Shark Birthday Cake and Shark Fin Cup Cakes

Another birthday in our household… my eldest son hit double digits this week! He has a love of sharks and for some strange reason is desperate to do a swim with sharks one day! I thought a shark cake would be very appropriate for him. When I searched for ideas on how to make the cake, there were some amazing creations, but with blood and body parts coming out of the mouth of the shark… not what I had in mind to make for my 10 year old!  This is the first cake I have made where I needed to actually draw a template on paper to the exact size so I had something to copy before I even began.

Domestic Diva: Shark Cake

I have included a photo of the cake before I iced it so you can see how I assembled it. I made a square and small round cake with the mixture and basically cut the cake into lots of pieces to make it fit the template I had drawn up. Then assembled with butter cream icing to hold it all together.

I used the Caramel Mud Cake recipe and Butter Icing. I used natural Hopper blue food colouring with a little bit of carob powder to achieve a grey blue colour. The left over icing I used for the cup cakes. The eyes and teeth are white Marshmallow Fondant Icing and the dark part of the eye is Carob fondant, the same as the fins.

 I also made 30 cup cakes with little shark fins made out of carob Marshmallow Fondant Icing for my son to take to school to share with his class mates.  The cup cakes were made using the too easy choc cake recipe from the Thermomix EDC and I substituted the cocoa powder for brown sugar to make quick and easy caramel cup cakes. I attempted to pipe the icing to make it sort of look like ocean waves.  For the ones with white icing I crushed some blue hooper sprinkles with a mortar and pestle and sprinkled it over the top.

The carob fondant was rolled out and with another template I made from paper I cut out the fin shapes with a knife. I left them to rest for a few hours on a tray to go firm before placing on the cup cakes.

    I love the shark fins! My son is getting married this month and his fiance wants cupcakes like yours for rehearsal dinner. Can you tell me where you got the template to make the fins? Thank you so much.

    • Hi Suzanne, I drew the shape myself on to some baking paper and cut it out to use as the template. I re-used that shape for each fin cutting it out with a knife. All the best for the wedding. 🙂

    Super job! I love this shark… the teeth are just perfect, not to threatening, but not too ‘smiley’ either. You’ve got a real knack for this type of thing, will be watching for what you do next with Thermomix. Thank goodness for birthdays 😉 they really help us stretch our abilities don’t they?

  5. How many cake mixes did this take? What size pans did you use for the head? (square and round)
    Please and thanks!

    Can you please draw a rough template for me? I really want to make this for my son’s birthday party soon.
