Preheat oven to 350℉ and line a loaf pan with parchment paper.
In a bowl, combine all of the banana bread ingredients until you have a smooth batter.
In a separate bowl, mix together the coffee swirl ingredients. Spread half of the banana bread batter into the prepared pan, sprinkle the coffee swirl evenly over top and use a toothpick or butter knife to swirl it in. Add the remaining banana bread batter on top.
Bake for about 45-50 minutes, or until a toothpick comes out clean. Let cool completely before slicing and enjoying!
