Banana Blueberry Cake

Get

200g organic macadamias
9 ripe bananas (more if small)
3 tbsp honey
1 tsp ground cinnamon
5 eggs separated
180g unsalted butter
about 100g flour
5 tsp baking powder (no aluminium or phosphate, quantity depends on the type of baking powder, do not use too much)

Do

Peel the bananas, cut them up.
Whip the egg whites until stiff, then add 1 tbsp honey and continue beating until stiff.
Beat the butter in a large bowl with a mixer until it is soft. Beat in alternately the egg yolks and 2 tbsp honey.
Beat well into a soft mixture.
Mix in half the banana pieces.
Grate the macadamias coarsely. Beat them into the mixture.
Add the cinnamon.
Add the flour a tablespoon at a time while beating. Alternately add the baking powder so it mixes in evenly. Only use enough flour so that the mixture is thick but still falls slowly - “heavily” - from the spoon (maybe only 3-4 tbsps). Beat well.
Lift the egg whites under the mixture. 

Preheat the oven to 190°. Butter a baking form and dust it with a little flour.
Add half of the mixture to the form and spread it evenly to cover the whole bottom. Place the remaining banana pieces on top and press in a little. Cover with the remaining mixture.
Sprinkle some fresh blueberries on top.
Bake on the 2nd shelf from the bottom for 40 minutes. If it starts to get too brown cover it with paper after 25 minutes. It should be golden. Test with a thin knife that it is cooked. The knife should come out clean. If it is not clean, return covered to the oven for another 10 minutes and test again.
Remove from form and cool.
Store in a glass dome.
