Preheat your oven to 350°F (175°C) and grease a standard 9x5 inch loaf pan.

Mash the bananas with a fork until smooth with some lumps, then mix in melted butter and eggs until combined.

Sift together flour, baking soda, salt, and cinnamon in a separate bowl.

Fold dry ingredients into the wet banana mixture until just mixed without overmixing.

Pour half the batter into the pan, drizzle caramel, then add remaining batter and swirl caramel into it.

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

Cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
