Preheat the oven to 350°F and grease a loaf pan or line it with parchment paper.
In a large bowl, mash the bananas with a fork or potato masher until no large pieces remain. Some clumps are ok.
Add the eggs, maple syrup, vegetable oil, vanilla, and yogurt to the mashed ripe bananas. Whisk vigorously until everything is well incorporated.
In a separate mixing bowl, combine the all purpose flour, baking powder, baking soda, and salt. Whisk until evenly distributed.
Pour the dry ingredients into the wet and fold with a rubber spatula until the batter is about 90% combined. Then, gently fold in the chia seeds until no dry streaks of flour are left.
Pour the batter into the prepared loaf pan, smooth out the top, and sprinkle with additional chia seeds. Bake for 45-50 minutes or until a toothpick inserted in the center comes out clean.
Let the bread cool in the pan for 10 minutes. Transfer to a wire cooling rack, let cool completely, slice, and enjoy.
