Fold wet ingredients into dry ingredients just until combined. Grease and line a 9 x 5 baking pan with parchment paper. Pour the batter into the prepared pan. Sprinkle with chocolate chips. Bake for 45 minutes or until a toothpick inserted into the center of the cakes comes out clean. Remove from oven. Allow bread to cool for 10 minutes. Remove from pan. Cool completely. 12 servings.
