Ben 10 Cake (and the PERFECT chocolate ganache buttercream)

It was my brother's birthday last weekend, and to celebrate, we threw him a party at one of those laser-tagging places that is all the rage with hyperactive boys his age. My personal present to him was a Ben 10 birthday cake!

I've never really been interested in cartoon/anime, apart from my obsessive viewing of Sailor Moon, Pokemon and Cardcaptor Sakura on Cheez TV every morning before school back in the 90s. Therefore, I was unsurprised (though slightly put out) when one of the brother's little friends informed me snidely that "Ben 10 [was] for babies!" I was suffering from severe sleep deprivation at the time, due to having gotten up at an obscene hour to put the edible icing transfer and other finish touches on the cake, and it was only out of consideration for my dignity that I didn't snark back. Making little kids cry is uncool, no matter however much they may deserve it xD

This particular cake marked many 'firsts' for me. It was the first time I've put an edible icing image transfer on a cake, and that was a nerve-wracking task in itself. It involved letting the image harden in the freezer, and then taking advantage of the 5 seconds it remained hard when taken out of the freezer to remove the backing sheet, and position it on the cake. I was a bit slow, and as a result some of the image didn't come off the backing sheet, but I managed to cover the boo-boo with the fondant border.

Talking about the fondant...you can see from the close-up above at how shoddy a job I did, but again, this was a first for me! Not only have I never worked with fondant before, but this fondant was one that I'd made myself, using the marshmallow fondant technique. I wouldn't say that it was necessarily cheaper than store-bought fondant when you count the costs of the raw materials and the time and effort that went into making it, but it did turn out to be tastier than the store-bought stuff. There were huge, visible cracks running down two sides of the cake and along the top, and for one heart-stopping moment I thought all was lost when the fondant tore as I pulled it over the cake. Thankfully I was able to rescue the cake, employing the same resourcefulness as I did in those disastrous Design & Technology classes back in high school. 

See, I wasn't exaggerating when I said the cracks were HUGE.

All in all, not the neatest looking cake, but the cake itself (and the filling) was more delicious than any birthday cake we've ordered from professional cake shops. I decided on a no-frills cream cheese pound cake base, filled with chocolate ganache buttercream.

Spreading the buttercream on THICK; I like a 1:1 ratio of cake to filling!

Chocolate ganache buttercream combines the best of two worlds, as its name suggests. There are a few recipes on the internet under the common moniker of "chocolate ganache buttercream", but because I didn't like the sound of any of them, I decided to invent my own. I started by making a chocolate ganache, using the best chocolate I had in the house: 200g of Lindt milk chocolate, 100g of Lindt Excellence 70% dark chocolate, and 100g of Callebaut 70% dark chocolate. I intentionally used double cream which had a high fat content, around 48%. After the chocolate had melted into the 600ml of double cream over low heat, I added in 3 tablespoons of unsalted butter. I poured the whole concoction into an airtight container, put it in the fridge and left it overnight. This is what it looked like when I scooped it out the next morning:

Looks good enough to eat with a spoon, doesn't it? :D My original plan was to use the ganache as is to fill and crumb-coat the cake, but there were issues with quantity (i.e. not having nearly enough ganache to frost three layers) and the fact that the ganache was simply too rich and sweet. The solution: aerate it by whipping it with some butter. The result: a chocolate mousse-like buttercream that was not too sweet, but was unmistakably chocolatey!

I also made some iced cookies using the Easter-themed cookie cutters I recently purchased, but I'll leave the details for another post :)

Here's the recipe for the amazing chocolate ganache buttercream!

Recipe for Lucy's Chocolate Ganache Buttercream

Makes around 3-4 cups of buttercream

Ingredients

200g Lindt Excellence Milk Chocolate

100g Lindt Excellence 70% Cocoa dark chocolate

100g Callebaut 70% bittersweet chocolate

600ml double cream (I used Pura Double Thick Cream, but any cream suitable for cooking should be fine)

375g + 3 tablespoons unsalted butter, at room temperature

Method

1. Put double cream and all 400g of chocolate in a thick-bottomed saucepan, over a gentle heat, until chocolate has melted completely. Keep stirring the mixture and scraping the sides and bottom of the saucepan to stop it from burning.

2. Take the mixture off the heat, and add 3 tablespoons of butter. Stir until butter has completely melted.

3. Transfer the ganache mixture into an air-tight container, and chill in fridge until the ganache has firmed to a spreadable consistency. If ganache is too hard, microwave in 5 second bursts until soft but not liquid.

4. Beat the chilled ganache with a hand beater or stand mixture, until light and fluffy. Add in the 375g of unsalted butter. To help with the butter combining with the ganache, you can chop it into 2cm cubes beforehand.

5. Beat the butter and ganache until it looks like an aerated mousse. Chocolate ganache buttercream, done!

Mango and Cream Swiss Roll

Despite being on summer break from uni at the moment, I don't have nearly as much time to spend on baking and pastry-making as I would like. Yesterday evening provided a rare opportunity for me to carry out two wishes I've had for a while now: 1) try out my flashy new KitchenAid stand mixer and 2) make a Swiss roll.

I've made a Swiss cake roll only one time previously, around a year ago, and the result was not very good. There were visible lumps of flour in the cake part, and the filling made everything soggy. I am pleased to say that this Swiss roll turned out very well. Due to either a superior recipe for the sponge cake, or the use of gelatine-stabilised whipped cream for the filling, or the assistance I received from my KitchenAid, or a combination of the three, this Mango and Cream Swiss Roll had it all in terms of flavour and looks. Okay, almost had it all in terms of looks. But it tasted great, and when baking for friends and family, flavour trumps appearance, yes?

Before I forget - allow me to show off my KitchenAid! Which I've already formed an emotional attachment to xD Whenever I feel depressed about having to go to work, I look to it as a reminder that only some of the good things in life are for free, lol :D

Apart from a minor incident in which I managed to electrocute myself when I touched the mixer bowl because I'd plugged the KitchenAid into an extension cord socket (which wasn't properly grounded), my first baking project involving the mixer went very smoothly. Prior to this, I've always used a hand mixer to make the meringue base for a sponge cake, whip cream for frosting, mix the batter, etc., and I was so surprised at how much effort I was saving myself by using the stand mixer. In fact, I felt kinda guilty and lazy just standing by the sidelines and watching, while my Yellow Pepper-hued beauty did all the work for me. All I had to do was clean the bowl and the whisk intermittently! And assemble the cake roll, of course.

Now, some key pointers when making the sponge cake sheet: 

• Firstly, make sure you have the correct sized pan for the recipe you're using. I've made the mistake of spreading the batter too thinly before, and I ended up with a toffee-coloured sheet which shattered when I tried to manipulate it into some semblance of a roll. I used the sponge cake recipe I found at What's For Dessert Today!, which was perfect for a 9" x 12" (23 x 30cm) pan. 

• Secondly, roll up your cake fresh out of the oven, being careful not to burn your hands. The reason for this is that, if you allow your cake to cool before trying to roll it up, you'll end up with cracks all over. So roll it up while it's still warm. Without the filling, of course. Keep it rolled up while it cools slightly, then unroll, spread out the filling, roll it back up, and put it in the fridge to chill for a few hours.

• Thirdly (and this is a general tip for all sponge cakes), I find that flour lumps are easily avoided by using the "chiffon method" when making the batter. This is where you mix the flour and other dry ingredients with the egg yolks, whip the egg whites and sugar into a meringue separately, then combine the two. This is in contrast to what I did before, which was to sift in the dry ingredients into the wet. 

I mentioned that I used gelatine-stabilised cream for the filling. This is simply a fancy name for cream whipped after gelatine had been added to it. After chilling for a bit in the fridge, it takes on a mousse-like consistency which is perfect for spreading or piping. The gelatine helps it to hold its shape, and stops the moisture from the cream from leeching into the surrounding cake.

Next time, I may puree whatever fruit I choose to use and mix it with the cream to form a pretty, uniformly-coloured filling. I do quite like the distinct chunks of mango in this roll, though :D 

Here's the recipe!

Recipe for Mango and Cream Swiss Roll

Adapted from What's For Dessert Today!

Makes one 23cm long swiss roll

Ingredients

For the sponge cake:

4 large eggs, separated into yolks and whites

70g caster sugar

1/2 teaspoon baking powder

1 teaspoon vanilla extract (I used vanilla bean paste)

10g corn flour (sifted)

70g all-purpose/plain flour

1/4 teaspoon cream of tartar

40ml canola oil

40g milk

For the gelatine-stabilised whipped cream:

1 cup whipping cream

3 tablespoons confectioner's/icing sugar

1 teaspoon vanilla extract (again, I used vanilla bean paste)

1 teaspoon powdered gelatine

1 tablespoon cold water

And, of course...:

Flesh of half a large mango, sliced into 5cm sticks

Method

To make the gelatine-stabilised whipped cream (do this first):

1. Combine the cold water and powdered gelatine, stir together, and set aside until the gelatine has absorbed the water to make a goo. Microwave this goo for 15 seconds or until liquid. Set aside.

2. In a bowl, combine whipping cream, confectioner's/icing sugar, and vanilla extract. Using a stand mixer or hand mixer, start whipping the cream. When soft peaks start to form, add in the liquid gelatine mixture. Continue whipping until stiff peaks form. Do not over-beat or cream will separate and curdle. Transfer into a container, and refrigerate until needed.

To make the sponge cake sheet:

1. Preheat oven at 175 degrees Celsius (350 degrees Fahrenheit). Line a 9" x 12" (23 x 30cm) sheet pan or baking tray with non-stick parchment paper, and place the baking rack towards the middle of the oven, closer to the bottom. 

2. In a bowl, whisk together the egg yolks and 35g of the caster sugar until light and creamy. Sift in the all-purpose/plain flour, corn flour, and baking soda and whisk until smooth and lumps-free. Add in the vanilla extract, and whisk it in well.

3. In a separate bowl (here's where my KitchenAid came to the rescue), add the cream of tartar to the egg whites, and whisk until soft peaks form. Gradually add in the remaining 35g of caster sugar, tablespoon by tablespoon, and beat until stiff peaks form. 

4. Add 1/3 of the beaten egg white mixture from step 3 to the egg yolk mixture from step 2. Stir in with whisk, so that the batter is more liquid. Pour this batter into the remaining egg whites, and fold in gently with a rubber spatula. Be careful as to not deflate the batter.

5. Pour batter into the lined sheet pan and smooth the top with the back of a spoon. Place in oven, and bake for 15-18 minutes, or until the surface is a light, golden brown. 

6. Remove from oven, and straight away, cover the top with a pieces of parchment paper and roll up the cake. Allow to cool slightly, for around 5 minutes, then unroll and fill with the whipped cream and mango. Roll back up, wrap with cling wrap, and put in the fridge to chill for a few hours before slicing and serving.

Happy Birthday, Grandma!

To my dearest Nai Nai,


Simply saying "thank you" for all the love and care you have bestowed on us over the years is insufficient in expressing the gratitude and regard I have for you.

You have taken care of me all my life...even today, as I was putting the finishing touches on the mango cream cake I made for you, you were gathering all the used bowls and utensils and washing them up for me. Despite my insistence that "I'll do it later!" (which I do...sometimes.)

I made this cake for you as an expression of my love. Please accept this humble gift of mine. It is most certainly not picture-perfect, and I could only make use of the materials I had on hand (hence, the somewhat uneven covering of mango), but I know you will only see the good things about this cake and overlook the obvious faults, just like how you always manage to see the good in me. Even when I am behaving atrociously. Even when no one else wants to be around me. Even during those times I don't want to be around myself. Your love for me is unconditional, and I thank you for it.

Happy birthday, Grandma!
