Put 2 bananas in a blender together with a teaspoon of vanilla syrup and oat milk and blend.
In a bowl add the dry remaining ingredients. Mix everything well.
Now add the liquid ingredients to the dry ingredients.
Grease a small loaf pan (mine measured 18.5 cm (length) × 5 cm (height) × 12.5 cm (width)) with a little oil and add the dough. Place 1/2 banana on top (optional).
