5 from 5 reviews

This Cookie Butter Banana Bread combines moist, overripe bananas with rich, creamy cookie butter swirled through the batter for irresistible bursts of flavor. The addition of sour cream creates an ultra-tender crumb while traditional baking soda and powder give it just the right lift. It’s easy to make and perfect for breakfast, dessert, or sharing with friends.

  • Total Time: 1 hour 15 minutes
  • Yield: 8-10 Slices 1x

Ingredients

Units Scale
  • 200 grams (1 Cup) Granulated Sugar
  • 4oz (1/2 Cup) Unsalted Butter, melted
  • 2 Large Eggs, at room temperature
  • 2 Teaspoons Pure Vanilla Extract
  • 6oz (3/4 Cup) Cookie Butter, divided
  • 250 grams (2 Cups) All-Purpose Flour
  • 1/2 Teaspoon Salt
  • 1 Teaspoon Baking Soda
  • 1/4 Teaspoon Baking Powder
  • 3 Large Ripe Bananas, spottier the better
  • 4oz (1/2 Cup) Sour Cream or Full-Fat Greek Yogurt

Instructions

  1. Preheat the oven to 350F/180C and spray a 9X5 loaf pan with nonstick cooking spray or butter the pan.
  2. In a large bowl combine the melted butter, sugar, eggs, vanilla extract, and 1/4 cup (2oz) of the cookie butter. Whisk until fully combined.
  3. Add the ripe bananas and use a potato masher or fork to mash the bananas down. Then mix in sour cream. 
  4. Add flour, salt, baking soda, and baking powder then mix until just combined. Do not overmix.
  5. Pour half of the batter into the prepared pan then spoon half of the remaining cookie butter on top of the batter and use a knife to swirl it. Top with remaining batter and repeat swirling of remaining cookie butter.  
  6. Bake for 55-65 minutes, or until fully cooked- you can check by inserting a knife and looking for any wet batter. If you use an internal thermometer the temperature should reach 200F-205F. Let cool completely before slicing, and store leftovers in an airtight container for up to 5 days in a cool environment.
