Preheat oven to 350 degrees. Coat a 9″ loaf pan with cooking spray and set aside.
In a large bowl, stir butter and 3/4 cup of the brown sugar together until thoroughly combined. Next, add eggs, yogurt, banana and vanilla and stir until combined. Add 1 teaspoon cinnamon, nutmeg, flour, baking soda, salt and dry pudding mix and stir until just combined. You don’t want to over mix. The batter will be thick and lumpy. Spread batter into the prepared pan.
In a small bowl, combine the remaining brown sugar and cinnamon. Sprinkle the mixture on top of the banana bread, then slightly push topping into batter.
Bake the bread for 30 minutes, then loosely tent with foil to prevent the crust from burning. Bake for an additional 30 minutes.
Allow the bread to cool completely before cutting into slices.
