Ingredients for betty crocker hershey brownie mix
Twelve ingredients transform that box mix into restaurant-worthy fudgy brownies—no fancy skills needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Betty Crocker Hershey Brownie Mix 🍫 | 1 box | Classic chocolate brownie flavor |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat for richness |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For extra moisture and depth |
| Granulated Sugar 🍚 | ¼ cup | Enhances fudgy texture |
| Heavy Whipping Cream 🥛 | ½ cup | Full-fat for ultra-fudgy results |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla for authentic flavor |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain for even distribution |
| Semisweet Chocolate Chips 🍫 | 1 cup | High-quality for melty pockets |
| Walnuts 🥜 | ½ cup | Toasted for nutty crunch |
| Baking Powder 🍞 | ½ tsp | Ensures proper rise |
The Betty Crocker box is your base, but the magic happens with the upgrades. Store-brand butter works fine, but Plugrá or Land O'Lakes gives that extra richness—don’t skimp here. Eggs should be at room temperature (pop them in warm water for 5 minutes if they’re cold). For chocolate chips, Ghirardelli or Guittard make a noticeable difference. Walnuts? Trader Joe's sells pre-toasted ones—game changer if you're short on time. Grab Diamond Crystal kosher salt if you can; it dissolves perfectly and doesn’t leave grainy bits.
No vanilla extract? Pure almond extract at half the amount works in a pinch, but vanilla is non-negotiable for that classic brownie taste. Running low on butter? Coconut oil melts like butter but adds a slight coconut note—use if you're okay with that. Want extra fudgy brownies? Swap half the heavy cream for sour cream (it keeps them moist longer). The baking powder is crucial—double-check your box to see if it’s included; if not, add it. And if you’re feeling adventurous, espresso powder (1/2 tsp) deepens the chocolate flavor without altering texture.
These brownies are best made a day ahead—they develop even more depth overnight. Store them in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months (wrap tightly in plastic wrap). For potlucks, portion them into mini loaf pans—they’re perfect for individual servings. The crackly top? That’s your signal they’re done. Let them cool completely before slicing, or the edges will be gummy. Trust me, the wait is worth it.
Why You'll Love This Recipe
- Five-Ingredient Magic: I swear by this combo—just the mix, butter, eggs, a splash of olive oil, and sugar. That’s it. No measuring cups, no stress, no wondering if I forgot something. The olive oil keeps them moist without tasting weird, and honestly? The butter makes them better than the box promises.
- Fudgy Perfection: Here’s what sold me—the Hershey’s mix already has that rich cocoa base, but adding a little extra sugar and olive oil? It turns them into dangerously fudgy, crackly-edged brownies. Not too sweet, not too dry, just that perfect chewy bite. My daughter picks out the biggest pieces first.
- Party in a Box: Between us, this is my secret weapon for gatherings. Double the mix, bake in a sheet pan, and boom—you’ve got a crowd-pleaser that doesn’t require a fancy dessert. Ice cream on top? Even better. (Yes, even on a Tuesday night.)
- Budget Baking Win: I make this all the time because it’s solid—no wasted ingredients, no fancy swaps. The mix is cheap, the butter and eggs are pantry staples, and leftovers? They last in the fridge for days. Plus, I can freeze half the batch for when I’m too tired to bake later.
Step-by-step instructions for Betty Crocker Hershey brownie mix recipe
Here's how to transform boxed mix into decadent, fudgy brownies with restaurant-quality depth.
Melt Butter and Infuse with Olive Oil
In a microwave-safe bowl, melt the 0.5 cup unsalted butter in 30-second intervals, stirring between each, until completely liquid. Remove from microwave and let cool for 2 minutes—this prevents scrambling when mixed with eggs later. While still warm, whisk in the 0.25 cup extra-virgin olive oil and 0.25 cup granulated sugar until fully combined. The olive oil adds incredible moisture and richness that boxed mixes typically lack.
I like to use a hand mixer here for 10 seconds to ensure the sugar dissolves completely. This step creates the foundation for those ultra-fudgy, melt-in-your-mouth brownies we're after. Don't skip the cooling step—hot butter can cook the eggs before they're incorporated.
Combine Wet Ingredients with Eggs and Cream
In a separate large bowl, whisk together the 2 whole large eggs and 0.5 cup heavy whipping cream until smooth. Add the 1 teaspoon vanilla extract and 0.5 teaspoon diamond crystal kosher salt, whisking vigorously for 20 seconds to fully emulsify. This creates a velvety base that will carry all those rich chocolate flavors.
Now carefully pour the melted butter mixture into the egg mixture while whisking continuously. The temperature difference might make it look curdled for a moment, but keep whisking for 30 seconds until everything comes together into a silky batter. This is where the magic happens—the combination of butterfat, cream, and olive oil creates that signature fudgy texture.
Fold in Dry Ingredients and Mix Just Until Combined
Add the 1 box Betty Crocker Hershey Brownie Mix and 0.5 teaspoon baking powder to the wet mixture. Using a silicone spatula, gently fold these dry ingredients in just until no dry spots remain—about 15 strokes. Overmixing develops gluten, which can make your brownies tough instead of tender. The batter should be thick but pourable, with a few chocolate streaks visible.
In a separate bowl, toast the 0.5 cup walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant and lightly golden. Let them cool completely before folding into the batter with the 1 cup semisweet chocolate chips. The toasted walnuts add a wonderful crunch contrast that balances the fudgy texture. Fold these in last so they remain distinct in each bite.
Bake to Perfect Fudgy Perfection
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. Spread the batter evenly into the pan—tap it gently on the counter a few times to eliminate air bubbles. Bake for 25-30 minutes, until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
Here's the secret: I always check for doneness at 22 minutes. The brownies should be just slightly underbaked in the center—they'll continue cooking as they cool. The edges should be set but still slightly soft to the touch. Let them cool completely in the pan for 1 hour before cutting—this prevents them from crumbling at the edges.
Cut and Serve for Maximum Indulgence
Using a sharp, hot knife (dip it in hot water between cuts), slice the brownies into 12 perfect squares. The knife should glide through cleanly—if it sticks, let them cool another 10 minutes. Serve at room temperature for the best texture contrast between the fudgy interior and crisp edges.
These brownies keep well at room temperature for 3 days or can be frozen for up to 3 months. For an extra-special touch, dust with powdered sugar or drizzle with melted chocolate before serving. The combination of rich chocolate, toasted walnuts, and that ultra-fudgy texture makes these worth every extra step—trust me, they're amazing.
Pro Tips For Making Betty Crocker Hershey Brownie Mix
- Melt Butter First: The box says "melted butter," but don’t just toss in cold chunks—heat it in the microwave for 30 seconds, stir, then add another 10 if needed. Cold butter creates lumps that don’t blend smoothly, and you’ll end up with a cakey, uneven texture instead of that rich, fudgy consistency you’re after.
- Use Room-Temp Eggs: Cold eggs from the fridge mix like glue and can make your batter uneven. Crack them into a bowl and let them sit for 10 minutes before adding to the mix—just long enough to soften, not warm through. This ensures a smoother batter and prevents pockets of unmixed egg in your brownies.
- Skip the Olive Oil: Extra-virgin olive oil is a great shortcut, but it adds a grassy flavor that clashes with the chocolate. Stick to the recipe’s melted butter (or a neutral oil like vegetable) for that classic Hershey’s taste. If you’re in a pinch, use a tiny bit—just 1 tablespoon—but don’t go overboard.
- Bake Until Slightly Under: The box says "25–30 minutes," but pull them out when the edges are set and the center still jiggles like Jell-O. Overbaking turns fudgy brownies into dry hockey pucks. Let them cool in the pan for 5 minutes before slicing—this keeps them from crumbling apart when you cut.
Common mistakes when making perfect results
Overmixing the Batter
I’ve seen this happen more times than I can count—especially when people get nervous about whether the batter is fully combined.
The moment you start vigorous mixing after adding the dry ingredients, you’re developing gluten in the flour, which leads to tough, cakey brownies instead of tender, fudgy ones. Stop mixing the instant you see no dry spots—about 15 gentle folds with a silicone spatula is all it takes.
The batter should look thick and streaky, not smooth. 💫
Skipping the Cooling Step
This is where most boxed brownie disasters begin. If you don’t let the melted butter cool for those 2 minutes before mixing with eggs, you’ll end up with scrambled eggs instead of a smooth batter.
The temperature shock causes the proteins in the eggs to cook prematurely, leading to a dense, rubbery texture. I’ve learned this the hard way—trust me, your brownies will thank you.
Using the Wrong Pan Size
A 9x13-inch pan is your best friend here, but I’ve seen people try to make these in 8x8-inch pans or even sheet pans, and the results are always disappointing. The batter needs room to spread evenly and develop that signature crackly top.
If you’re short on space, use a 9x9-inch pan, but bake for 28-32 minutes instead—just keep an eye on them. The edges will burn faster in a smaller pan.
Overbaking for a "Done" Look
Here’s the truth: boxed brownie mixes are designed to be slightly underdone when they come out of the oven. The center should have moist crumbs on the toothpick, not a clean slate. If you bake them until they look fully set, you’ll end up with dry, crumbly brownies.
Let them finish cooking as they cool—this is how you get that perfect fudgy interior. I promise, they’ll set up beautifully.
Ignoring the Parchment Paper
Greasing the pan is a must, but parchment paper takes it to the next level. Without it, brownies can stick even when greased, especially in the corners. The overhang on the sides makes removing them effortless—no need to dig around with a knife.
Pro tip: if you’re using a glass pan, place the parchment directly on the bottom and sides for extra insurance. 🔥
Not Letting Them Cool Properly
This is where people rush and ruin everything. Cutting into brownies too soon leads to crumbly edges and a gummy center. Give them a full 1 hour to cool completely in the pan before slicing.
The texture will firm up perfectly, and you’ll get those clean, professional-looking cuts. Patience really is a virtue here—trust the process!

Frequently asked questions
Can I make these brownies without walnuts?
The walnuts add texture but aren't essential. Simply omit them if you prefer a smoother texture or have nut allergies. For extra richness, add an extra 0.25 cup of chocolate chips instead. The fudgy texture will still be perfect—just without the crunch!
Why do your brownies look different from the box instructions?
Our recipe uses upgraded ingredients like olive oil and heavy cream that create a richer, fudgier texture than the basic box instructions. The crackly top comes from baking in a hot oven until just set—this is what gives them that restaurant-quality look. Don't worry, they're still just as delicious!
Can I substitute sour cream for the heavy cream?
Yes! Swap the 0.5 cup heavy cream for 0.5 cup sour cream for even more moisture and a slightly tangy flavor. Just be sure to fold it in gently to avoid overmixing. These brownies will stay fudgy longer when stored, making them perfect for meal prep.
How do I prevent my brownies from cracking on top?
Cracking is normal and actually desirable—it means they're perfectly baked! For fewer cracks, try baking at 325°F instead of 350°F for 30-35 minutes. The slower bake creates a smoother surface while still keeping them fudgy inside. Just don't overbake—they should be slightly underdone when removed.
Can I make these brownies in a smaller pan?
For best results, stick to a 9x13-inch pan—this gives the perfect thickness. If you must use a smaller pan (like 8x8-inch), reduce baking time to 22-26 minutes and watch closely. The edges will cook faster in a smaller pan, risking burning while the center stays underdone.
