Oh this is an amazing cake! You're not going to believe how moist this is. It was very easy to put together, that's a plus in my book. Especially since I had my granddaughters over night and still here for the day, then I had our family dinner to put together. This is very impressive, if you make this for company, they will adore it! This is very light, it doesn't look like it but it is. The banana and chocolate flavors are wonderful in this cake.
I made this in a grease 9 inch spring form pan, I lined the bottom with a piece of parchment paper and greases that as well.. I melted the butter and oil, I used vegetable oil, in a sauce pan and set aside. I combined all the dry ingredients except the salt in one bowl and mixed till combined. I put the melted butter into my KA, ( you can use a saucepan if you have one big enough, I didn't. I slowly added the dry ingredients to the melted butter. Mix well. I then added the mashed bananas and sour cream, mixing only till combined. I whisked together the eggs, vanilla and salt and added it to the mixing bowl, whisking until the batter was smooth. I poured the batter into the pan and baked for about 50 minutes.
The cake had some cracks in the top of it, but the ganache was very forgiving and you couldn't tell after it was frosted. After the cake was completely cooled I started the ganache. I chopped the semi sweet chocolate up, measured out 1/2 cup of heavy cream into a small saucepan and added the corn syrup. The chocolate went in next, I stirred this on low heat very gently until it was melted. I slowly filled the top of the cake with ganache and gently smoothed it working from the center outward to the sides with an off set spatula. It worked beautifully! About 15 minutes before I was ready to serve this I put it into the fridge to harden up the ganache slightly to cut it.
