  • ½ stick unsalted butter melted
  • cup peanut butter
  • ¾ cup sugar
  • 2 eggs room temperature
  • 3 bananas mashed
  • cup buttermilk
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 ¾ cup all purpose flour


  • Preheat the oven to 350F. Coat a 9x5 loaf pan with cooking spray and line with a parchment paper. 
  • In a large bowl, mix melted unsalted butter, peanut butter and sugar until creamy. 
  • Add in eggs one by one, mixing well after each addition. 
  • Mix in mashed bananas. 
  • Add butter milk and stir well. 
  • Add in baking powder, baking soda, salt and all purpose flour. Mix using a wooden spoon until well combined. Don't over mix the batter. 
  • Pour the batter into the loaf pan and bake for 45-50 minutes until a toothpick inserted in the middle comes out clean or with very few crumbs. 
  • Let the peanut butter banana bread cool completely before slicing. 


  • To make butter milk, mix ⅓ cup milk with ½ tablespoon lemon juice or vinegar. You can also use Greek yogurt instead of buttermilk. 
  • The riper the bananas, the moister the banana bread is going to be. Use bananas that are completely ripe and have brown spots all over them.
  • To make peanut butter chocolate chip banana bread add ¾ cup chocolate chips to the batter at the end and fold in gently.
  • You can use wither creamy or chunky peanut butter for this recipe. If using natural peanut butter, make sure you stir it completely before using.
  • Have all the ingredients at room temperature for better results.
  • Check the banana bread after 45 minutes of baking and if the top is brown but the middle is still doughy, cover with aluminum foil and bake for another 5-10 minutes.
