- 180 °C, line a 18x10cm round baking tins.
- Chop the chocolate blocks, put it on a microwave safe bowl, set for 1 mins 30secs, paused every 30secs to avoid burning the chocolate.
- Put the muscovado sugar into a bowl and add the boiling water until dissolve, set aside.
- Put the flour, baking powder and bicarb in another bowl, set aside.
- Beat the butter and caster sugar until pale and fluffy. Add vanilla extract to the butter mixture, still mixing, then add the eggs one at a time, then add the flour mixture.
- And the last, fold in the melted dark chocolate and muscovado sugar mixture.
- Pour into the baking tin, bake for about 30 minutes or until a skewer comes out clean. Let cool.
For the decor, I want to try making the shaved chocolate or chocolate curl, but I don't have those proper tools (flat metal spatula and metal scraper), so I just use my knife and a ruler (!). Please look for tutorial on the web for more precise and professional steps.
I just melt the rest of the chocolate block with 70ml vegetable oil (as substitute of 1 tbsp of Crisco shortening) in a microwave. Mixed until even, then pour into a clean and dry and flat surface, spread it as thin as you can. Then leave it until firm and set, after that you scrape it to one small section at a time to make a curl. Since I don't have those nifty tools, I ended up with rather thick layer of chocolate mixture (you can see it in the pic), and it's a bit hard to scrape. As the result, instead of chocolate curls, I got chocolate barks because they resembles tree bark :) Looks awful but taste good tho..
Then, I made a frosting, not from heavy cream or butter or other type of usual suspects of frosting. My frosting is mascarpone cheese and icing sugar, sounds weird, isn't it?
For my frosting :
3 tubs of mascarpone cheese, softened in room temperature.
75gr-100gr pure icing sugar ( you can use more or less to suit your liking)
Beat them together until even.
To assembly :
- Slice the cake horizontaly with serated knife. I got 3 even layers and 1 super thin top crust, I only use 3 layers because the frosting is for 3 tiered cake.
- Place one cake layer on a plating dish/base, spread with 1/3 of the frosting. Repeat with the other 2 layers. Decorate as you desired, but in my case, I cover it with chocolate barks.
