Prep Time 15 minutes
Cook Time 1 hour
Total Time 1 hour 15 minutes
Servings 8 servings


  • 1/2 cup semisweet chocolate chips
  • 2 cups all-purpose flour
  • 3/4 cup sugar
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 very ripe, darkly speckled bananas, mashed well (about 1 ½ cups)
  • 1/4 cup sour cream
  • 2 large eggs, beaten lightly
  • 1/4 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 3/4 cup peanut butter chips, divided


  • Preheat the oven to 350°F. Line a 9-inch loaf pan with parchment paper then grease the parchment paper with cooking spray.
  • Add the chocolate chips to a small microwave-safe bowl then microwave them for 30-second intervals, stirring between each interval, until the chocolate is melted. Set it aside.
  • In a large bowl, whisk together the flour, sugar, baking soda and salt.
  • In a separate medium bowl, whisk together the mashed bananas, sour cream, eggs, vegetable oil and vanilla extract. 
  • Add the wet ingredients to the dry ingredients and stir just until combined. 
  • Transfer 1 cup of the batter to a separate bowl and stir in the melted chocolate.
  • Stir in ½ cup of peanut butter chips to the plain banana bread batter then alternately drop dollops of both the plain and chocolate batters into the prepared loaf pan.
  • Using a knife, swirl the batters together then top the loaf with the remaining ¼ cup peanut butter chips.
  • Bake the bread for 45 minutes then cover it with foil and bake it an additional 15 minutes or until a toothpick inserted comes out clean.
  • Remove the bread from the oven and allow it to cool completely in the loaf pan before slicing and serving.
