Ingredients
Instructions
1. 1. Prepare your baking pan: Preheat your oven to 350 F (175 C). Lightly grease an 8×8 inch square baking pan and line it with parchment paper, leaving an overhang on two sides. This makes it much easier to lift the brownies out once they’re baked and cooled.
2. 2. Melt the butter and combine with sugar: In a large mixing bowl, pour the melted butter. Add the granulated sugar and whisk them together until well combined and smooth. This creates the base for your fudgy brownies.
3. 3. Add wet ingredients: Crack the eggs into the butter-sugar mixture, one at a time, whisking well after each addition until fully incorporated. Stir in the vanilla extract. The mixture should become light in color and slightly fluffy.
4. 4. Combine dry ingredients: In a separate medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, dark chocolate protein powder, baking powder, and salt. Make sure there are no lumps in the cocoa or protein powder.
5. 5. Mix wet and dry ingredients: Gradually add the dry ingredient mixture to the wet mixture, stirring with a spatula or wooden spoon until just combined. Be careful not to overmix the batter; overmixing can lead to tougher brownies. A few streaks of flour are okay.
6. 6. Fold in chocolate chips: Gently fold in the dark chocolate chips or chunks. Spread the batter evenly into your prepared 8×8 inch baking pan.
7. 7. Bake to perfection: Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs, but not wet batter. The edges should look set, but the center might still be slightly soft, which is perfect for fudgy brownies.
8. 8. Cool before cutting: Let the brownies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. This allows them to set properly and makes for cleaner cuts.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you begin is the first step to a smooth baking experience. This recipe uses common pantry staples, plus a key addition for that protein boost. Opt for good quality dark chocolate for the best flavor, as it truly shines through in these brownies.
INGREDIENTS:

- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1/4 cup dark chocolate protein powder (whey or plant-based)
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup dark chocolate chips or chunks
For simple substitutions, you can use salted butter, just omit the added salt in the recipe. If you don’t have granulated sugar, light brown sugar can work, adding a slightly chewier texture and a hint of caramel flavor. Any good quality unsweetened cocoa powder will do the trick, but Dutch-processed cocoa will give you a darker, less acidic brownie. When choosing your protein powder, select one that you enjoy the taste of, as its flavor will subtly influence the brownies. Both whey and plant-based protein powders work well here. For the chocolate chips, feel free to use milk chocolate or semi-sweet if dark chocolate isn’t your preference, or even a mix of different types of chocolate.

Easy Variations And Serving Ideas That Fit Real Life
These dark chocolate protein brownies are fantastic on their own, but a few simple tweaks and serving suggestions can elevate them even further, making them perfect for any occasion.
For a kid-friendly twist, consider adding a handful of colorful sprinkles to the top of the batter before baking, especially if making them for a Valentine’s Day school treat. You could also swirl in a tablespoon of peanut butter or hazelnut spread for a nutty flavor. If you’re not keen on dark chocolate, simply swap the dark chocolate chips for semi-sweet or milk chocolate chips. For an extra layer of flavor, a pinch of espresso powder added to the dry ingredients will deepen the chocolate taste without making the brownies taste like coffee.
When it comes to serving, these brownies are incredibly versatile. For a simple dessert, cut them into squares and serve them as is. For a more decadent treat, warm them slightly and serve with a scoop of vanilla bean ice cream, a dollop of whipped cream, or a drizzle of raspberry sauce – perfect for a romantic Valentine’s evening. They also make a wonderful addition to a dessert platter for a party or buffet. Pack them in small decorative bags or boxes tied with a ribbon for a thoughtful homemade gift.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have a few common pitfalls. Knowing what to watch out for will ensure your dark chocolate protein brownies turn out perfectly every time.
One frequent mistake is overmixing the batter. When you add the dry ingredients to the wet, mix only until just combined. Overmixing develops the gluten in the flour, leading to tough, cakey brownies instead of the desired fudgy texture. Stop mixing as soon as you no longer see streaks of dry flour.
Another common issue is overbaking. Brownies are notorious for going from perfectly fudgy to dry and crumbly in just a few extra minutes. Start checking your brownies at the 25-minute mark. A toothpick inserted into the center should come out with moist crumbs attached, not wet batter, but also not completely clean. The edges should look set, but the very center might still seem a little soft, which indicates fudginess.
Not lining the pan can also cause frustration. While greasing helps, parchment paper is your best friend for easy removal. Without it, you might struggle to get the brownies out cleanly, especially if they’re still a bit warm and tender. Always leave an overhang for easy lifting.
Finally, not letting the brownies cool completely before cutting can lead to messy, crumbly squares. Warm brownies are delicious but very soft and difficult to cut neatly. Patience is key here; let them cool fully in the pan on a wire rack for at least an hour, or even longer, before slicing.
How To Store It And Make It Ahead Without Ruining Texture
These dark chocolate protein brownies are excellent for making ahead, and they store beautifully, maintaining their fudgy texture for days.
To store them, once the brownies have completely cooled, cut them into individual squares. Place them in an airtight container at room temperature for up to 3-4 days. For optimal freshness and to prevent them from drying out, you can place a piece of parchment paper between layers if stacking them.
If you want to make them further in advance, these brownies freeze exceptionally well. Once cooled and cut, wrap individual brownies tightly in plastic wrap, then place them in a freezer-safe bag or airtight container. They can be frozen for up to 2-3 months. To enjoy, simply thaw them at room temperature for a few hours, or warm them gently in the microwave for 15-20 seconds for a fresh-baked feel.
For make-ahead purposes, you can bake the brownies a day or two before you plan to serve them. Store them uncut in the pan, covered tightly with plastic wrap, at
