Ingredients:

2 overripe bananas (mashed into a smooth paste)
1/2 cup caster sugar
1 teaspoon  fennel seeds
1 egg
1 teaspoon vanilla extract
A pinch of cinnamon
1/2 to 1 cup of milk (whole or skim)
1 1/2 cups whole wheat flour
1 teaspoon baking powder
Vegetable oil for frying
 
Method:

Gather the ingredients.
In a large bowl, mix together the mashed bananas, sugar, fennel seeds, egg, vanilla essence, cinnamon, and milk. Stir to blend everything well, making sure the sugar dissolves completely.
Mix together the whole wheat flour and baking powder in a separate bowl.
Using a whisk, slowly and a little at a time, add the flour to the wet ingredients. Mix well to ensure there are no lumps or as few as you can manage. You want to end up with a batter that is really thick. You might need a little more flour to achieve this consistency.
