This protein-packed brownie bite recipe has completely transformed my approach to healthy treats. After years of struggling to find satisfying desserts that wouldn't derail my fitness goals, these little gems have become my go-to solution for chocolate cravings without the guilt.
I first made these during a particularly challenging diet phase when I was desperate for something chocolatey that wouldn't break my macros. My family was skeptical at first, but now they regularly request these over traditional brownies.
Ingredients
- Ripe bananas: The riper the better for natural sweetness, look for ones with brown spots all over
- Smooth peanut butter or almond butter: Adds healthy fats and creamy texture, choose natural varieties without added sugar
- Vanilla or chocolate protein powder: Provides the protein boost, whey or plant based both work well
- Unsweetened cocoa powder: Delivers rich chocolate flavor without added sugar, dutch processed gives a deeper color
- Optional mini chocolate chips: For that authentic brownie experience, dark chocolate chips minimize added sugar
Step-by-Step Instructions
- Prepare the oven:
- Set your oven to 350°F and gather your ingredients. This moderate temperature allows the brownies to cook through without drying out.
- Mash the bananas:
- In a medium bowl, thoroughly mash your overripe bananas until mostly smooth. Some small lumps are fine and will add texture to your final brownies. The riper your bananas, the sweeter your brownies will be.
- Mix in nut butter:
- Add your peanut or almond butter to the mashed bananas and stir until well combined. This step creates the moist, rich base for your brownies and adds healthy fats.
- Incorporate dry ingredients:
- Gently fold in your protein powder and cocoa powder until completely mixed. The batter will be thick but still moist. Be careful not to overmix which can make the brownies tough.
- Portion and top:
- Divide the mixture evenly between 8 silicone baking cups placed in a muffin tin. Silicone cups prevent sticking without added oils. Sprinkle a few mini chocolate chips on top of each brownie bite for extra indulgence.
- Bake to perfection:
- Bake for approximately 20 minutes. The brownies will appear soft when removed from the oven but will firm up as they cool. This prevents the dry texture common in protein baked goods.

The protein powder is truly the star ingredient in this recipe. I experimented with various brands before finding that whey protein isolate gives the best texture, while plant based proteins add a slightly nuttier flavor profile that complements the chocolate wonderfully. My husband always knows when a batch is in the oven because the house fills with a chocolatey aroma that brings him to the kitchen every single time.
Storage Solutions
These brownie bites actually taste better the next day after the flavors have had time to meld together. Store them in an airtight container in the refrigerator for up to 5 days. The cool temperature helps them maintain their chewy texture and intensifies the chocolate flavor. For longer storage, place them in a freezer safe container with parchment between layers and freeze for up to 3 months. I often make double batches specifically for freezing so I always have a protein rich treat available when cravings strike.
Customization Options
The beauty of this simple recipe is how easily it can be adapted to your preferences or dietary needs. For a nut free version, substitute sunflower seed butter for the peanut or almond butter. To increase the chocolate intensity, add a tablespoon of espresso powder which enhances chocolate flavor without adding coffee taste. For those watching their carbs, swap half the banana for pumpkin puree which lowers the sugar content while maintaining moisture. You can also fold in walnuts, shredded coconut, or a tablespoon of chia seeds for added nutrition and texture variation.
When To Serve
These protein brownie bites are incredibly versatile. They make an excellent post workout snack when your body craves both protein and carbs. Pack them in lunchboxes for a healthier alternative to commercial granola bars. Serve them as a lighter dessert option when entertaining health conscious friends. I even enjoy them crumbled over Greek yogurt for a high protein breakfast that satisfies my sweet tooth first thing in the morning.
