Start by preheating your oven to 350°F (175°C).
In a mixing bowl, mash the bananas until smooth.
Stir in almond butter, ensuring it blends well with the banana.
Mix in the chocolate protein powder and unsweetened cocoa powder.
Add honey or maple syrup and vanilla extract. Stir the mixture until it’s smooth.
Sprinkle baking powder and a pinch of salt. Mix again.
If you're feeling indulgent, fold in those dark chocolate chips.
Pour the batter into a greased or lined 8x8 inch (20x20 cm) baking dish.
Pop it in the oven and bake for about 20-25 minutes. The top should feel set but slightly soft in the middle.
Once done, let it cool in the pan for about 10 minutes, then transfer to a wire rack.
