3 medium-to-large very ripe bananas, mashed
½ cup butter, melted
¾ cup dark brown sugar
1 large egg
1 teaspoon pure vanilla extract
1 teaspoon baking soda
¼ teaspoon table salt
1 cup all-purpose flour
½ cup Dutch-process cocoa powder
1 cup semisweet or bittersweet chocolate chunks or chips
Preheat the oven to 350° F.
Place bananas in a large bowl. Whisk in melted butter, then brown sugar, egg and vanilla. In a medium mixing bowl, combine baking soda, salt, flour and cocoa powder. Sift over wet ingredients. Stir dry and wet ingredients with a spoon until just combined. Stir in chocolate chunks or chips.
Pour into greased 9" x 5" loaf pan and bake 55 to 65 minutes, until a tester or toothpick inserted into the center of the cake comes out batter-free. Cool in pan for 10 to 15 minutes, then run a knife around edge and invert loaf out onto a cooling rack. Serve warm or at room temperature.
Note: The banana bread will keep for up to 4 days at room temperature, wrapped in foil.
Yield: One loaf
