A rainbow drip cake can be a fun cake to have. You can make it a simple rainbow cake loaded with colorful candy. This is a step by step tutorial on how I made this lollipop rainbow drip cake. It also includes the rainbow cake recipe, as well as everything you need to know about making the perfect drip, including the type of chocolate, colors or candy.

How happy does this cake look? Colorful cakes make me happy, very happy.
I made this for my Aadi's 11th birthday this year. Its been two months and I have still not shared this cake with you. Well, I did make a video for the recipe and tutorial on how I decorated this cake. But, by the time I got my act together with editing the images and the video, I realized two months had gone by. The inside of this cake is my rainbow cake. It has been a popular recipe on this blog but the images on that post were old, from before I had this awesome camera. So, I thought it was time to give that post a facelift. As a result, my popular rainbow cake recipe now has the inside of this beautiful cake. See how pretty? Colorful on the inside and out. Just like my boy.

My Aadi's birthday cake
This was one of the three birthday cakes my Aadi had this year. He wanted a colorful drip cake for his birthday, so he asked me to make a rainbow cake. As planned, he was supposed to share this cake with some of his friends at the bowling alley but unfortunately, he fell sick the day before his birthday. Of course, we did not want him to celebrate his birthday while sick (and of course infect others with his virus), so we had to cancel the birthday celebration.
Of course, according to the plan I had already made or was in the midst of making him his birthday cake. So, we had a beautiful lollipop rainbow drip cake for his birthday which we celebrated just with the family.
The bowling alley party was postponed by a week and I had to make another cake. But this time, instead of making the same cake again, I made the standing emoji cake. And I shared a tutorial on how to make an emoji cake with you last week. I mean how to make a standing emoji cake, yeah I made a gravity-defying cake. My kids...!!

Cake
As I said above, the cake is my rainbow cake recipe. It's a very versatile recipe and you can either make a tall cake with seven layers of the rainbow, as I have done here, or you can divide the batter into six colors. You don't have to make it tall. If you choose to use a 7-inch cake pan instead of 6-inch, as I have, you will have a shorter cake. As I said, it's very versatile. If you read the post I have explained it in detail. And of course, feel free to ask any questions in the comments section below. I am always happy to answer.
Frosting
I have used my favorite Swiss meringue buttercream for this but you can also use my velvet American buttercream or Italian meringue buttercream recipe. A word of advice - If you want to make tall-layers without any internal support, the secret is good butter-based buttercream. Yes, the buttercream, when chilled in the fridge, helps support the layers, aka the tall cake.
Candy
It's all about the candy on drip cakes. You can use any candy you want. I have used inexpensive lollipops here only because my son wanted a colorful cake. When I went to buy lollipops, the ones with the brightest colors were these. So I picked them up.
Wafers
Honestly, you don't really need wafers, but I liked the effect you get when you add these wafers. However, these break easily and they soak up any moisture. So, be aware of what is on that cake. If you use any sauce, you will end up with soaked up wafers.

Chocolate or candy melts
Candy melts work best for drip cakes. Yes, unlike coverture chocolate, which I love very much, candy melts work best if you plan to make a drip cake. Once you have melted the chocolate, add just a little cooking oil or coconut oil to the melted chocolate. This will give you a pouring consistency as I have shown in the video.
My son did not want too much chocolate on this cake, so I used only as little as I needed for the drip. You could use more but make sure you control the drip. If you add too much melted-chocolate on top of the cake, it will continue to drip, which may be more than you need.
Tip: I find the best way to control the drip is to pour over the edges first. Then, let the edges set a tad before pouring the rest of the melted chocolate on top. The set edges will prevent any more drips. Makes sense?
Drip effect without chocolate or candy melts
Need to make a drip effect without using candy melts or melted chocolate? Yes, you certainly can - with royal icing. Just make a pouring consistency of royal icing in the colors you need and then do the same as I have with the candy melts. Also, use the same drying technique to control the drip.

Edible colors / Candy Colors
Ideally, it's best to buy candy melts in different colors. If you don't work with chocolate much, this would be the most inexpensive method. If you choose to color your own chocolate or candy melts, please remember that not all edible food colors are suitable for chocolate or candy melts. You need an oil-based color for chocolate/candy melts. So, not all edible color gels that you use for fondant will work with candy melts. Which is why I highly recommend using different colored candy melts (or make a royal icing drip cake).
Last but not least - doweling the cake
I have not used any dowels in this cake. We wanted tall cake slices with all 7 colors for each slice.
I know we've all been told that we must dowel our cakes. And generally, that is true. Once your cake has reached a height of 4 inches or maximum 6-inches tall it's time to think about doweling. Why? Because the weight of the top layers will usually be too much for the bottom layers
Sometimes, you can get away without doweling if:
- You have a single-tier cake, which means there is no weight from the top tiers nor is it balancing on any bottom tier.
- Or, you are using a good buttercream recipe, and by that, I mean
all butter buttercream. In this case, the Swiss meringue buttercream between layers and around the cake gets stiff so the layers stay in place.

Thank you for this cake recipe and tutorial. I made this for my daughter. Her birthday was around Christmas. She loves the rainbow effect. Mine was not as pretty as yours but it was so tasty. And I used lots of Christmas candy on the top.

Thank you for this cake recipe. I made only the cake not the drip. Used it for our Christmas pudding. I frosted with your 5-minute vanilla buttercream frosting. Everybody loved it.
