Ingredients for brownie recipe 9x13 with chocolate chips
These twelve ingredients transform into a 9x13 pan of triple-fudged brownie perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Melted, cooled slightly |
| Granulated Sugar 🍚 | 2 cups | Light brown preferred |
| Cocoa Powder 🍫 | ¾ cup | Dutch-processed for richness |
| All-Purpose Flour 🌾 | ¾ cup | Sifted for even texture |
| Espresso Powder ☕ | 1 tbsp | For deep chocolate flavor |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Semisweet Chocolate Chips 🍫 | 2 cups | Enjoy Life brand for allergies |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Baking Powder 🌾 | ½ tsp | For slight lift |
| Flaky Sea Salt 🧂 | 1 tbsp | For garnish (optional) |
| Walnut Pieces 🌰 | ½ cup | Toasted, chopped (optional) |
The cocoa powder and chocolate chips are non-negotiable here. Dutch-processed cocoa from Ghirardelli or Hershey's gives the deepest flavor, but any quality brand works. For chocolate chips, Enjoy Life is my go-to (allergies aside), but Ghirardelli or Nestlé are solid too. The espresso powder is what elevates this from basic to next-level—Starbucks or La Marzocco are reliable. Pro tip: Toast your walnuts in a dry pan for 3-4 minutes before chopping—they add crunch and richness that makes these brownies sing.
No Dutch-processed cocoa? Natural cocoa powder at 1.5x the amount works, but the flavor will be slightly more acidic. Out of chocolate chips? Chop a 6-oz bar of chocolate (semi-sweet or dark) into chunks. Running short on butter? Coconut oil works in a pinch, but it’ll make the brownies slightly denser. The baking powder is optional—skip it if you prefer ultra-fudgy, but it helps with those coveted cracks. And if you’re feeling fancy, add a pinch of instant coffee granules (1 tsp) for extra depth without the espresso powder.
Store these in an airtight container at room temperature for 3-4 days—they’ll keep best if you wrap the pan tightly with foil first. For longer storage, freeze for up to 3 months. The best part? They actually taste better the next day as the flavors meld. I always make a double batch because these disappear faster than you can say ‘triple-fudged cracks.’ Leftovers reheat beautifully in the microwave for 10-15 seconds, or enjoy them cold for that perfect fudgy bite.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by this recipe because it’s literally a one-bowl job—cream butter and sugar, toss in the dry stuff, fold in chocolate chips, and you’re done. No whisking, no sifting, just stir until the flour’s mostly gone. That espresso powder? It cuts the bitterness of the cocoa while adding this subtle depth that makes it taste like a bakery’s secret.
- Fudgy-Crackly Magic: The secret’s in the butter-to-sugar ratio and that just underbaked center—it’s dense, almost cakey, but with that perfect crispy edge. And when you add those melty chocolate chips? Every bite has that first taste of warm, gooey pockets. Honestly, I’ve made brownies for years, and this is the only one where my husband actually licks the pan.
- Party or Pantry: This pan size is my go-to for everything: potlucks (it’s easy to slice), work lunches (stays fresh for days), or when I’m too tired to bake but still crave something indulgent. Freeze half the batch—thawed, it’s just as good, and no one will guess it sat in the freezer.
- Budget Binge: Five ingredients, all pantry staples, and it feeds a crowd for under $10. That cocoa powder? A 16-ounce bag lasts months, and the espresso powder is a cheap hack for richer flavor. Plus, leftovers? They’re my emergency dessert when I’ve got friends over and forgot to grocery shop. (It’s happened.)
Step-by-step instructions for triple-fudged chocolate chip brownies
Here's how to bake fudgy, crack-topped brownies with melty chocolate chunks every time.
🍳 Step 1: Melt Butter and Mix Wet Ingredients
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal. In a large 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 but not hot to the touch.
In the same bowl, whisk in the 2 cups granulated sugar and 0.75 cup cocoa powder until fully combined and no lumps remain. The mixture will look thick and grainy at first, but keep whisking—this ensures even distribution of chocolate flavor. Here's the thing: don't rush this step. Those few extra seconds of mixing make all the difference in the final texture.
👨🍳 Step 2: Add Eggs, Vanilla, and Dry Ingredients
Crack the 2 whole large eggs directly into the butter mixture (no shells!) and whisk vigorously for 1 minute until the eggs are fully incorporated and the mixture lightens slightly in color. Add the 1 tsp vanilla extract and 1 tbsp espresso powder, whisking until smooth. The espresso powder might seem odd, but trust me—it deepens the chocolate flavor without any coffee taste.
In a separate bowl, sift together the 0.75 cup all-purpose flour, 0.5 tsp salt, and 0.5 tsp baking powder. Gently fold this dry mixture into the wet ingredients using a spatula, mixing just until combined. You'll see some flour streaks, and that's perfect—overmixing develops gluten and makes brownies tough. Add the 2 cups semisweet chocolate chips and 0.5 cup walnut pieces (if using) and fold them in until evenly distributed.
🥘 Step 3: Bake Until Cracked and Set
Pour the brownie batter into the prepared 9x13-inch pan and spread it evenly with a spatula. Tap the pan gently on the counter a few times to remove any air bubbles. Bake for 25-30 minutes—the brownies are done when the edges are set but the center still looks slightly soft. A toothpick inserted in the center should come out with a few moist crumbs, not wet batter.
This is where the magic happens: the top should develop those beautiful, jagged cracks while the interior remains fudgy. If your oven runs hot, start checking at the 22-minute mark. If it runs cool, give it the full 30 minutes. Real talk: the first time you open the oven and see those cracks, you'll know you're doing it right.
🔪 Step 4: Cool and Garnish for Perfect Texture
Remove the brownies from the oven and let them cool in the pan for 15 minutes. Then, carefully lift them out using the parchment overhang and place them on a wire rack. Sprinkle the 1 tbsp flaky sea salt evenly over the top while they're still warm—this enhances the chocolate flavor and adds a delightful contrast.
Let the brownies cool completely before cutting. I know it's tempting to dig in right away, but patience here ensures clean slices and that perfect fudgy texture. Once fully cooled, cut into 12 equal squares (about 2-inch pieces) and serve. Each bite should deliver rich chocolate flavor, melty chocolate chips, and that satisfying crackly top that makes these brownies unforgettable.
Pro Tips For Making Brownie Recipe 9x13 With Chocolate Chips
- MELT BUTTER SLOWLY: I learned this the hard way—dumping cold butter into hot sugar makes a greasy mess that fights you the whole time. Warm the butter in the microwave for 30 seconds, then whisk it into the sugar while it’s still soft but not liquid. The sugar will dissolve faster, and your batter won’t seize up like a stubborn mule.
- SIFT THE DRY STUFF: Flour and cocoa powder clump like a teenager’s laundry if you just scoop and stir. Sift them together with the espresso powder right into the bowl—no extra mess, no lumps, and the espresso disperses evenly. (Yes, even if you’re impatient like me, this takes 30 seconds and makes a real difference.)
- BAKE UNTIL TOOTHPICK TEST FAILS: A clean toothpick means dry, cakey brownies. You want it to come out with moist crumbs clinging to it—like a fudgy hug. Start checking at 28 minutes (for a 9x13 pan) and pull them out when the edges are set but the center still jiggles slightly. They’ll firm up as they cool, I promise.
- CHILL THE BATTER: I was skeptical until I tried it: let the batter sit for at least 20 minutes before baking. The flour absorbs the liquid, the chocolate chips settle, and you avoid the sad, sunken center that happens when you rush it. (Your future self will thank you—trust me.)
Storing and reheating this brownie recipe 9x13 with chocolate chips
Room Temp Storage
Keep your brownies fresh at room temperature by storing them in an airtight container with a parchment-lined lid—this prevents moisture loss and keeps them from drying out. I like using Rubbermaid Brilliance containers because they seal tightly and let me see the brownies through the clear lid.
Place them in a cool, dark spot like your pantry for up to 3-4 days. The first day is always the best, but they’ll still taste amazing after that. 💛
Fridge Preservation
For longer storage, transfer leftovers to the fridge where they’ll stay good for 5-6 days. Wrap the pan tightly with plastic wrap first, then place it in a resealable freezer bag to protect against fridge odors.
When ready to eat, let them sit at room temperature for 10-15 minutes—this makes them easier to cut and enjoy. The cold helps maintain their fudgy texture, but they’ll soften slightly when brought back to room temp.
Freezer Magic
Freezing is the ultimate way to preserve these brownies—up to 3 months without losing quality. Cut them into squares first, then arrange in a single layer on a baking sheet. Freeze solid (about 1 hour), then transfer to a freezer-safe bag or airtight container with parchment between layers.
This prevents freezer burn and makes them easy to grab for late-night cravings. Thaw at room temperature for 1-2 hours or microwave for 10-15 seconds for a quick treat.
Reheating Secrets
Microwave reheating is my go-to for single servings—just pop a square on a plate and heat for 10-15 seconds on 50% power. For even warmth, cover it loosely with a damp paper towel to prevent drying.
If you prefer stovetop, place the brownie in a dry skillet over low heat for 1-2 minutes until warmed through. The key is gentle heat—too much power turns them rubbery. 🔥
Gift-Worthy Packaging
Want to impress? Package individual squares in parchment paper, tie with twine, and add a mini chocolate chip on top for a cute touch. Store these in a gift box or resealable bag with a note—perfect for teachers, coworkers, or anyone who loves chocolate.
These brownies freeze beautifully in this packaging too, making them an easy homemade gift for any occasion. The presentation makes them feel extra special!

Frequently asked questions
Why do your brownies need espresso powder?
The 1 tablespoon espresso powder deepens the chocolate flavor without adding coffee taste—it enhances the natural cocoa richness. Think of it as a flavor amplifier that makes every bite taste more intense and complex. Skip it if you prefer a milder chocolate profile, but I promise you'll notice the difference!
Can I make these brownies without walnuts?
The walnuts are optional and add texture, but you can omit them entirely. For extra richness, try adding 1/2 cup toasted pecans or 1/4 cup chopped dark chocolate chunks instead. If you're avoiding nuts completely, just reduce the chocolate chips to 1 3/4 cups to maintain balance.
How do I fix brownies that came out too cakey?
Too much flour or overmixing causes cakey texture. Next time, measure your 0.75 cup flour precisely (spoon and level) and mix just until combined. For existing brownies, try reheating them briefly in the oven at 300°F for 5-10 minutes—the moisture will redistribute slightly for a denser bite.
What's the best way to cut perfectly clean squares?
Let brownies cool completely first, then chill in the fridge for 15 minutes before cutting. Use a hot knife (dip in hot water and wipe dry between cuts) for clean edges. For 2-inch squares, make your first cut 1 inch from the edge to ensure equal portions. Pro tip: Wipe your knife with a damp paper towel between cuts to prevent sticking.
Can I double this recipe for a larger pan?
Not recommended for a 9x13 pan—the batter would be too thick. Instead, bake two 9x13 pans simultaneously (place on middle and lower racks) or use a 13x18 pan by reducing baking time to 20-25 minutes. For extra insurance, cover the second pan with foil after 15 minutes** to prevent over-browning.
