Celebrate a special birthday with a Rainbow Tie-Dye Surprise Cake
Cut into the brightly colored cake to reveal the surprise.

After the first slice 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

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 1/2 tablespoons of lemon juice and 2 cups powdered sugar then pour it over top.

This cake make 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 when this cake was slices was the ultimate reward.

This reaction you’ll get when cutting into this cake will change your life.

Can you image the reaction you’ll get when this “Marry Me?” Reveal Cake  is sliced?

I know the reaction you’re hoping for and I wish you all the best if you make this cake for your sweetheart.

    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. :)

      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.

    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!

    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!!

      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.

    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! =)

      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.

    Hi Beth! This cake is amazing! I wanted to let you know that we will definitely be featuring it at Fun Family Crafts, but I had to change the address to direct our readers to where the tutorial actually is at Tablespoon.com. Looking forward to seeing your next creation!

    Hey, how did I miss this last week? So awesome! I really love your matching tie-dye fondant and number inside. Great idea. (Thanks for the baker's love too. You're sweet to link to my Peace Cake, Beth.)

    • says

      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!

    Can you make this with a basic homemade batter? I have two children with dairy and egg allergies so I have my own recipes. I would love to do this for my oldest son's birthday in September.

      If you hover over any image on my page you'll see big "P" pin button. Just click on that and you can add the pin. You can also scroll to the end of the post and use the P button in the row of social media share buttons. It's in between the G+ and the Facebook button. Thanks!

      I have not, but I'm sure it would work just as well. I used the Betty Crocker Pound Cake because I made the cake for the General Mills website, and they require that I use their products. It's a nice pound cake with good flavor and texture and it's very similar to homemade, so I can't imagine why the homemade would not work the same.

    Why wouldn’t you just cut the first cake into the shape you want, instead of a bunch of cut outs and then bake it in the second cake?

    • says

      If you have the skill to sculpt a number out of the very long cake, then you can certainly do it that way. I wish I had that ability, but I don’t. I found it much easier to use the cookie cutter.
