Ingredients
2 large ripe bananas, mashed
1½ cups rolled oats
½ cup oat flour or blended oats
2 large eggs
½ cup plain Greek yogurt
¼ cup milk (dairy or plant-based)
¼ cup honey or maple syrup
1 scoop (about 30g) vanilla or unflavored protein powder

1 tsp baking powder

Instructions
Preheat oven to 180°C (350°F) and line a small baking pan with parchment paper.
Mash bananas in a large bowl until smooth with a few small lumps remaining.
Add eggs, yogurt, milk, honey, and vanilla extract. Whisk until fully combined.

Mix gently until a thick batter forms.
Fold in nuts or chocolate chips if using.
Spread batter evenly into the prepared pan, smoothing the top with a spatula.
Tap the pan lightly to remove air pockets.
Bake for 25–30 minutes or until the center is set and lightly golden.
Cool completely before slicing into squares for clean edges.
Tips
Use very ripe bananas for natural sweetness and moisture.
If batter seems thick, add a tablespoon of milk to loosen it.
Do not overmix once dry ingredients are added to keep texture soft.
Line the pan fully with parchment to make lifting easier.
Allow squares to cool before cutting to prevent crumbling.
Choose a protein powder with a flavor you enjoy since it affects taste.
Toast nuts lightly beforehand for extra crunch and flavor.
Add a pinch of nutmeg or cardamom for a warm spice note.
Store in an airtight container to maintain freshness.
Warm briefly in the microwave before serving for a fresh-baked feel.
Variations
Add blueberries or chopped strawberries for a fruity version.
Replace yogurt with mashed cottage cheese for extra protein.
Use peanut butter or almond butter instead of part of the yogurt for richness.
Make it vegan by using flax eggs and dairy-free yogurt.
Mix in shredded coconut for a tropical flavor.
Add pumpkin puree and pumpkin spice for a fall-inspired twist.
Include grated carrot and raisins for a carrot cake style square.
Swap cinnamon for cocoa powder to create a chocolate version.
