Preheat oven to 350 degrees. Lightly coat the inside of 3 mini loaf pans with non-stick cooking spray. (I used loaf pans that were 8x4x3") Alternatively, you can use a bundt pan.
In a large mixing bowl, use a hand-held mixer to beat together the butter and sugar until light and fluffy.
Add the vanilla and eggs and beat into the butter and sugar mixture.
Next, add the mashed bananas and Greek yogurt. Beat until well incorporated.
Add the flour, baking soda, and salt. Beat until the flour is just mixed into the wet ingredients.
Add the chocolate chips and pecans. Fold into the batter with a spatula.
Evenly distribute the batter among the 3 prepared loaf pans. Tap each pan firmly on your counter top to settle the batter into the pan.
Optional: top each loaf with a few chocolate chips and pecans.
Bake for 30 minutes. Remove from oven and allow to cool for 5 minutes before removing from the loaf pan to cool completely on a wire cooling rack.
Notes
Each serving size is a 1 inch slice across the loaf.
