Rice Krispies Treats

How To Make A SpongeBob SquarePants Cake Topper

SpongeBob SquarePants

We recently created a SpongeBob SquarePants cake with SpongeBob and Patrick sitting at a table in the Krusty Krab and sharing a Krabby Patty. 


How To Make SpongeBob Cake Topper


Here’s how we made SpongeBob with Rice Krispies Treats and fondant.

 Paper Model

 The first step was that we made paper dolls. 

No, we really made paper dolls.  We made simple paper models of SpongeBob, Patrick, the Krabby Patty and the Krusty Krab table to make sure they were all the same scale. 

First Rice Krispie Treat SpongeBob

Here’s SpongeBob’s body made out of Rice Krispies Treats.

Cut Rice Krispie Treat SpongeBob

Once the Rice Krispies Treats had hardened, we used a paring knife to get rid of all of the rounded edges.  

SpongeBob in Carbonite

 It’s SpongeBob in Carbonite! 

SpongeBob’s face isn’t flat, so we used fondant to make the raised portions of his face.  The only reason it’s green is that we had green fondant left over.

 SpongeBob Pinocchio

 Little known trivia, SpongeBob screen tested for Disney’s Pinocchio.

SpongeBob’s nose is long enough that it wouldn’t stand on it own, so we used a wooden dowel to give it added support.

SpongeBob with Fondant Nose

Here’s the nose covered with fondant.



SpongeBob with Egg Eyes

No SpongeBob didn’t meet up with a low flying chicken; Those are two balls of white fondant.

Old Blue Eyed SpongeBob

We added just enough blue to make Sinatra jealous.

SpongeBob with Pupils

It’s amazing how much the pupils add to the face.

SpongeBob with Eye Lashes

 I tawt I taw a puddy tat!

 SpongeBob with red mouth

We filled in SpongeBob’s mouth with red.

SpongeBob gets teeth

All I want for Christmas is my two front teeth…

SpongeBob with Pants

We gave SpongeBob’s pants. 


SpongeBob with Shirt & Tie

SpongeBob looking snazzy with his shirt and tie. 

SpongeBob's Chair

Here’s the barrel SpongeBob’s will be sitting on in the Krusty Krab.

The question is, how do we get SpongeBob to stay in his seat?

The answer…

Wooden Dowel

I think SpongeBob will get the point.

SpongeBob Impailed

Can you say ouch?

SpongBob Seated

Here’s SpongeBob seated.

SpongeBob with arms

Remember how we used wooden dowels to support SpongeBob’s nose?  We did the same thing with his arms.  We inserted two dowels and covered them with yellow fondant.  If you look carefully, you might be able to see that SpongeBob also has legs now.

SpongeBob with shoes

I got shoes, you got shoes…

SpongeBob’s shoes kept falling off, so we used toothpicks to hold them on.

SpongeBob & Patrick

Here’s the final product.

How To Make Patrick Cake Topper

We’re working on a SpongeBob Cake with SpongeBob and Patrick sitting at a table in the Krusty Krab and sharing a Krabby Patty.  Here’s how we made Patrick with Rice Krispies Treats and fondant.

Paper version of Patrick


We needed to make sure that SpongeBob, Patrick, the Krabby Patty and the Krusty Krab table were all the same scale, so we made paper models of each.

Since we’re making a 3-D Patrick, we searched the web for 3-D versions of Patrick and printed them for reference. 



Patrick's Body - Rice Krispies Treats


Here’s Patrick’s body made out of Rice Krispies Treats. I know it doesn’t look anything like Patrick at this point, but it will.  

 Patrick's Body with Arms - Rice Krispies Treats


Here’s Patrick with his arms added.  


Patrick with Big Belly - Rice Krispies Treats 

Patrick has a big belly, so we added more Rice Krispies Treats to his stomach.

You must work with Rice Krispies Treats while they’re hot, so all of this was done in about two minutes. 



Rice Krispies Treat Patrick after cooling



Once our Rice Krispies Treats Patrick had hardened a little, we leveled the bottom of Patrick. 


Patrick covered in fondant



We covered Patrick with pink and green fondant.  I know this looks like the backside of Patrick, but this is actually his front. 



Scary Patrick



We made a small curved indention for Patrick’s mouth and added eyes. 

The whole time we were making Patrick, I kept feeling that he looked like someone else.  When we got to this point, I realized that this version of Patrick looked like Oogie Boogie from A Nightmare Before Christmas.

 Patrick with pupils


We added pupils to Patrick’s eyes and a little red to the inside of his mouth.  It is amazing how much just the pupils add to Patrick.  We could stop here and we’d have a wonderful Patrick.

 Patrick with tongue



We added Patrick’s Tongue. 




We added the blue pattern to Patrick’s shorts. 


Patrick, SpongeBob's Best Friend



And here’s Patrick on the cake.  We added fondant eyebrows and legs.  Patrick is sitting on a barrel at the Krusty Krab.  Patrick’s legs are attached to Patrick and to the barrel.

Rice Krispies Treats Recipe

Rice krispy treats examples

On some of my cakes, I sculpt Rice Krispies Treats.  For example, the pictures above are the Millenium Falcon and an Imperial Shuttle.  Both of these ships are from my LEGO Star Wars Death Star Cake.  


This recipe for Rice Krispies Treats comes directly from the recipe on the Rice Krispies box.  Kellogg’s recipe calls for pouring the hot mixture into a pan.  I pour them onto parchment paper and shape them.
