Preheat oven to 350 degrees.
Spray a 9x5 loaf pan with non-stick cooking spray or line with parchment paper, set aside.
In a small bowl mash bananas, set aside.
In the bowl of an electric mixer (or large mixing bowl for a hand mixer) add dark brown sugar and vegetable oil. Mix for 2 minutes.
Add in eggs, 1 teaspoon maple extract and vanilla extract and mix until combine, about 1 minute.
In a medium sized mixing bowl add flour, baking soda, cinnamon, grated nutmeg and kosher salt. Whisk to combine.
Add half the flour mixture to the sugar mixture and mix just until combined.
Add half the mashed bananas and mix just until combined.
Repeat the last 2 steps.
Fold in shredded carrots and gently mix until combined.
Bake for 60-70 minutes or until the center of the bread is fully cooked. Test this by putting a toothpick in the center of the cake and if it comes out clean the bread is fully cooked.
Once the bread is fully baked let it rest for 10 minutes, carefully remove from the pan and let cool.
In a mixing bowl add cream cheese, powdered sugar, remaining maple extract and vanilla bean paste.
Mix until light and fluffy. If the mixture is too thin add more powdered sugar and if it's too thick add a teaspoon of milk.
Spread the frosting on top of the bread and sprinkle with chopped pecans.
