Peel the bananas, cut them up roughly and puree them finely. Mix 150 g butter, 150 g sugar and salt with the whisk of the hand mixer until creamy. Stir in the eggs one after the other. Mix starch, flour, ground almonds and baking powder and stir in alternately with the banana puree.
Put the dough into a greased, flour-dusted saddle of venison dish (11 x 30 cm, approx. 1 litre capacity) and smooth it down. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 35 minutes.
Take out and let cool on a cake rack. Carefully turn out of the mould and let it cool down.
Caramelise 75 g sugar in a pot. Add 25 g butter and mix. Add cream and simmer gently until the caramel has dissolved. Remove from the heat and let it cool down while stirring occasionally.
Put the saddle of venison on a cake plate. Mix caramel sauce with salted almonds and spread on the cake.
