Mash the bananas
In a large bowl, mash 3 ripe bananas until mostly smooth. A few small lumps are perfect—they add texture and extra banana flavor.
Whisk the wet ingredients
Add:
2 eggs
1/2 cup Greek yogurt
1/4 cup maple syrup or honey
1 tsp vanilla
Whisk until silky and well combined.
Add the dry ingredients
Sprinkle in:
1 1/2 cups oat flour
1 scoop protein powder
1 tsp baking soda
1 tsp baking powder
1/2 tsp salt
1–1 1/2 tsp cinnamon
Fold gently
Use a spatula to fold until just combined.
This step is key for moist high protein banana bread—overmixing can make it dense.
Stir in add-ins (optional)
Fold in:
chocolate chips
walnuts
blueberries
chia or flax
Keep it light and minimal—your loaf will thank you.
Bake
Pour the batter into the pan and smooth the top.
Bake for 45–60 minutes, depending on your oven and protein powder.
Check for doneness
Your banana bread with protein powder is ready when:
the top looks set and lightly golden
a toothpick comes out with a few moist crumbs
the center springs back gently when pressed
Cool before slicing
Let the loaf cool in the pan for 10–15 minutes, then transfer to a rack.
Wait another 20–30 minutes before slicing for the cleanest, tender crumb.
