Healthy Banana Bread with Chocolate Swirl

1. Preheat oven to 350°F. Lightly grease 8½ x 4½ x 2½-inch pan.
2. In a medium-sized bowl or food processor, whisk together eggs, sugar, yogurt, and oil. Stir in mashed banana and vanilla.
3. In a large bowl, combine flour, baking powder, baking soda and salt.
4. Add banana mixture to flour mixture and stir to combine.
5. Place chocolate chips and milk in 2 or 4-cup measure, or in a microwave-safe bowl. Heat on high for 30-50 seconds (until chocolate just starts to melt). Remove from microwave and stir until smooth.
6. Add 1 cup of batter to chocolate mixture, and stir until combined. Place alternating spoonfuls of chocolate and plain batters into the loaf pan. With a knife, swirl batters together.
7. Bake bread until golden brown on top and tester inserted into center comes out clean (about 1 hour). Remove from pan and cool on rack.
