Celebrate a special birthday with a Rainbow Tie-Dye Surprise Cake! This cake is full of surprises and will be sure to wow your friends and family when you cut into this brightly colored dessert!
After the first slice of this Rainbow Tie-Dye Surprise Cake is cut, you reveal the #5 hiding inside to all the party guests.
You'll hear oohs and aahs and the obvious question, "how did you do that?"
Will you reveal the secret? That's up to you!
Can you guess how that number got inside that cake? Would you believe me if I told you it was magic?
After spending all day creating this dessert, I can assure you it was not magic. Twitching my nose or waving a wand would have been a great way to create this, but alas, I am a mere mortal and had to do it the hard way.
If you are curious as to how it was created, you can see the step-by-step tutorial to
make my Rainbow Tie-Dye Surprise Cake over at Tablespoon.com.
But, before you go, check out these other cake ideas.
For those of you who don't want to spend an entire day making a cake, but still want the cool tie-dye rainbow effect inside a cake, you can try this idea.
Doctor up a Betty Crocker Pound Cake Mix by adding a tablespoon of lemon zest and 2 tablespoons of lemon juice. Make the rainbow pound cake using the simple technique shown on the Rainbow Tie-Dye Cake tutorial and stop there. Just serve the cake as is or to make it extra lemony mix together 3 ½ tablespoons of lemon juice and 2 cups powdered sugar then pour it over top.
This cake may look pretty plain Jane on the outside, but one slice will reveal a burst of color within.
If you aren't a fan of rainbow or want a cake for a different holiday, it's easy to change it up.
This Red, White, and Blue Tie-Dye cake was created using the same tie-dye technique but has a different color palate which completely changes the look of the cake. It's perfect for the 4th of July, Memorial Day, Flag Day, or Labor Day.
The recipe used for this cake is one of the best I've ever made. I know you'll agree if you are a fan of coconut. The delicate cake has the most lovely coconut flavor but the real show stopper is the coconut buttercream frosting topped with white chocolate ganache. It's heavenly.

If you are willing to put in the effort but want to celebrate something other than a birthday, it's easy to make a few tweaks to create a fabulous cake for any occasion.
Check out my recipe and tutorial for this Raspberry Lemon "I ❤ You" Valentine's Day Reveal Cake. The dessert was a true labor of love. I'm not going to tell you it was easy to make, but the reaction I got I cut the first slice was the ultimate reward.
This reaction you'll get when cutting into this cake will change your life.
Can you image being served this "Marry Me?" Reveal Cake?
These surprise inside cakes can be created for just about any occasion.
I created this cake for my nephew's eagle scout ceremony. Everyone in the room gasped as he cut the cake. It was the largest crowd to view one of these cakes being cut and I loved seeing their enthusiastic reaction.
The crowd was even bigger when I served this wedding cake a few months later.
The bride and groom tied the knot at our annual Halloween party, thus the design of the cake.
As they cut into the cake to reveal the surprise hiding inside, my heart was beating so hard. I was nervous that I placed one of the cakes backwards. I can't tell you how thrilled I was that I was wrong. The cake looked perfect.
I've created quite a few surprise inside cakes, as well as, semifreddos on this site. These projects do require quite a bit of effort, but I've done my best to give you great instructions to follow so that you can make them yourself.
If you have any questions while you are working, don't hesitate to ask.

WOW ... sooo cool! Love how the tie-dyed number and fondant coordinate! You made tie dye cool again ... just like the 70's!

Having grown up in the 70's, I was all about tie-dye. We made new shirts every summer.

Your peace cake was one of my favorite surprise inside cakes and it was the perfect inspiration for my cake. You are really the most brilliant food designer I know!

Lindsay Ann says
This is the coolest most creative "surprise inside" cake I have ever seen, love it Beth!!
beth says
Thanks, Lindsay Ann:)
Anilu F says
Loved it!!!
I'm intrigued by the texture of the 'twice-baked' cake... is it too different from the white pound cake?
Regards from Perú! =)
beth says
Anilu, it is the strangest thing, but even though the 5's are already baked when they go into the pan with the raw cake batter, they don't taste any different than the rest of the cake once it's all baked. I really can't explain the science behind it. I'm just happy it works:)

It is because the cake mixes you are using are full of chemicals and have an indefinite shelf life.
All those food dyes are SO harmful for human consumption.

wow, beth. I checked out the post on tablespoon.com. you continue to amaze... this is SO COOL! (I've always been a fan of your surprise cupcakes, but the possibilities for this are endless...) the tie-dye cake alone rocks! so excited. I'm hopeful to hear about the new wilton fondant though - I think fondant is so yuck! I much prefer using your candy clay.... :0) thanks again!!
jodi from atlanta
beth says
Thanks Jodi. I love how this cake turned out. I too prefer modeling chocolate (candy clay) over fondant, but covering a large cake with modeling chocolate can be challenging. This new fondant is so good that I now am happy to cover a cake in fondant. I'll still use modeling chocolate for lots of projects, but am happy to finally have a fondant I like using.
The Partiologist says
Lemon pound cake sounds delicious and to serve a tie dye version would be a surprise to all! I think the 5 year surprise inside cake is one of my favorites of all time!
beth says
I ate way too much of the lemon pound cake. It was such a nice change from cookies and yellow cakes.
Lisa@hooplapalooza says
HOLY COW!!!!!! you are just WAAAAAY too cool for school! :>D
beth says
LOL! I was a total dork in school, so it's nice to know that at my age I'm now cool:)
June says
What a beautiful cake! I'll have to try that tie-dye pound cake, that is probably the coolest loaf cake I've ever seen. 🙂
beth says
Thanks, June. I thought the colors in the pound cake were so pretty and everyone who got a slice was intrigued by the method I used to create the colorful effect.
