Sugar-free Protein Banana Brownie!
This Sugar-free Protein Banana Brownie is a rich, moist, yet low-calorie treat that satisfies sweet cravings without the sugar. It’s naturally sweetened with ripe bananas and honey or maple syrup. This brownie is perfect for a high-protein, low-sugar breakfast, post-workout snack, or healthy dessert!

NOTES
- Whey can make baking a bit drier—if your batter looks extremely thick, add a splash of milk (1–2 tbsp) to loosen it.
INGREDIENTS
- 280 g ripe bananas (about 3 medium-large), mashed
- 2 eggs
- 60g chocolate whey protein* I used Biotech Hazelnut
- 20g cocoa powder
- 100g oat flour
- 30g honey or maple syrup
- 30g peanut butter (1 heaping tbsp)
- 60ml milk
- Pinch of salt
- 1/2 tsp baking powder
- 1/2 tsp baking soda
- Handful of chocolate chips or nuts (optional)
INSTRUCTIONS
- Preheat the oven to 180°C (350°F). Line a small loaf tin with baking paper or lightly grease it.
- Mash the bananas in a large bowl until smooth.
- Add the eggs to the bananas and mix until combined.
- Add the oat flour, whey protein, salt, baking powder, and baking soda. Mix just until combined — do not overmix.
- Fold in the chocolate chips or other mix-ins.
- Pour the batter into the prepared loaf tin.
- Bake for 30-35 minutes, depending on your oven and tin size. The bread is done when a toothpick inserted into the center comes out with wet crumbs. It should be moist!
- Remove from the oven and let cool in the tin for 10–12 minutes, or enjoy HOT!
