Beat sugar and softened butter until combined and fluffy.
Add mashed bananas, eggs, and yogurt and beat until combined.
Add the flour, baking soda, and salt. Combine until just moist.
Melt the chocolate chips in a bowl until just melted, about 1 minute. Stir together and then let cool slightly.
Add 1 cup of the batter to the chocolate and stir until combined.
In a greased bread pan, spoon the chocolate batter and the plain batter together one spoonful at a time, alternating the flavors. Swirl together with a knife.
Bake for about 1 hour and 15 minutes (until a wooden toothpick comes out clean).
Cool and enjoy!
