How to Make An Octopus Cake  

This octopus cake design would be perfect for all sorts of summertime occasions, including pool parties, luaus, and beach themed gatherings! This would even be an adorable baby shower cake for summertime.

Let's get started!

I've created eight fondant legs (mixed with a bit of tylose powder for faster drying).

You'll want to flatten the end of the leg that will go on top of the tier, so the head can lie flat.  Taper and curl the end of the legs for movement.  Any legs that hang over the edge can be propped up with something until dry--I used a clothespin.

You can make the legs fairly thick but keep in mind that you don't want them to be so heavy that they weigh the cake down.

I also inserted a bubble tea straw into the center of the top tier.  Something has to support this big noggin!...

Creating the Octopus Head

Hello Octopus!  This octopus head  is a Rice Cereal Treat---actually, about 6 of them.  It measures approximately 3 ½" tall.

Press and shape your rice cereal treats into a ball (flattened on the bottom.) Then, rub a light coating of shortening of the cereal treat shape and cover with a layer of green fondant (rolled to about ⅛ inch.) If the head seems a bit too lumpy after covering, you can apply another layer.

Here's the underside...

You can add a little icing to secure the head to the legs.  Isn't he cute?  The little suctions on the legs are piped circles royal icing. (You could also use a crusting buttercream for this.)

Making a Fondant Clam

Now for some cute little details!  I was really excited with how the clam turned out.  First, take some rolled gum paste (or fondant mixed with tylose), shape into an oval, and make lines with a toothpick...

Now, for the big secret! .................

Ice cream scoops make perfect clam shell molds.  Just remember to dust them with corn starch first.

Allow to dry several hours or overnight.  Once dry, it's time  to place onto the cake!  Secure with a little icing....and don't forget a fondant pearl!

Creating the Final Details

I made seaweed, sea plants with various piping tips, including the tip 352 leaf tip and a crescent tip 81.  Also, my trusty round 4 tip for bubbles and misc. plants.  That's the fun thing making sea plants--anything goes!  Reminds me of Dr. Seuss!

Now, time for sand.  Sometimes sand is whatever vanilla cookies are around the house.  Today, I pulverized Cheerios.  To make the sand cooperate, I first spread the board with a little buttercream tinted brown.

  1. Hi! How far in advance did you make the octopus head? I'm wondering how well it will store if I make it a week before...


  2. Hi Stella, You can definitely make the octopus head one or two weeks before the party. Just keep it out of direct sunlight or fluorescent lighting because the colors will fade. Also, do NOT keep it in an airtight box. A bakery box would be fine or any container that can be loosely covered.

  3. Hi amazing cake! I am going to do a version of this for my sons first birthday - how was the hat made and attached to the octopus head?

  4. Hello Rebecca! I'm glad that you are making this! I can't believe that I don't explain the hat...so strange! I made this 6 years ago and so it's been a while...but looking at it I can see that you'll start with a white ball of fondant or gum paste, slightly flatten it into sort of a pumpkin shape. You can add impressions with a toothpick to create the look of seams if you'd like in a x pattern. A put a tiny ball of fondant on top, slightly flattened. Then I took a strip of fondant (which I added ridges to with a toothpick) and wrapped it around the ball to complete the hat. You can use a little water as your glue...or piping gel if you need something stronger. I hope this helps! ;0)

  5. This is such a cute a fabulous Octopus cake!! Thank you for sharing and well done. I'm going to give it a shot for my daughter's 9th birthday next week, eeek! I hope it turns out as nice as yours did.
