Preheat your oven to 400 degrees F. Grease your pan with vegetable shortening or baking spray.
In a medium mixing bowl, whisk together the mashed bananas, vegetable oil or butter, buttermilk, maple syrup, brown sugar, eggs, and vanilla until everything is homogenous and smooth.
2 overripe bananas, 2 tablespoon vegetable oil, 1 cup buttermilk, ¼ cup maple syrup, ⅓ cup brown sugar, 2 large eggs, 2 teaspoon vanilla extract
In a separate large bowl, whisk together the cornmeal, flour, baking soda, baking powder, cinnamon, and salt.
1 cup coarse cornmeal, 1 cup all purpose flour, 1 teaspoon baking powder, 1 teaspoon baking soda, 2 teaspoon ground cinnamon, ½ teaspoon kosher salt
Pour the wet ingredients into the bowl of dry ingredients and use a silicone baking spatula to mix everything together until it becomes just combined. Don't overmix.
Pour the batter into the prepared pan, then sprinkle the pecans all over the top.
½ cup roasted pecans
Bake the maple banana cornbread for 25-30 minutes, until a toothpick or cake tester poked in the center comes out clean with a few crumbs.
Let the cornbread cool for 15-30 minutes, then remove from the pan and let it cool completely on a wire rack until room temperature.
Slice and serve with softened butter or a cup of milk! Keep on the counter in an airtight container for 3 days.
