Best banana bread recipe (sugar free)

From all the banana bread recipes I've tried so far, this one was definitely the best (and the most appreciated). It needs just 5-10 minutes to prepare and about 1h to bake. 

Ingredients:
- 3 medium bananas, very ripe, mashed;
- 2 eggs;
- 1/2 cup milk;
- 7 Tbsp oil;
- 1 tsp baking soda;
- seeds of a vanilla bean or 1/2 tsp vanilla powder;
- 1/2 tsp cinnamon;
- 1 3/4 cups white flour;
- a handful of walnuts, ground, or chopped (minimum 50g).
* this recipe does not contain sugar, the bananas are usually tasty enough. If you like concentrated sweets and you have no restrictions, you can add 2-3 Tbsp of honey or another sweetener of your choice.

Method:
In a bowl (or in the blender), mix the mashed bananas, eggs, oil, milk, vanilla, cinnamon and (if using) sweetener. Separately, mix the flour, baking soda and ground walnuts. Add the dry ingredients over the liquid mix and stir until smooth. Pour in a loaf pan lined with baking paper and bake in the preheated oven (180 degrees Celsius), for about 50 minutes - one hour, until it passes the toothpic test. Let it cool in the tray for at least 15 minutes and cut only when completely cooled.
Enjoy!
