Preheat your oven to 350°F (175°C) and grease a standard loaf pan.

In a large mixing bowl, cream together the butter and sugar until light and fluffy, then add the egg and bananas.

In a separate bowl, whisk together the flour, baking soda, and salt, then fold it into the banana mixture.

Mix together the melted butter, cinnamon, and brown sugar for the swirl.

Layer half of the banana batter, then half of the cinnamon mixture, repeat the process.

Gently swirl through the layers of batter.

Bake for about 55 minutes or until golden brown and a toothpick comes out clean.

Let the bread cool in the pan for 10 minutes, then transfer to a wire rack.

Prepare the cream cheese frosting by mixing the ingredients until smooth.

Once cool, frost the bread and slice it to serve.
