These fudgy protein brownies are a simple and satisfying way to enjoy a rich chocolate treat while packing in extra protein. Made with just four basic ingredients, they stay moist and dense with a deep chocolate flavor that feels indulgent—yet they’re healthier and easier than traditional brownies. They’re perfect for post-workout snacks, lunchbox treats, or anytime you want a guilt-free dessert.

How to Store
- Store cooled brownies in an airtight container at room temperature for up to 2 days.
- For longer freshness, refrigerate for up to 5 days.
- You can also freeze individual brownies in a sealed bag for up to 2–3 months; thaw before serving.
What Not to Do
- Do not overbake—they should stay fudgy, not dry.
- Do not use underripe bananas; the natural sweetness and moisture come from very ripe fruit.
- Do not skip lining the pan or greasing it well; these can stick without it.
Tips & Variations
- For extra richness, add a handful of dark chocolate chips into the batter.
- Swap almond butter for sunflower seed butter for a nut-free version.
- Add a splash of vanilla extract for enhanced flavor.
- Sprinkle sea salt on top before baking for a sweet-salty contrast.
- Use your favorite chocolate protein powder for flavor variation.
