Preheat oven to 375 degrees.

In a large bowl, add room temperature butter and start mixing. Slowly add in the sugar and continue mixing. Then add the eggs and keep mixing. Next come the ripe bananas, vanilla extract, baking soda, and baking powder.. When this mixture is thoroughly combined, slowly add in the flour, mixing continuously.

In a parchment paper-lined (preferably brushed with some butter) bread pan, pour the banana bread mixture. Tap it down a few times to even out the dough.

Cook in oven for 50-55 minutes and when a toothpick comes out clean.

Serve warm or room temperature.
