Peanut Butter Banana Bread

Ripe bananas and peanut butter make a loaf that tastes familiar, just with a nuttier edge. Chocolate chunks melt into the bread and the thick glaze adds a sweet finish on top.

Ingredients

For the Bread

For the Glaze

Instructions

  • Preheat the oven to 350°F. Grease a 9x5 loaf pan or line with parchment paper.

Make the Batter

  • In a large bowl, whisk together the melted butter, peanut butter, brown sugar, and granulated sugar until smooth.
  • Add the eggs, mashed bananas, sour cream, and vanilla extract and mix until fully combined.
  • In another bowl, whisk together the flour, baking soda, and salt.
  • Add the dry ingredients to the wet ingredients and stir until just combined.
  • Fold in the chocolate chips or chunks.

Bake the Banana Bread

  • Pour the batter into the prepared loaf pan and spread evenly.
  • Bake for 55 to 65 minutes until a toothpick inserted in the center comes out mostly clean.
  • Let cool in the pan for 20 minutes, then transfer to a wire rack to cool completely.

Add the Glaze

  • In a bowl, whisk together the peanut butter, powdered sugar, and milk until smooth and pourable.
  • Drizzle the glaze over the fully cooled bread.

Notes

Choose bananas with plenty of brown spots: Very ripe fruit mashes easily and adds a stronger banana taste.
Let the butter cool slightly: Hot melted butter can make the peanut butter mixture greasy.
Measure the flour lightly: Spoon flour into the measuring cup and level the top. Scooping directly from the bag can add too much.
Stop stirring when the flour disappears: Extra mixing can make the loaf dense.
Add the milk gradually: Start with a small amount and add more in small splashes until the glaze falls from your whisk in thick ribbons.
Glaze when cool: Warm bread thins the glaze and makes it run down the sides.
Cover a darkening crust: Place foil loosely on top if the crust browns before the center is ready. Also, I like to use a light-colored nonstick loaf pan for even baking.
