Marbled Chocolate Banana Bread

2 cups flour
¾ tsp baking soda
½ tsp salt
1 cup sugar
¼ cup butter, softened
1 ½ cups mashed ripe banana (about 3 bananas)
½ cup egg substitute
1/3 cup plain low-fat yogurt
½ cup semisweet chocolate chips
Cooking spray


Preheat oven to 350 degrees. Lightly spoon flour into dry measuring cups, and level with a knife. Combine the flour, baking soda, and salt, stirring with a whisk. Beat butter and sugar in large bowl at medium speed until well blended (about 1 minute). Add banana, egg substitute, and yogurt; beat until blended. Add flour mixture; beat at low speed just until moist. Microwave chocolate chips on high 1 minute or until almost melted, stirring until smooth. Cool slightly. Add 1 cup batter to chocolate, stirring until well combined. Spoon chocolate batter alternatively with plain batter into an 8 ½ X 4 ½-inch loaf pan coated with cooking spray. Swirl batters together using a knife. Bake at 3500 for 1 hour and 15 minutes or until a wooden pick inserted in center comes out clean. Cool 10 minutes in pan on a wire rack; remove from pan.
