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.
3 bananas
Add the eggs, maple syrup, vegetable oil, vanilla, and yogurt to the mashed ripe bananas. Whisk vigorously until everything is well incorporated.
2 eggs, ½ cup maple syrup, ⅓ cup vegetable oil, 1 teaspoon vanilla extract, ½ cup Greek yogurt
In a separate mixing bowl, combine the all purpose flour, baking powder, baking soda, and salt. Whisk until evenly distributed.
2 cups all purpose flour, 1 teaspoon baking powder, 1 teaspoon baking soda, ½ teaspoon salt
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.
1 tablespoon chia seeds
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.
