Prepare the Oven
Preheat your oven to 350°F (180°C). Line a 9 x 5 inch loaf pan with parchment paper to prevent sticking and make removal easier.Mash the Bananas
In a large mixing bowl, mash the ripe bananas until smooth. Stir in the fresh lemon juice to enhance the flavor and help preserve the color.Mix the Wet Ingredients
Add the eggs, peanut butter, maple syrup, vanilla extract, and milk to the mashed bananas. Mix everything together until smooth and well combined.Combine the Dry Ingredients
In another bowl, whisk together the oat flour, baking powder, cinnamon, and salt until evenly mixed.Make the Batter
Add the dry ingredients to the wet mixture. Stir gently until everything is just combined. Avoid overmixing, as this can make the bread dense.Add Chocolate Chips
Fold in the mini chocolate chips, nuts, or raisins if desired. This step adds texture and extra sweetness to the bread.Bake the Banana Bread
Pour the batter into the prepared loaf pan and spread it evenly. Bake for 50 to 60 minutes, or until a toothpick inserted in the center comes out clean or with only a few crumbs.Cool the Bread
Allow the banana bread to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely before slicing.
