Preheat your oven to 350°F (175°C).
Do this first. Cold ovens ruin baked goods and moods.
Line a loaf pan with parchment paper.
Trust me. This saves emotional distress later.
Mash the bananas.
In a big bowl, mash until mostly smooth. Some lumps are fine. We’re baking, not doing science.
Add wet ingredients.
Mix in eggs, honey, oil, yogurt, and vanilla. Stir until smooth and glossy.
Mix dry ingredients.
In another bowl, combine oat flour, protein powder, baking powder, baking soda, cinnamon, and salt.
Combine wet and dry.
Gently fold dry into wet. Do not overmix. Overmixing = dense loaf sadness.
Add extras.
Fold in chocolate chips or nuts if using. Live your best life.
Pour into pan.
Smooth the top and tap the pan lightly to release air bubbles.
Bake for 45–55 minutes.
Bake until a toothpick comes out with a few moist crumbs.
Cool before slicing.
Wait at least 20 minutes. Cutting early is self-sabotage.
