Gabriel’s favorite thing to eat is sushi, so for his birthday, I decided to make him a sushi birthday cake. A California Roll Sushi Birthday Cake, to be exact.
Since I’m more of a traditionalist and I don’t use fondant very often, I called on my friend Linda who is incredible with fondant. She also just happens to be the Portlandia Pie Lady and makes incredible pies! She’s just all around super talented.
See that detail on the chopsticks? She hand painted them. They are edible too! In fact, everything on this cake is edible, even the wasabi!

I made and frosted the cake at home, and I transported it to Linda’s house to transform it into a giant sushi roll filled with crab, carrots, avocado and rice!

Create Sushi from Regular Birthday Cake
To transform this plain cake into a sushi birthday cake start by cutting out a hole straight through the center of the cake, at least 3” across.
Fondant Coating
Cover the cake in white satin fondant and smooth around the entire exterior and in the middle of the hole you created.
Seaweed
Take a large section of fondant and color it black for the seaweed. Roll it into one long piece, and texture it with a long wooden skewer. Cut a straight edge and line that up with the top of the cake, and then roll it around the sides of the cake and trim the bottom.

Rice
Use the meat grinder attachment on a kitchen aid to create rice! Fill the top of the cake with pieces of the rice fondant until it is full.
Vegetables & Crab
Color sections of fondant to create different shades of green and orange for wasabi, carrots, crab, avocado and chopsticks. Shape into individual ingredients and place inside the whole you created in the center of the cake.
Secret Birthday Plans
Of course this Sushi Birthday Cake was all kept secret from Gabriel and it was well worth it. His reaction was priceless!

That cake is GREAT! Your friend has incredible talent and you’re right – she should totally start her own blog/website/something. Good for you two!
That is fantastic. Happy Birthday Gabe! I need your help Kitty. I am not doing a carnival for Millie’s b-day anymore it was being to stressful for this time in my life so instead, I am giving her a pinkalicious party. Hence where you come in: I need some ideas for pink foods that are 4-7 year old appropriate. I looked up pink foods and all the ideas were like salmon rolls and stuff. Millie loves salmon I don;t think her little friends want thtat at a b-day party however. Do you have any ideas?

What an amazing and clever cake! Love it!
