Naturally sweetened with ripe bananas, these protein brownies are irresistibly moist and rich, offering a decadent treat without the guilt. Packed with 15 grams of high-quality protein per serving, they make a perfect post-workout snack or a satisfying midday pick-me-up that fuels your muscles and keeps you energized. The tender crumb melts in your mouth, while the subtle banana flavor adds a natural sweetness and depth to every bite. With a balanced macro profile, they’re ideal for those looking to increase their protein intake while enjoying a delicious dessert or snack. The recipe is versatile and can be easily adapted to gluten-free diets by using almond or coconut flour, and vegan options are simple with plant-based protein powders and flax eggs. For best results, use very ripe bananas for maximum sweetness and moisture, and avoid overbaking to maintain that perfect, fudgy texture. These brownies are perfect for meal prep, as they stay moist and delicious for days, making them an excellent on-the-go option to support your active lifestyle.

INSTRUCTIONS
Preheat your oven to 350°F (175°C). Grease an 8x8 inch baking pan.
In a large bowl, mix together the mashed bananas, eggs, protein powder, cocoa powder, oat flour, peanut butter, and baking powder.
Stir until the batter is smooth and well combined.
Pour the batter into the prepared pan and spread evenly.
Bake for 22-25 minutes, or until the center is set.
Let the brownies cool before cutting into squares.
TROUBLESHOOTING
My brownies are too dry
Try adding 1-2 tablespoons more liquid (milk, yogurt, or egg whites). Also ensure you're not over-measuring the protein powder - use the scoop and level method.
They didn't rise properly
Check your baking powder is fresh (test by adding to hot water - it should bubble vigorously). Also, don't overmix the batter as this can deflate the air bubbles.
The texture is rubbery
This usually means too much protein powder or overbaking. Reduce baking time by 2-3 minutes and check doneness with a toothpick.
