Preheat the oven to 350°F. Lightly grease a 9x13-inch baking pan.

In a small bowl or glass measuring cup, mash three medium ripe bananas with a fork. This should yield one cup of mashed banana.

In a large bowl, stir together the wet ingredients (brown sugar, sugar, coconut oil, melted plant based butter, vanilla extract, and mashed banana)

Mix until completely combined.

In a separate large bowl mix together the dry ingredients (flour, baking powder, salt).

Then pour the wet ingredients into the dry ingredients. Stir just until all the flour is mixed in. Then gently fold in the chopped pecans until evenly distributed in the batter.

Spread the batter evenly in the prepared pan and bake for 40 minutes, or until the top is golden and a toothpick inserted in the center comes out mostly clean.

Allow the pecan bread to cool in the pan for 15 to 20 minutes, then slice into squares or bars.
