Double Chocolate Banana Bread
This chocolate banana bread is a decadent reinvention of the classic. It doubles down on the fudgy richness with two forms of chocolate: bold, Double Dark Cocoa Blend adds bittersweet flavor and lends a strikingly dark color, while a scatter of mini chocolate chips creates pockets of sweetness. Sour cream steps in as the unexpected hero, adding a subtle tang that balances the sweetness and keeps the crumb tender and moist.
