I have used both oil and butter for the first time and it worked quiet well ..the cake was very moist and soft full of flavors and stayed well for 2 days ...
1 cup flour
3/4 cup sugar - 1 cup powdered sugar (refer notes)
1 cup melted chocolate/chocolate compound
1/4 cup butter
1/4 cup oil
2 ripe bananas
1 tsp baking soda
1 tsp baking powder
1/2 cup cocoa powder.
1 tsp vanilla extract
Grease a 9 inch loaf pan and line it with parchment paper.
Preheat the oven at 180 degree Celsius for 10 mins.
Sift the baking powder ,baking soda ,cocoa and flour together and keep aside.
Melt the chocolate over double boiler.
I just heated the melted chocolate with butter on low flame ,then mixed with a spatula till all mixed.
In a bowl mix together melted chocolate,oil egg and mashed bananas till well combined
Add vanilla extract and mix .
Add sugar and mix well till combined.
Add flour in 2-3 additions and mix well .
Pour in a well greased loaf pan
Bake in a pre heated oven for 35-40 min or till toothpick comes out clean.
If you wish to make this eggless skip eggs and add 1/2 cup buttermilk instead
The cake was very very moist and i actually found it difficult to cut so i would be adding extra 1/4 cup flour next time..
If you are using compound chocolate melt butter along with the chocolate over a double boiler.
The amount of sugar added depends on your taste at first i added only 1/2 cup powdered sugar thinking it would be very sweet but later added extra 2 tbsp powdered sugar.
