friends are going to get together and make the cake. But how do you make the layers thinner? I would really appreciate an answer!

      You could make the layers thinner by either making less batter (cutting the recipe in half), or by putting less batter int he pan. But if you do this, you have to make sure that you bake the cake for less time or it will burn.
