Sift together the flour, baking powder, baking soda and salt. In a separate bowl, add the mashed banana, brown sugar, yogurt, eggs and vanilla essence. Combine everything and add the crushed dry fruits. Mix well.
Gently fold in the sifted flour and transfer the contents to a greased loaf tin. Bake in a preheated microwave oven for 40 minutes.
Remove the tin on a wire rack and set aside to cool for 30 minutes. Flip it over on the rack and let it cool further.
Slice it according to desired thickness and enjoy as a dessert topped with your favourite ice-cream or with your evening cup of tea.
