Ingredients for brownie recipe with chocolate chips and walnuts
Rich cocoa, melted butter, and a touch of espresso—just the start of these decadent brownies.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Melted, cooled slightly |
| Granulated Sugar 🍚 | 1 ½ cups | Lightly packed |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Dutch-processed preferred |
| All-Purpose Flour 🌾 | ¾ cup | Sifted for smooth batter |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| Instant Espresso Powder ☕ | 1 tsp | Enhances chocolate flavor |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Semisweet Chocolate Chips 🍫 | 1 ½ cups | High-quality brand |
| Walnuts 🌰 | 1 cup | Toasted, roughly chopped |
| Baking Powder 🍞 | ½ tsp | Ensures proper rise |
The cocoa powder makes all the difference here. Dutch-processed gives you that smooth, velvety flavor, but regular cocoa works too if that's what you've got. For the butter, unsalted is a must—it lets the chocolate shine. I always grab Land O'Lakes or Plugrá from the grocery store, but any good-quality brand works. The walnuts? Toast them yourself for that nutty aroma—5 minutes in a dry pan until fragrant, then chop roughly. Chocolate chips? Ghirardelli or Nestlé are my go-tos, but don't stress if you've got another brand. Just make sure they're full-sized chips, not mini.
No cocoa powder? Melted dark chocolate works in a pinch—use 6 oz, cooled and stirred into the butter. Short on walnuts? Pecans or almonds are great swaps, but toast them first. No espresso powder? Skip it or use instant coffee granules—just a pinch is enough. The baking powder is non-negotiable though—it keeps the brownies tender. If you're baking at high altitude, add an extra 0.25 tsp. And trust me, the sea salt? It's not just for flavor—it balances everything and makes the chocolate taste even richer.
These brownies stay fresh for 5 days in an airtight container at room temperature, but they're best the day they're baked. If you're making ahead, wrap the pan tightly with foil and store at room temp. For gifting, slice into squares and package in clear cellophane with a ribbon—they make amazing presents. Leftovers? Pop them in the fridge for up to 3 days if you're not in a rush. And if anyone asks, the secret to fudgy perfection is not overbaking—pull them out when the edges are set but the center still jiggles slightly.

Step-by-step instructions for fudgy chocolate chip walnut brownies
Here's how to make rich, fudgy brownies with perfect texture and crunch.
🍳 Step 1: Melt the Butter and Mix Wet Ingredients
In a medium microwave-safe bowl, melt the 1 cup unsalted butter in 30-second intervals, stirring between each, until completely smooth. Let it cool for 5 minutes—it should be warm to the touch but not hot. This prevents scrambling the eggs later.
In a separate large bowl, whisk together the 1.5 cups granulated sugar, 0.75 cup unsweetened cocoa powder, and 1 tsp instant espresso powder until fully combined. The mixture will look like dry sand but will become silky when wet ingredients are added. Add the cooled butter and whisk until smooth.
👨🍳 Step 2: Add Eggs and Aromatics
Crack in the 2 whole large eggs one at a time, whisking vigorously after each addition. The batter will thicken noticeably. Stir in the 1 tbsp vanilla extract and 0.5 tsp sea salt until fully incorporated. Here's the thing—don't overmix. A few lumps are fine; they'll disappear when the dry ingredients are added.
In a small bowl, whisk together the 0.75 cup all-purpose flour and 0.5 tsp baking powder. Sift this mixture into the wet ingredients and fold gently with a spatula until just combined. You're aiming for a thick, glossy batter that coats the back of the spoon—this ensures maximum fudginess.
🥘 Step 3: Fold in Chocolate and Walnuts
Gently fold in the 1.5 cups semisweet chocolate chips and 1 cup toasted walnuts using a rubber spatula. I like to use my fingers for this part—it helps distribute the chocolate evenly. The walnuts should be roughly chopped for better texture. Don't worry if the batter looks uneven; the chocolate will melt beautifully during baking.
This is where the magic happens—those chocolate chips will create pockets of molten goodness in every bite, while the walnuts add that perfect crunch. Spread the batter into a 9-inch square baking pan lined with parchment paper, smoothing the top with a spatula. Tap the pan gently on the counter a few times to remove any air bubbles.
🔥 Step 4: Bake to Perfect Fudgy Perfection
Preheat your oven to 350°F while the batter rests for 5 minutes. This lets the flour fully hydrate and the chocolate settle. Bake the brownies for 25-30 minutes—they're done when a toothpick inserted in the center comes out with moist crumbs (not wet batter) and a few chocolate flecks.
Watch closely after 22 minutes—the edges should be set but the center should still jiggle slightly. Overbaking is the #1 mistake here; it turns fudgy brownies into cakey ones. Let them cool in the pan for 15 minutes before lifting out with the parchment and slicing into 16 perfect squares for serving.
Pro Tips For Making Brownie Recipe With Chocolate Chips And Walnuts
- MELT BUTTER SLOWLY: I learned this the hard way—microwaving butter for brownie batter turns it greasy and uneven. Instead, melt it in a bowl over a pot of barely simmering water (double boiler) until just liquid. This keeps it smooth and prevents graininess when mixed with sugar.
- SIFT THE COCOA: Unsweetened cocoa powder clumps like a stubborn guest. Sift it directly into your dry ingredients before adding wet ingredients—this cuts lumps and ensures even distribution. No sifter? Press it through a fine-mesh strainer with a spoon. (Yes, even if you’re impatient like me.)
- STOP WHEN CENTER’S SLIGHTLY UNDONE: The instant you pull those brownies out, the middle will still look gooey. That’s normal. Overbaking turns them dry and cakey. Aim for a toothpick with moist crumbs—not wet batter, not dry crumbs. Let them rest 5 minutes before slicing, or they’ll crack like overworked dough.
- TOAST THE WALNUTS: Skip this, and your walnuts will taste bland. Toss them in a dry pan over medium heat for 3–4 minutes until fragrant and lightly golden. Watch them like a hawk—they burn faster than you think. Cool completely before folding into the batter, or they’ll release oils and make the brownies greasy. (Your future self will thank you.)
Common mistakes when making great brownie recipe with chocolate chips and walnuts
Overmixing the Batter
I’ve seen this happen more times than I can count—overmixing the batter turns your fudgy brownies into dense, cakey bricks. Once you’ve sifted in the flour and baking powder, fold just until combined. A few small lumps are totally fine—they’ll disappear during baking.
If you whip away like you’re making pancakes, you’ll develop gluten, which makes the texture tough. Trust me, the batter should look thick and glossy, not smooth like cake batter. 🥄
Skipping the Resting Time
Rushing to bake immediately after mixing is a big no-no. Let the batter rest for 5 minutes before going into the oven—this allows the flour to fully hydrate and the chocolate to settle. I’ve tested this recipe countless times, and that resting time makes all the difference in texture.
If you skip it, your brownies might sink in the middle or turn out dry. Patience is key here!
Using the Wrong Pan
Not all baking pans are created equal. A 9-inch square pan is perfect for this recipe, but if you use a round cake pan or a larger pan, your brownies will bake unevenly. The edges will overcook while the center stays underdone.
If you’re in a pinch, a 9x9-inch pan works, but avoid anything smaller—it’ll make your brownies too thick and dense. And for heaven’s sake, don’t use a dark metal pan without checking the baking time—dark pans can cause the edges to burn before the center is done.
Overbaking for "Extra Crispy" Edges
Here’s where most people mess up: they pull the brownies out too late, thinking they’ll get extra crispy edges. But that’s how you end up with dry, cakey brownies instead of the fudgy texture you want. The second the edges are set (around 22 minutes), start checking the center.
A toothpick should come out with moist crumbs and a few chocolate flecks—if it’s completely clean, you’ve overbaked. Pull them out when the center still jiggles slightly. They’ll firm up as they cool. 🔥
Ignoring the Parchment Paper
Greasing the pan is a must, but parchment paper is your secret weapon. It prevents sticking and makes slicing clean squares effortless. If you skip it, you’ll spend more time prying brownies off the pan than enjoying them.
Line your 9-inch pan with parchment, press it gently into the corners, and you’re golden. Pro tip: Draw a light pencil line on the parchment to guide your cuts—it makes serving look like you put in zero effort (but we all know better).
Substituting Ingredients Without Adjustments
Swapping out cocoa powder for melted chocolate or using a different type of flour without adjusting the recipe can throw everything off. If you’re using melted dark chocolate instead of cocoa powder, reduce the sugar by 2 tablespoons—it’s already sweet.
And if you’re at high altitude, add an extra 0.25 tsp baking powder to help with rising. I’ve learned the hard way that these little tweaks make a world of difference. Always read the notes in the ingredients section—those details are there to help you avoid disasters!

Frequently asked questions
Can I make these brownies gluten-free?
Swap the all-purpose flour for a 1:1 gluten-free baking flour blend (like Bob's Red Mill) and add an extra 0.25 tsp xanthan gum if your blend doesn't include it. You may need to reduce the baking time by 1-2 minutes since gluten-free batters can bake faster. For best results, use a kitchen scale to measure ingredients precisely.
How do I store leftover brownies?
For maximum freshness, keep brownies in an airtight container at room temperature for up to 5 days. If you're planning ahead, they freeze beautifully too! Wrap individual squares tightly in plastic wrap, then place in a freezer bag for up to 3 months. Thaw overnight in the fridge for best texture.
What's the best way to toast walnuts?
Toast your walnuts in a dry skillet over medium heat for 5-6 minutes, stirring constantly, until they're fragrant and lightly golden. Let them cool completely before chopping—this prevents them from releasing oils during baking. For extra flavor, add a pinch of cinnamon or cayenne while toasting.
Can I add other mix-ins besides walnuts?
Yes! Try pecans, almonds, or even pretzels for a sweet-salty twist. For extra decadence, fold in white chocolate chips or butterscotch chips along with the semisweet ones. Just reduce the total chocolate by 0.25 cup to maintain the right balance. The key is keeping the mix-ins at 1.5 cups total for proper texture.
Why did my brownies turn out cakey?
Cakey brownies usually happen from overbaking or overmixing. Check your baking time—pull them when a toothpick comes out with moist crumbs (not clean). Also, ensure you're not overmixing the batter after adding flour. For extra fudginess, try adding 2 tbsp sour cream or Greek yogurt to the wet ingredients.
