Preheat the oven for 10 minutes at 180 degrees.
Line a cake tin with grease proof paper.
Peel and mash the banana in a large mixing bowl.
Crack the two eggs in a small bowl, then add it to the banana.
Add in the sugar, oil, chocolate powder and instant coffee powder and whisk till frothy.
Into the same bowl add whole wheat powder, muesli, baking powder and baking soda.
Gently fold the dry ingredients into the wet ingredients.
Don't over mix. The mixture looks lumpy its fine.
Pour the mix into the prepared cake tin.
Bake at 180 degrees for 15 minutes
Check with a skewer. If the skewer comes out clean the cake is done.
Remove and thaw the cake.
Decorate as per choice.
I did spread a table spoon of mixed berry jam and sprinkled with icing sugar. To top it off used some dried rose buds.
