sponge bob cake video tutorial howtocookthat

Who lives in a pineapple under the sea? Spongebob Squarepants! This weeks video tutorial shows you how to make a 3D spongebob cake in the style of the ‘spongebob out of water’ movie.

How To Cook That recently won a Taste Award for Best Food Program as well as Australia’s best cooking blog. Thanks everyone who nominated me 😀

To make the spongebob cake you will need

2 quantities of the red velvet cake baked in two trays 1.5cm (0.59 inches) deep x 38cm (14.96 inches) long and 25cm (9.84 inches) wide
A piece of paper 17.7cm (6.97 inches) x 7.8cm (3.07 inches) to use as a template for cutting your cake.

1 quantity of cream cheese frosting
2 quantities of buttercream frosting
yellow 1kg (2.2 pounds). I had approximately 300g (10.58 ounces) left over but you’ll need the extra to roll and drape over the cake
50g (1.76 ounces) black
brown 150g (5.29 ounces)
white 300g (10.58 ounces)
red 50g (1.76 ounces)
blue 50g (1.76 ounces)
Tylose power (used to make the fondant details dry out faster, but if you are making the details ahead of time, you do not need this)
optional: cream filled shortbread biscuits to make the ‘sand’ to cover the board

    Hi Anne!

    Thank you for being one of my inspiration. I was able to make this cake after watching your tutorial. Although I did not use a template to make this one, I was happy that it was successful.
    I became one of the suppliers of wedding cakes here in the city. A lot of people thought I went to school for baking and cake decorating. It’s an overwhelming compliment. ?

    I used a mud cake recipe for this cake and covered it with a dark chocolate ganache.

    Great tutorial! I have had a real win with this! I have used a vegan cake and buttercream (dairy and egg allergy) and it’s worked beautifully! Thanks so much!!

    • Awesome to hear Amanda ?

    I make stand up sponsbob so i confused how make the body and the arm have spatula and craby patty?

    • Hi Nathalia, the arms are very skinny so getting them to support the weight of a spatula will not be possible unless you use wire or smoother support inside the arm fondant.

  5. Hi can I just say, I love love LOVE your sponge bob cake from 2014, I watch it every year and I finally attempted to make it, it worked out perfectly, thank you so much, you’re amazing!

    • that’s awesome Yumma
