Instructions

Step 1

Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, leaving an overhang on two opposite sides. This overhang will act as handles to easily lift the brownies out after baking. If you don’t have parchment, generously grease the pan with butter or nonstick spray, but parchment ensures clean edges and effortless removal. While the oven heats, take your eggs out of the fridge to bring them to room temperature—cold eggs can seize the melted butter and create a denser texture. If you’re short on time, place the eggs in a bowl of warm water for 5 minutes.

Step 2

In a medium mixing bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, and salt. Sifting the cocoa powder is optional but recommended—it breaks up any lumps and ensures a smooth, fudgy brownie. The flour provides structure, while cocoa brings deep chocolate flavor without added fat. Set the dry ingredients aside. If you’re adding protein powder, whisk it in now; note that protein powder can absorb more liquid, so the batter may be slightly thicker—that’s fine.

Step 3

In a large bowl, combine the melted butter (cooled to room temperature so it doesn’t cook the eggs), granulated sugar, and brown sugar. Whisk vigorously for about 1 minute until the mixture is smooth and glossy. The brown sugar adds moisture and a subtle caramel note. Add the eggs one at a time, whisking well after each addition, then stir in the vanilla extract. The batter should be thick, shiny, and fall in ribbons when you lift the whisk. This emulsion of fat and sugar is the secret to a chewy, crackly top.

Step 4

Pour the wet ingredients into the dry ingredients and fold gently with a rubber spatula until just combined—about 15 strokes. Overmixing develops gluten and will make the brownies tough and cakey rather than fudgy. You want a few streaks of flour remaining; they’ll disappear as you fold in the chocolate chips. Fold in the dark chocolate chips until evenly distributed. The batter will be thick and slightly sticky.

Step 5

Spread half of the brownie batter into the prepared pan, using a spatula to smooth it into an even layer. Arrange half of the strawberry slices in a single layer over the batter, pressing them gently into the surface. Strawberries add pockets of fruity jamminess and a burst of acidity that cuts through the rich chocolate. Spoon the remaining batter over the strawberries and carefully spread it to cover—don’t worry if a few strawberries peek through; that adds rustic charm. Top with the remaining strawberry slices, gently pressing them into the batter.

Step 6

Bake in the preheated oven for 20–25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). The brownies will continue to set as they cool, so underbaking slightly ensures a fudgy texture. For a gooey center, aim for 20 minutes; for firmer, cake-like brownies, go to 25. The edges should be set and pulling away from the pan slightly. Remove from the oven and place the pan on a wire rack to cool completely—at least 1 hour. Cooling is essential; cutting warm brownies results in a crumbly mess. Once cool, use the parchment overhang to lift the entire block onto a cutting board and slice into 16 squares. For clean cuts, use a sharp chef’s knife and wipe it clean between slices.

For best results

  • For the best flavor and texture, use high-quality cocoa powder like Dutch-processed. Dutch-processed cocoa is treated with an alkali to neutralize acidity, resulting in a smoother, richer chocolate taste and a darker color. Natural cocoa works too, but expect a slightly more acidic flavor and lighter hue. If using natural cocoa, ensure your baking powder is fresh—it reacts with the cocoa's acidity to leaven properly.
  • Fresh strawberries are ideal, but if strawberries are out of season, you can use frozen strawberries. Thaw them first and pat them dry with paper towels to remove excess moisture; otherwise, the brownies can become soggy. Alternatively, freeze-dried strawberries (crushed) add intense flavor without extra liquid—sprinkle them over the batter for a vibrant berry punch.
  • To boost the protein content without sacrificing texture, add a scoop of unflavored or chocolate whey protein powder. Whey blends more smoothly than plant-based proteins and doesn't dry out the brownies as much. If using plant-based protein, add an extra tablespoon of butter or applesauce to compensate for its absorbency. Remember that protein powder can make the batter thicker, so don't overmix.
  • Achieving that crackly, shiny top crust is a hallmark of perfect brownies. The key is dissolving the sugar thoroughly in the melted butter and eggs. Whisk the sugar-butter mixture until it's smooth and no longer gritty. Also, using room-temperature eggs helps the emulsion stay stable. If you want an extra crackly top, beat the eggs and sugar together for 2–3 minutes until pale and thick before adding the butter.
  • Store leftover brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. To freeze, wrap individual brownies tightly in plastic wrap, then place in a freezer bag. They'll keep for up to 3 months. Thaw at room temperature or microwave for 15 seconds for a warm, gooey treat. Pro tip: warm a brownie in the microwave for 10 seconds and top with a scoop of vanilla ice cream for an indulgent dessert.
  • If you prefer a more intense chocolate flavor, replace the dark chocolate chips with semi-sweet or bittersweet chocolate (60–70% cocoa). You can also add a tablespoon of instant espresso powder to the dry ingredients—coffee doesn't make the brownies taste like coffee; it enhances the chocolate depth, making it taste even richer.

Variations

  • Vegan & Dairy-Free: Substitute the butter with vegan butter or coconut oil (use refined for neutral flavor). Replace eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg, let sit for 5 minutes). Use dairy-free chocolate chips. The texture will be slightly denser but still delicious. For a protein boost, use a vegan protein powder like pea or brown rice.
  • Gluten-Free: Swap the all-purpose flour with a 1:1 gluten-free baking blend that contains xanthan gum (like Bob's Red Mill). Do not use almond flour or coconut flour alone, as they will change the texture drastically. The brownies will be slightly more tender but equally fudgy. Check that your cocoa powder and chocolate chips are certified gluten-free if necessary.
  • Peanut Butter Swirl: After spreading the batter in the pan, drop spoonfuls of peanut butter (about 1/4 cup) over the top and swirl with a knife. The peanut butter adds protein and a salty-sweet contrast. For a nut-free version, use sunflower seed butter.
  • Raspberry Chocolate: Replace strawberries with fresh raspberries. Raspberries are more tart and break down into jammy pockets. They pair beautifully with dark chocolate. You can also add a handful of white chocolate chips for a raspberry white chocolate brownie.
  • Mint Chocolate: Add 1/2 teaspoon peppermint extract to the wet ingredients and fold in 1/2 cup of chopped Andes mints or mint chocolate chips. Top with crushed candy canes for a festive holiday twist. The mint refreshes the palate and complements the strawberries.

Common Questions

Can I use frozen strawberries instead of fresh?
Yes, you can use frozen strawberries, but it’s important to thaw them first and pat them very dry with paper towels to remove excess moisture. Frozen berries release water as they thaw, which can make the brownies soggy if not drained. Also, frozen strawberries are softer, so handle them gently when placing on the batter. For best results, use fresh strawberries when available.
Why did my brownies turn out cakey instead of fudgy?
Cakey brownies are usually caused by overmixing the batter after adding the flour, which develops gluten. To keep brownies fudgy, mix until just combined—a few streaks of flour are fine. Also, check your oven temperature; an oven that’s too hot can cause the brownies to rise too quickly and become cakey. Finally, using too much flour (by scooping instead of spooning and leveling) can dry them out. Always spoon flour into your measuring cup and level with a knife.
How can I make these brownies higher in protein?
The easiest way is to add a scoop (about 30g) of chocolate or vanilla protein powder to the dry ingredients. Reduce the flour by 2 tablespoons to compensate for the added powder. Whey protein works best for texture. You can also replace the butter with Greek yogurt (use half the amount) or add an extra egg white for more protein without affecting flavor much. The brownies will be slightly denser but still delicious.
Can I make these brownies without eggs?
Yes, you can substitute eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg, let sit for 5 minutes until gelled). The brownies will be a bit denser and less rich, but they’ll still hold together. Alternatively, use a commercial egg replacer or 1/4 cup unsweetened applesauce per egg. Note that applesauce adds moisture, so you may need to bake 2–3 minutes longer.
How do I store these brownies and how long do they last?
Store brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. To freeze, wrap each brownie individually in plastic wrap, then place in a freezer-safe bag or container. They’ll keep for up to 3 months. Thaw at room temperature or microwave for 15–20 seconds for a warm, gooey treat. Avoid storing in the refrigerator without an airtight container, as they can dry out.
Can I use a different type of chocolate?
Absolutely! You can substitute dark chocolate chips with milk chocolate, semi-sweet, or white chocolate chips. For a richer flavor, use chopped chocolate bars instead of chips—they melt into pools of chocolate throughout the brownie. If using white chocolate, reduce the sugar slightly (by 2 tablespoons) to balance sweetness. Bittersweet chocolate (60–70% cocoa) is our favorite for a deep, sophisticated flavor.
My brownies stuck to the pan even though I greased it. What went wrong?
Even with greasing, brownies can stick if the pan isn’t lined properly. We highly recommend using parchment paper with overhanging edges—it’s the foolproof method. If you don’t have parchment, grease the pan thoroughly with butter or nonstick spray, then dust with cocoa powder (not flour) to prevent white marks. Allow the brownies to cool completely before cutting; warm brownies are more fragile and tend to stick.
