This recipe is from a German vegan forum I frequent.
It turned out delish, though it's another proof that I can't bake anything without having it fall apart. But it's good enough to share.
for the cake:
1/2 package baking powder
100 ml soy milk
100 ml oil (I used soy oil)
10 g soy flour
50 ml water
Mix all ingredients and fill in a greased cake pan (I used heart-shaped because that's all I've got, but a star or a simple round one would work as well).
Bake for 40 minutes at 180°C, let cool for 10 minutes and take out of the form.
Now bring 200g raspberries, 150 ml soymilk (I used strawberry-flavoured), 80g confectionary sugar, and a package Agartine/ 2 tbsp agar agar to a boil, constantly stirring.
Lower down the heat, but keep stiring for 2-5 minutes.
Pour into the cake pan.
While you wait for the filling to become solid, slice the cake in two halves horizontally (that's where huge parts of my heart came crumbling down :( ).
Now when totally solid, put the jelly part on the bottom part and top with the other part of the cake.
It's a bit tricky, but totally worth the effort.
Now melt 200-400 g nougat (microwave!), depending on the surface of the cake and ice the cake with it. When the nougat has cooled down a bit, springle with some more confectionary sugar.
This is best after you've allowed it to set in the fridge for a day or so.
