Step 1

HEAT OVEN TO 350F: Crumple a parchment paper into a ball. Smooth it out and line a 9 x 5 inch (23x13 cm) or 4 x 8 inch (20xloaf pan.

Step 2

BOWL #1 (small bowl): Mix together mashed bananas, yogurt and baking soda with a fork or spoon.

Step 3

BOWL #2 (medium bowl or 2 cup measuring cup): Stir together flour, baking powder and salt (if using).

Step 4

BOWL #3 (large bowl): Use a spoon or whisk to mix butter and brown sugar together until well combined. Add egg and vanilla and whisk until smooth and creamy. Add banana-yogurt mixture and mix well. Add flour mix in 3 parts, mixing lightly between each addition. DO NOT over mix. Just mix until flour is incorporated. Batter will be thick. Stir in optional add-in if using.

Step 5

BAKE: Spoon batter into parchment-lined loaf pan. Bake for 50-60 minutes or until cake tester or toothpick comes out clean. Using a smaller loaf pan may take a bit longer. Start checking after 50-55 minutes. The middle may still be wet. Bake another 3-5 minutes and check again. When done, remove pan from oven and let cool. Lift banana bread out by holding onto sides of parchment.
