Creating a boy’s 5th birthday cake Part 2

Posted By on Sep 26, 2010 | 6 comments

Finally I have the time to post my son's 5th Birthday cake!  Even though it was two weeks ago, things just crop up - as they do!  My son helped design the cake, and I love encouraging my kids in the creation process of their cake.  These are the steps I use when we design a cake together:

1) What theme would you like? (Sometimes he asks for what he had the year before, but I want a challenge too, so it has to be something new). If the kids can't think of a theme, we check out the Wilton website for ideas and work from there.  He wanted a frog theme for his 5th birthday cake with a frog on top, but not part of the icing like the pirate cake I'd done previously.

2) What flavour cake?  He wanted chocolate and strawberry.  So I decided to make a chocolate and strawberry flavoured marble bundt.  Originally I thought of filling it with strawberry mousse, but I wasn't sure of the weather for an outside party, so I ditched the filling.  He also wanted strawberry filled freddo frogs around the outside of the cake, but because of unknown weather conditions, I thought it best not to so that I didn't have melted chocolate everywhere- see I learned my lesson!

3) What flavour frosting or icing?  He wanted chocolate, so I've used my favourite best chocolate with sour cream frosting recipe by Nigella Lawson- so silky smooth and really tasty, holds up well in slightly warm temperatures.

So, here is the final cake (recipe included!)

The frog was hand molded with store bought sugar paste. I prefer using Wilton's gel colours- the colours are strong and pure. I molded the lily pads as well, mixing a bit of green and yellow colouring gel to give a softer colour. The flowers were store bought as I didn't have the time to pipe my own.The most disappointing part of the cake was the use of Wilton's decorating gel in a tube. I wanted to write my son's name on the cake (you can see there's a dip in the frosting next to the blue flower) and it bled everywhere. So I scooped it out and just embellished the frog's feet- a waste of $6+, that's what I get for being too lazy to make my own royal icing for the cake!

 Mmmm another cake lesson?!

My son also asked for sprinkles around the outside, so I used a dinosaur sprinkle mix- the colours worked well.

Recipe for the chocolate strawberry marbled bundt cake:

250g unsalted butter
1 ¾ cups sugar
¾ cup sour cream
5 eggs
1 ½ teaspoons vanilla
½ tsp salt
3 cups self raising flour
100g custard powder
2/3 cup milk (plus 3-4 tablespoons extra)
2 tablespoons dutch cocoa
2 tablespoons golden syrup
¾ teaspoon pink food colouring gel
2 tablespoons strawberry flavouring

Preheat oven to 180C.  Grease and line a 22cm thick (not thin like for sponge cake) spring form tin.  Cream butter until soft and fluffy, add sugar a 1/3 at a time until all incorporated and fluffy.  Beat in sour cream and vanilla.  Lightly whisk eggs and add to mixture a third at a time while still beating.  Sift in flour, custard powder and salt.  Beat until combined, adding milk a third at a time while the beater is still running until all the mixture is well mixed.  Beat mixture on high for 1 minute, it should become lighter in colour.

Add 1/3 of the batter into another bowl, this is for the chocolate filling.  Sift in dutch cocoa, and mix together with golden syrup.  You may need to add a few tablespoons of milk extra to this if it is too dry. 

In the remaining 2/3 add food colouring and strawberry flavouring, and mix well so that the strawberry colour is even.  Spoon half of this strawberry batter into the pan, then add all the chocolate on top, making sure you don't smooth it out to the sides.  Add remaining strawberry batter on top.  Using a fork swirl the mixture from top to bottom in a loose circular fashion, moving around the tin, maybe 5-6 swirls to roughly marble the colours.  Put pan into preheated oven on the middle tray, and bake for 60 minutes.  Test cake with a skewer to check if ready.  Remove from oven and leave the cake in the tin for 10 minutes.  Release cake from tin and allow to cool for 20 minutes.
Chocolate Frosting (adapted from Nigella Lawson Old Fashioned Chocolate cake recipe)
200g quality dark cooking chocolate
80g butter
1 large tablespoon golden syrup
125g sour cream
1 tablespoon dutch cocoa
300g sifted icing sugar
Melt butter and chocolate in the microwave on medium heat, stir to mix together.  Add golden syrup and icing sugar, and beat well with a whisk.  The mixture should have cooled enough to add the cocoa and sour cream.  Keep beating until thickish in texture.  Smooth over outside of cake, and fill a piping bag with the remainder, and pipe decorative edges.  This frosting is great as a cake filling also.
I really love baking with my kids for their birthday, my daughter's 2nd birthday is coming up in a few months, at the moment we're tossing up between Dorothy the Dinosaur as a theme or princess, we'll see what creative insipration happens!

  1. Looks great. Looks like the frog prince on the cake.
    Was it yummy?

    • Thanks- the frog prince didn’t taste too bad either, my son ate one of its legs and said it was delicious! This frosting is one of our family favourites for cakes and cupcakes. The strawberry part tasted an smelled like strawberry, and the chocolate tasted like chocolate- I get disappointed when you get a marbled cake and both colours taste the same.

      And for the ultimate taste review- try the recipe for yourself- let me know how you go!

  2. This bought back memories from when my children were younger, and we would spend hours pouring over recipe books for “just the right one”. They ranged from Humpty Dumpty to Minnie Mouse to Giraffe cakes.

    Congratulations on your amazing effort. Mine usually were a simple sponge cake, but the children loved it. I am impressed how good yours looks.

    • Ta Brenda, it’s really exciting experience that shares with your children the passion and joy of researching to create something in a collaborative way. They love the whole process- especially the end, I think we had one frog leg left by the end!

  1. It’s chocolate time - [...] the cupcake was filled with chocolate custard, made on melted dark chocolate, and topped with my chocolate sour cream frosting,…
