Chocolate Ganache and Chocolate Sponge w/Strawberry Cake

My younger sis requested for me to guide her in baking a heart-shaped cake for her hubby's birthday. Kinda worried I can't do a good job as she is comparing with Awfully Chocolate. Oops.. I suggested to put Nutella spread in between the layers, topped with strawberry and then cover with chocolate ganache. At the same time, I also baked 1 more mini cake as I am so infatuated with my new mini tin. Ha~

First, wanna try out the cake as she is bringing home to cut. Secondly, I wanna try to tweak the sponge recipe a little and bake a chocolate sponge out of it. And so, I can have a soft and fluffy chocolate sponge recipe on hand too.. 

The cake is bittersweet from the coco powder even though I didn't reduce any sugar. And it is soft, goes well with the strawberry filling and chocolate ganache. Very light and not too heavy as Awfully Chocolate. Definetely can go for a 2nd serving. I hope my sis will like the cake.. =) And for a 1st timer, someone who doesn't bake, the deco is considered good right.
