Method
Preparation
- Preheat the oven to 350°F (180°C) and grease a 9x5 loaf pan.
- In a large bowl, combine the melted butter, sugar, eggs, vanilla extract, and 1/4 cup (2oz) of the cookie butter. Whisk until smooth.
- Add the ripe bananas and mash them with a potato masher or fork. Stir in the sour cream.
Mixing Ingredients
- Sprinkle in the flour, salt, baking soda, and baking powder. Mix until just combined—avoid overmixing.
Layering and Baking
- Pour half of the batter into the prepared pan. Spoon half of the remaining cookie butter on top and swirl with a knife.
- Layer the remaining batter and repeat the swirling with the last bit of cookie butter.
- Bake for 55-65 minutes until golden and a knife comes out clean.
- Let cool completely before slicing.
Notes
Store leftovers in an airtight container for up to 5 days. For extra decadence, fold in chocolate chips or walnuts. For variations, consider spices like cinnamon or nutmeg.
