Ingredients for brownie recipe 9x13 with chocolate chips
Fifteen ingredients, one pan, perfect balance of fudgy centers and crispy edges every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for even melting |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smooth texture |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark variety |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Cocoa Powder 🍫 | ¾ cup | Natural, unsweetened preferred |
| Baking Powder 🧂 | ½ tsp | Aluminum-free for best results |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality extract |
| Semisweet Chocolate Chips 🍫 | 2 cups | Nestlé or Ghirardelli preferred |
| Hot Water 💧 | ¼ cup | Just boiled for smooth batter |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor |
| Dark Chocolate Chunks 🍫 | 1 cup | 70% cocoa or higher |
| Flaky Sea Salt 🧂 | ¼ tsp | For finishing top |
The butter-to-sugar ratio is non-negotiable here—cold cubed butter creates those signature cracks while keeping the center moist. Ghirardelli or Valrhona cocoa powder elevates flavor beyond basic brands, and I always grab mine from Williams Sonoma or specialty grocery stores. For chocolate chips, Nestlé or Ghirardelli melt perfectly without seizing, though Trader Joe's has great budget-friendly options. The dark chocolate chunks? 70% or higher cocoa content ensures that rich, intense flavor without overpowering the brownie base.
No vanilla extract? Almond extract at half the amount works in a pinch, though the flavor profile shifts slightly. Short on cocoa powder? Dutch-processed cocoa at the same quantity darkens the brownies but maintains moisture. The baking powder must be fresh—test by mixing with water; if it fizzes, it's good. For a nutty twist, fold in 1/2 cup chopped walnuts with the chocolate chips. The vegetable oil keeps the texture tender, but melted butter at the same quantity adds richness if you prefer.
Store in an airtight container at room temperature for 3-4 days, or refrigerate for 1 week if you prefer firmer texture. For long-term storage, wrap tightly in plastic and freeze for up to 3 months. I always cut into squares before storing—12 perfect portions make gifting or meal prep effortless. Reheat slices at 300°F for 5 minutes to restore that gooey center.

Step-by-step instructions for fudgy chocolate chip brownies
Here's the method for perfect 9x13 brownies with that coveted fudgy interior and crispy edges.
👨🍳 Step 1: Prepare the Wet Ingredients
In a medium saucepan, combine the 1 cup unsalted butter, 2 cups granulated sugar, 0.5 cup packed brown sugar, 0.25 cup vegetable oil, and 0.25 cup hot water. Bring to a gentle boil over medium heat, stirring constantly until the mixture reaches 235°F—this should take about 5-7 minutes. You'll see the sugar dissolve completely and the mixture thicken slightly.
Remove from heat and let cool for 2-3 minutes while you prepare the eggs. In a separate bowl, whisk the 2 whole large eggs until frothy. Slowly pour the hot sugar mixture into the eggs while whisking continuously—this tempering step prevents scrambled eggs. Add 1 teaspoon vanilla extract and mix until fully combined. Here's the thing—this hot sugar mixture will look curdled at first, but it will smooth out as you add the dry ingredients.
👨🍳 Step 2: Combine Dry Ingredients
In a large mixing bowl, sift together the 1.5 cups all-purpose flour, 0.75 cup cocoa powder, 0.5 teaspoon baking powder, and 0.5 teaspoon salt. Create a well in the center and pour in the tempered egg mixture. Gently fold with a spatula just until combined—you should still see some flour streaks. Overmixing develops gluten, which makes brownies tough instead of fudgy.
Fold in the 2 cups semisweet chocolate chips and 1 cup dark chocolate chunks using a rubber spatula. Make sure they're evenly distributed throughout the batter. The chocolate chunks will melt into pockets of molten chocolate while the chips maintain their crunchy texture. Here's where it gets fun—taste a small spoonful of batter. It should be rich, chocolatey, and slightly sweet with no floury aftertaste.
🔥 Step 3: Bake to Perfect Doneness
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 25-30 minutes—this is where precision matters. The brownies are done when a toothpick inserted in the center comes out with moist crumbs but no wet batter.
Don't walk away during the last 5 minutes. Watch for the edges to turn deep golden brown while the center remains slightly underbaked. This creates that perfect contrast of crispy edges and fudgy interior. If your oven runs hot, start checking at the 22-minute mark—every oven behaves differently.
⏰ Step 4: Cool and Finish
Remove from the oven and let cool in the pan for 10 minutes—this prevents cracking as they firm up. Sprinkle the top evenly with 0.25 teaspoon flaky sea salt while still warm. This enhances the chocolate flavor and adds a delightful contrast to each bite.
Lift the brownies out using the parchment overhang and let cool completely on a wire rack for 1 hour before cutting. Real talk—this waiting period is crucial. Cutting too soon results in crumbly brownies instead of that perfect fudgy texture. For the ultimate experience, serve at room temperature with a scoop of vanilla ice cream or a dollop of whipped cream.
Pro Tips For Making Brownie Recipe 9x13 With Chocolate Chips
- MELT BUTTER SLOWLY: I learned this the hard way—dumping cold butter straight into the pan and ending up with greasy, uneven brownies. Warm the butter in the microwave for 30 seconds first, then stir it into the sugar mixture while it’s still liquid. This keeps the texture smooth and prevents lumps that turn into weird, dry pockets in the final brownie.
- WHISK EGGS ROOM TEMP: Cold eggs from the fridge beat like glue and leave your brownies dense. Run them under warm water for 30 seconds or let them sit in a bowl of warm water for 5 minutes—just enough to loosen them up. Your mix will blend better, and the brownies will have that signature fudgy snap instead of a cakey crumble.
- STOP WHEN CENTER IS SOFT: That toothpick test is a lie. Pull it out when the center still has a thin line of wet batter clinging to it—not when it’s completely clean. If you wait for "done," you’ll end up with a dry, cracked slab instead of rich, gooey brownies. Cover with foil 5 minutes early if the edges are browning too fast.
- SWAP 1/4 CUP FLOUR FOR COCOA: This isn’t cheating—it’s upgrading. Replace a quarter of the all-purpose flour with Dutch-process cocoa powder (the kind labeled "natural" or "unsweetened"). It deepens the chocolate flavor and cuts the floury taste without extra effort. Just sift it with the flour first to avoid clumps.
Creative variations of this brownie recipe 9x13 with chocolate chips
Nutty Chocolate Chip Twist
Swap out half the chocolate chips for 1 cup toasted pecans or walnuts—I love pecans for their buttery flavor. Toast them in a dry skillet over medium heat for 3-4 minutes until fragrant, then chop roughly.
Fold them into the batter with the chocolate chips. The nuts add crunch and a sophisticated texture that pairs beautifully with the fudgy base. 🌰
Salted Caramel Swirl
For a decadent twist, make a simple caramel swirl by melting ½ cup caramel sauce (store-bought or homemade) with 1 tbsp butter in a microwave-safe bowl. Once the batter is in the pan, drizzle the caramel mixture in zigzags across the top, then swirl gently with a knife.
Sprinkle with flaky sea salt before baking. The caramel pools create pockets of gooey sweetness that contrast perfectly with the rich chocolate. 🍯
Espresso-Infused Brownie
Boost the chocolate flavor by adding 1 tbsp instant espresso powder to the dry ingredients. This deepens the cocoa notes and adds a subtle coffee undertone that enhances the fudginess.
If you're sensitive to caffeine, use decaf instant espresso—it works just as well. This variation is a game-changer for coffee lovers and adds complexity without overpowering the chocolate. ☕
Peanut Butter Layer
Create a peanut butter brownie by spreading ½ cup creamy peanut butter (like Jif or Skippy) evenly over half the batter in the pan. Top with the remaining batter and bake as directed.
The peanut butter creates a marbled effect with ribbons of nutty goodness throughout. For extra indulgence, drizzle melted peanut butter over the top after baking. 🥜
White Chocolate & Cranberry
Replace 1 cup of the semisweet chocolate chips with 1 cup white chocolate chips and fold in ½ cup dried cranberries (chopped if large). The tartness of the cranberries cuts through the sweetness of the white chocolate, creating a perfect balance.
This variation is especially festive and works beautifully for holiday gatherings. The cranberries add a pop of color too! 🍇
Blondie Version
Turn these brownies into blondies by reducing the cocoa powder to 0.5 cup and adding 1 tsp cinnamon to the dry ingredients. Replace 1 cup of the chocolate chips with 1 cup chopped macadamia nuts for a sweet, nutty twist.
The result is a lighter, cake-like texture with a caramelized flavor that’s perfect for those who prefer something less chocolate-forward. 🌴

Frequently asked questions
Why do your brownies have cracks on top?
The signature cracks happen because of the butter-to-sugar ratio and proper baking technique. The hot sugar mixture creates steam that rises, then cools and contracts as it bakes, forming those beautiful patterns. For extra cracks, ensure your butter is cold when mixing and don't overbake—those golden edges should still be slightly soft in the center.
Can I make these brownies without eggs?
Replace the 2 eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit for 5 minutes to gel). For a richer texture, use 1/2 cup applesauce or 1/2 cup mashed banana. The brownies will be slightly more cake-like but still delicious.
How do I adjust the recipe for a smaller pan?
For an 8x8-inch pan, reduce all ingredients by 50%. For a 9x9-inch pan, use 75% of the recipe. Always bake times are shorter in smaller pans—check at 20 minutes for doneness. Line the pan with parchment paper to prevent sticking, just like the 9x13 version.
What's the secret to extra fudgy brownies?
Use 1/2 cup less flour (1 cup total) and increase the cocoa powder to 1 cup. Also, slightly underbake by 1-2 minutes—the center should look moist but set when you insert a toothpick. The brownies will firm up as they cool. For maximum fudginess, store them in the fridge overnight before slicing.
Can I make these brownies ahead of time?
Yes! Bake them 1 day ahead and store at room temperature in an airtight container for 3-4 days. For longer storage, freeze the whole pan (uncut) for up to 3 months. Thaw overnight in the fridge before serving. Pro tip: Wrap individual portions in plastic wrap before freezing for perfect single servings.
