Icing:

7 dates

2 soup spoons peanut butter 

150 grams cream cheese ( I combined it with Greek yoghurt.)

1. Mix almonds with oat flakes together. Add  dates or raisins and mix them until ingredients are united. you can add water or almond (or other) milk, if dough is crumbly.  

2.Stuff dough into cake mould.    

3 Give cut or mashed bananas (I combined them with juniper) on the dough.

4.Prepare icing by mixing cream cheese with dates and peanut butter together. (I added honey because I like sweets)
