1I always wonder if I have patience to prepare elegant desserts.In person you will find me most calm who has the solution for everything.  But there are moments where  my anxiety level booms and the all the patience in me goes haywire. And new irritant me emerges.  But I was tiny bit proud of myself when I made this Opera Cake without loosing my patience. And a little bit of basic sugar craft to decorate this dessert also boosted my confidence. Looks pretty na. lol

Today, it was most hot and humid day in Dubai and worse day to photograph this cake. Every few minutes while capturing this slice of deliciousness , I had to freeze for ten minutes and restart again. I had to get this done today itself as tomorrow is Mr.K’s birthday and I wanted to surprise him with this cake. That’s a different thing my surprised didn’t remain a surprise as he smelled the  sweet aroma of coffee around the house and asked why the house is smelling like coffee, did you baked something using coffee.was caught and well the celebration started a day before with a slice of cake of an opera.
The cake is a bit  heavy but  has melt in mouth texture. I luv this kind of desserts. So a moderate slice is just enough to soothe your sweet craving. I prepared this cake for our monthly  challenge of our Baking Partners group run by Swathi of ZestySouthIndianKitchen. This month Savitha of  SavithasKitchen had challenged us to making this french pastry Opera Cake. I have not followed the recipe provided by her as the measurements were too large for two people. 
Mostly adapted this recipe from masterchef australia series specially the base of this dessert ie jaconde.  Chef Gary  has explained opera cake too well. You can search in youtube for the entire recipe. The other parts of recipe ie. coffee buttercream , chocolate ganache are the mixture of few recipes I have googled through out the web. But can assure you the measurements are accurate, as the end result was perfect to the taste. Plus I was able to reduce the wastage. Only 1/2 cup of ganache was extra which I can use later for other icing & stuff. Maybe a  cake pop.
