Ocean Waves Ombre Cake – Tutorial

Well, hello!!  I’ve missed you!  It seems I took a bit of an unplanned break – my husband took 10 glorious days off from work and we just played!  He and I even got to sneak away for a couple nights to the coast to celebrate his 40th birthday!  It was bliss, I tell you.  But, we’re back, I’m back, and I have a few fun things planned to share this week!!
First off, I want to get the mermaid party tutorials wrapped up.  I think I’ve covered most everything except for the sweets.  I think the Ocean Waves Ombre Cake made a big impact on the dessert table and it really was pretty simple to frost.  I didn’t take pictures along the way, but I’ll give you the deets and I did a mini-demonstration on a mason jar, so we’ll see how that suffices.

 Supplies:

  • cake, filling, and dowels to support upper tier
  • 2 recipes Swiss Meringue Buttercream (link will take you to my favorite recipe)
  • food coloring (I used AmeriColor in Turquoise and Electric Blue)
  • 16-inch pastry bag, large coupler set
  • Tip #124
  • Turntable for cake decorating

 Specifics:

  • 2 tier cake – 9-inch layers on the bottom and 7-inch layers on the top
  • Rasberry filling (purchased from a cake supply store)
  • One batch of buttercream frosting for crumb coating + base coat

( I tinted the base coat of frosting a light blue, but in retrospect, the base coat did show between some of the ruffles and I wish that I would have tinted the base coat of frosting darker for the bottom tier.)

  • Second batch of buttercream frosting for the “waves” to cover the whole cake
  • To Frost:  Large piping bag, 16 inch, large coupler set, piping tip #124
  • Ombre effect:  After mixing up the buttercream, I added a few drops of color to get a light aqua tint, then scooped one large spatula full into my piping bag.  Then, I mixed in a few more drops of color, another large spatula scoop into the bag, and so on, adding the same approximate number of color drops for each scoop.  If you could see into the piping bag when I started frosting the cake, you would see an ombre color effect with the lightest frosting at the tip and the most saturated color at the top of the bag – make sense? 
  • Now, to pipe:  Hold the bag perpendicular to the side of the cake with the narrow end of tip #124 pointed down and resting on the top edge of the cake.  Steadily squeeze the frosting through the tip while turning your cake (a turntable is pretty much a must for this one!!).  Turn and squeeze until you reach the bottom of the cake and that is it!! 

 Other Tidbits:

  • I typically see this type of ruffle cake done with fondant.  I was too scared to try fondant, plus I wanted the cake to taste good.  The buttercream ruffles are definitely not as “perfect” as I envisioned, but I think the cake as a whole turned out fun and cool!
  • It was warm when I frosted the cake – maybe 80+ degrees in the house – not ideal, so if you can work in cooler temps it will be easier.  However, if it’s warm, don’t hesitate to stop for a bit here and there to pop your piping bag into the fridge and firm up your frosting a little.
  • This buttercream recipe really holds up well in warm weather.  It was around 90 degrees during the outdoor party and the cake held up fine until slicing time.  I refrigerated the cake overnight and up until the party.  (The candy seashells, on the other hand, will definitely melt in the heat/sun.
  • Follow the recipe directions to beat out the air bubbles before piping – you’ll be glad.
  • Anything else?  Questions?  Okay!  Have fun!

    It’s so pretty! I actually love how it’s a little irregular in places, it makes it more ‘ocean-y’ And you make it look so easy! =)

    Hi, just wanted to let you know that I have used a pic of your cake on my blog as inspiration for the mermaid party / cake I just had for my daughter. I have linked back to you, but if that is a prob let me know and I will remove it.

    I tried this cake….. I’ve never even baked a cake from scratch :)
    It’s not nearly as nice as yours but it will do. I have a question about the consistency of the icing. Mine was the same consistency of the soft butter. I missed the let it cool part and started adding butter to the warm egg and sugar mixture. Could this make it less likely to keep its shape? I am going to have order that 124 tip I used a 104 and it wasn’t thin enough to make those pretty ribbons. Any advice welcomed :)
    I’m trying to make this like a sky for my sons 2nd birthday with airplanes as the theme!

    • What a fun idea for an airplane theme!! I would say that two things can make or break this frosting recipe: 1. that the butter is soft enough that you can make an indentation in it if you press gently with your thumb, but not so soft that it totally squishes, and 2. that you let the egg/sugar mixture beat with the whisk attachment until the outside of the mixing bowl is completely cool. After it has cooled and then you whisk in all the butter, switch out the whisk for the beater and beat it until it’s nice and creamy thick. When you’re piping it out from the bag, if it starts to get too runny, stick your bag in the fridge for a few minutes to harden up just a bit (not too long or it will be too hard to pipe out). Good luck! I think it’s super awesome that you gave it a try and you are going to be your own worst critic – your son is going to love that cake no matter what!!

  10. Very sweet little cake. Love your tutorials. Thanks for sharing!
