Preheat the oven to 375 degrees F. Coat a mini loaf pan or standard 9x5-inch loaf pan with nonstick spray.
In a large bowl, stir together the yogurt, banana, maple syrup, peanut butter, eggs, and vanilla.
Add the flour, baking powder, baking soda, cinnamon, and salt.
Gently stir the yogurt mixture into the flour mixture.
Pour batter into the prepared pan.
Bake for 26-28 minutes if using a mini loaf pan or until the edges are lightly golden brown and a cake tester inserted into the center comes out clean. Let cool for 5 minutes in the pan, then remove from pan and cool completely on a wire rack before slicing.
To make in a standard 9x5-inch baking loaf pan, reduce the oven temperature to 350 degrees F and bake for 55-60 minutes. Towards the end of baking, if the bread is browning a lot on top, cover with foil and continue baking.
