Grease a medium loaf pan and sprinkle the sesame seeds evenly on the bottom of the pan.
Beat the butter or margarine in a large mixing bowl. Add the brown sugar and beat until creamy.
Add the eggs, one at a time, beating after each addition. Beat in vanilla extract. Set aside.
In a medium bowl, mix the flour, baking powder, baking soda, and salt.
Add about a third of the dry mixture to the butter mixture and stir well. Add half the banana and stir.
Add another third of flour, and the rest of the banana, and stir until incorporated.
Add the remaining third of flour and the yogurt. Mix well until combined.
Stir in the chocolate chips.
Scrape the batter into the prepared pan and spread evenly. Bake for 60 to 70 minutes or until a wooden skewer inserted into the centre comes out clean.
Let loaf cool for about 10 minutes before turning out onto a wire rack to cool completely before slicing.
