Preheat the oven to 350°F and grease a muffin pan with butter or nonstick cooking spray.
In a medium bowl, toss together the flour, protein powder, baking powder, and pinch of salt.
1½ cups whole wheat flour, ½ cup protein powder, 2 tsp baking powder
In a large bowl, mash the banana. Add the eggs, yogurt, coconut sugar, olive oil, and vanilla. Whisk until combined.
1 ripe banana, 2 large eggs, 1 cup Greek yogurt, ½ cup coconut sugar, 3 tbsp olive oil, 1 tsp vanilla extract
Add the dry ingredients to the wet ingredients and mix until just combined. Fold in the strawberries.
1 cup strawberries
Evenly spoon the batter into the muffin pan. Top with sliced strawberries if desired. Bake for 20–25 minutes or until a toothpick inserted into the center comes out clean.
Notes
Store the muffins in an airtight container at room temperature for up to a day. After that, they should be stored in the fridge because of how moist they are. They can be kept in the fridge for up to 5 days. Reheat in the toaster oven (350F) or air fryer (325F) for 5 minutes.
