Take the remaining tablespoon of butter and use a 9 x 5 -inch nut pan to cover it with a paper towel to the lower and sides. Align the pan with parchment paper: a piece of parchment paper, use a little narrower than the width of the nut pan and place it under the ceiling and fold extra on the edges (if necessary). This will help when you remove the nut later.
Cook a toothpick or cake test device placed at the center of the banana bread until it is clean for 50 minutes to 1 hour. Allow to cool completely and about 1 to 2 hours before cutting. Serve and serve.
