Peel and roughly dice the bananas. Cream fat, vanilla sugar and sugar with the whisk of the hand mixer. Stir in the eggs one by one. Stir in honey. Mix flour and baking powder and stir in alternately with 100 ml milk. Fold in mashed bananas.
Cut the dough in half, stir in one half cocoa and 3-4 tbsp milk. Pour both doughs into two greased springform pans (each approx. 24 cm Ø) sprinkled with flour, smooth them down and bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 20 minutes. Remove the bases from the oven and let them cool down for about 15 minutes. Remove the cake bases from the edge of the springform pan, let them cool down and remove them from the tins. Cut or cut out a circle (approx. 10 cm Ø) from the middle of each cake base. Remove the circle. Cut out or cut out a larger circle (ring, approx. 18 cm) from the remaining cakes. Whip the double cream, lemon zest and icing sugar to a spreadable cream. Reassemble the cake bases, but replace the middle dark ring with the light one. Spread some cream on one base. Place the upper cake base on top. Spread cream all around the cake, refrigerate for about 1 hour.
