- Chocolate protein powder: Boosts the protein content, making these brownies a satisfying energy source.
- Cocoa powder: Delivers deep chocolate flavor with minimal calories.
- Vanilla extract: Enhances the sweetness and rounds out the flavors beautifully.
- Baking powder: Gives the brownies just the right lift, making them fluffy but fudgy.
- Pinch of salt: Balances sweetness and intensifies the chocolate and peanut butter notes.

How to Make Protein-Packed Peanut Butter Brownies Recipe
Step 1: Preheat and Prepare Your Baking Dish
Start by heating your oven to 350°F (175°C). While it warms up, line an 8×8-inch baking pan with parchment paper or give it a light grease. This step is essential so your brownies bake evenly and come out easily without sticking.
Step 2: Mix the Dry and Wet Ingredients
In a large bowl, combine the creamy peanut butter, sweet maple syrup or honey, almond flour, chocolate protein powder, cocoa powder, vanilla extract, baking powder, and just a pinch of salt. Mixing all the dry and wet ingredients early helps blend the flavors thoroughly and ensures an even texture throughout.
Step 3: Add the Almond Milk and Chocolate Chips
Pour in your almond milk and gently stir until the batter turns smooth, thick, and glossy. This is the moment to fold in chocolate chips if you want a little extra chocolate joy. The batter should be rich and hold together, but not too dry.
Step 4: Bake to Perfection
Pour the brownie batter into your prepared baking dish and spread it evenly with a spatula. Place it in the oven and bake for about 15 to 18 minutes. To check if it’s done, insert a toothpick into the center; if it comes out clean or with just a few moist crumbs, your brownies are ready.
Step 5: Cool and Slice
Once baked, allow your brownies to cool in the pan for at least 15 minutes to let them set. This step makes slicing easier and helps the flavors meld to perfection. Then, cut into 9 squares and get ready to dig in!
How to Serve Protein-Packed Peanut Butter Brownies Recipe

Garnishes
Add a dollop of Greek yogurt or a drizzle of natural peanut butter on top for extra creaminess and protein punch. A sprinkle of chopped nuts, like walnuts or peanuts, also brings a perfect crunch that complements the soft brownie texture.
Side Dishes
Serve these brownies alongside fresh berries or a scoop of vanilla ice cream for a classic dessert pairing. For a healthier approach, sliced bananas or apple wedges make a refreshing balance to the richness.
Creative Ways to Present
Try stacking brownie squares with layers of whipped coconut cream and peanut butter drizzle for an eye-catching dessert parfait. You could also cut the brownies into bite-sized pieces and skewer them with fruit chunks for a fun party treat that combines sweet and healthy elements.
Make Ahead and Storage
Storing Leftovers
Keep your leftover brownies in an airtight container at room temperature for up to three days. This helps them retain moisture and flavor without drying out. Storing them properly ensures every bite remains as delightful as the first.
Freezing
If you want to enjoy these brownies later, wrap them tightly in plastic wrap and place them in a freezer-safe bag or container. They freeze well for up to three months. When you’re ready, thaw overnight in the fridge or let them come to room temperature for a few hours.
Reheating
To warm them up, pop a brownie square in the microwave for about 15 seconds or until just soft. This will revive their fudgy texture and bring out that fresh-baked warmth, making them taste freshly made again.
FAQs
Can I substitute peanut butter with other nut butters?
Absolutely! Almond butter or cashew butter work wonderfully and provide a slightly different but equally delicious flavor profile. Just make sure to use natural, unsweetened versions for best results.
Is it necessary to use protein powder?
While protein powder is key to making this truly protein-packed, you can omit it if you prefer a classic brownie taste. Just know the texture and nutritional profile will be a bit different without it.
Can I make these brownies vegan?
Yes, by using plant-based protein powder and sweeteners like maple syrup, plus almond or oat milk, these brownies are naturally vegan-friendly and still wonderfully tasty.
How fudgy are these brownies?
They strike a fantastic balance between fudgy and cakey thanks to the almond flour and baking powder combo, so they are moist and rich but still hold their shape for clean slices.
Can I add any mix-ins to the batter?
Definitely! Chopped nuts, dried fruit, or a handful of mini chocolate chips can be folded in to customize your Protein-Packed Peanut Butter Brownies Recipe and add texture variety.
