How to Make a Simple Sea Cake

I love decorative cakes, but alas, my imagination exceeds my skill. I wanted to make an incredible cake for my daughter's Under the Sea birthday party, but I needed one that was easy enough for me not to mess up. Too often I find myself the day of an event frantically trying to put together an impossible cake.

This cake was not only simple, but it looked fantastic. It was exactly what I wanted! 

If you want to make a cake like this, all you need is:

  • 2 boxes of white cake mix.*
  • frosting
  • blue food coloring
  • white chocolate
  • small crock pot, a microwave, or a double broiler
  • shells candy mold
  • a spoon
  • vanilla wafers
*I've tried making cake from scratch, and honestly, it doesn't taste all that different from cake in a box. I only use the Pillsbury cake with pudding mixed in; of all the boxed cakes I've tried, that's my favorite.

First, I add blue food coloring to the batter. Don't add the egg yolks to the batter or it will turn green. Cook the batter in four cake pans (or two at a time). Stack three of them on top of one another with frosting in between the layers. Since this was a 1st birthday party, I cut two circles in the fourth to make a smash cake for the baby.

Mix food coloring into the frosting until you get a pretty light blue color and spread it over the top half of the cake. It's easiest to pipe the frosting onto the cake and then spread it with a spatula instead of using only the spatula; you'll pick up less crumbs that way. You'll still pick up crumbs, though, so add a second layer afterwards. 

Mix more blue food coloring into the rest of the frosting to get a darker color and spread on the bottom half of the cake. Using the back of a spoon, make waves in the frosting. When you get to where the different colors of blue meet, blend them in a little bit.

Next, fill a ziplock bag with vanilla wafers and crush them until they're super fine and they look like sand. Line the plate the cake is on with the "sand." You can also pour sand on the top of the cake, if you like.

To make the shells, melt some white chocolate. My preferred method is to put the chocolate in a crock pot on low. That way the chocolate is always at the right temperature and I don't have to worry about it seizing up, and since I had to fill the candy molds three times, I didn't have to reheat it or heat it in shifts.

You can get candy molds in most cake decorating sections of grocery and craft stores, and they're pretty cheap. I found mine in my cupboard the day before the party. I still don't know how they got there.

Once you've poured the melted chocolate into the molds and let them cool in the fridge for ten minutes, arrange them on the cake however you like.

That's it! So easy, right? I had a bunch of extra chocolates so I arranged them on the table, and I added a real shell we found in Tonga to the table because it matched so well.

She loved her sea cake!


  1. What an adorable cake! Looks like the birthday girl enjoyed it :)

  2. Cake and desserts are the best and favorite of our babies; after starting solid foods at the age of 3 to 10 most of the kids love cakes and desserts. Therefore we should prepare it by own in home instead of outside; here also we have found the process of preparing cakes or sea cakes and while following these ingredients I am sure we serve a sea cake for our kids.


I love hearing from my readers!
