Preheat oven to 375 F
Mix olive oil and white sugar together. Add in eggs. Add in bananas, Balsamic vinegar and vanilla.
Add in spices, salt and baking powder + soda, mix and then follow with the flour, progressively.
Mix until almost all combined then stop and fold the remainder of the mixture to avoid over mixing.
While your oven finishes preheating, prepare your loaf pan with butter and flour. (Spread the butter thinly with your fingers in the pan all around and all the way to the top. Then add 1 tbsp flour into the pan, place yourself above the sink and tap each side of the pan while rotating it to evenly coat all sides with flour, turn over the pan to discard the rest of the flour). Alternately, use parchment paper as suggested in the post.
Carefully pour in batter, cook in the middle of the oven for 50-60 minutes. To check if your banana bread is ready, stick a toothpick right in the middle of it. If it comes out clean, your cake is ready. If not, bake a little longer.
Once ready, take your banana bread out of the oven and set it on a cooling rack for 10-15 minutes. Slice and serve with hot steamy cup of joe. Enjoy!
