Preheat the oven to 350 degrees.
Toast pecans in the oven on a cookie sheet for 3-5 minutes at 350*.
Spray loaf pan with pam cooking spray. Add in a sheet of parchment paper. Then spray the parchment paper with a little bit of cooking spray as well.
Peel the bananas and place them into a large mixing bowl. Using a potato masher or pastry cutter, mash the bananas until they are a liquid batter, but will still have lumps. We don't want any big pieces of bananas left, but small chunks are fine!
Add in the eggs and vanilla extract and mix well with whisk.
Add in the yogurt and melted butter and mix well with whisk.
Next add in the brown sugar and mix well.
Add in the self-rising flour and mix slowly to avoid spilling flour everywhere. This will be a thick batter once all the flour is incorporated.
Add in the toasted pecans and stir with a spatula to mix in all the pecans throughout the batter.
Pour batter into prepared loaf pan and smooth the top of the batter.
Bake in the oven at 350* for 55-65 minutes. If the top gets too brown before the loaf is done, place aluminum foil loosely over the top of the pan.
Let cool for 10-15 minutes, remove loaf from pan and enjoy!
Store in an airtight container at room temperature for up to 5 days.
