Banana-Peanut-Marmelade Cake (aka Marilyn Monroe Cake)

I got the idea to make this make when I ate an insanely tasty bagel in one of my favourite cafés in Berlin - Miss Ploff in Wedding. It was called 'Elvis-Presley' and I just though the combination of banana, peanut-butter and marmalade fitted perfectly. So today I decided to dedicate the Elvis-

Presley Bagel a cake which I'm gonna call 'Marylin Monroe'!      

Ingredients (for a loaf pan):

For the banana bread:

3 mashed bananas
200g flour
80g brown sugar
100g grounded almonds
1 egg
1 pinch of salt
1 sachet of baking powder (15g)
5 tablespoons of neutral oil (I used sunflower oil)
1/2 sachet of vanilla sugar
1/2 teaspoon of cinnamon (or more)
vanilla extract

for the filling:

150g cream cheese (I used low fat)
170g creamy peanut-butter
50g powdered sugar
2-3 tablespoons of milk
vanilla extract

100g strawberry marmalade

for the topping:

50g peanut-butter
chocolate chips
salted peanuts

For the banana bread, mix the dry ingredients and add the wet ingredients. Fill the dough into a loaf-pan and bake for around 45 minutes (180°C). Let it cool down completely and take it out of the form. (I did it the evening before).

For the filling, mix peanut-butter, cream cheese and powdered sugar until smooth (the more milk you add, the more smooth it gets).

Cut the cake horizontally into 3 layers. Spread the filling on the 1st layer and add the 2nd layer. Spread marmalade on the 2nd layer and add the top. Heat the peanut-butter until liquid and let it drip on the cake. Sprinkle choco chips and salted peanuts on top.
