Desserts
This Hershey Cookies and Cream Brownies recipe delivers the ultimate dessert experience—rich, fudgy layers infused with classic vanilla cookie crunch. The secret lies in swirling crushed Oreos into the batter before baking, creating pockets of sweet, buttery crunch that contrast perfectly with the dense chocolate base.
I developed this recipe after years of testing, ensuring every bite delivers that nostalgic combination of chocolate and vanilla.
The process is straightforward but requires precision: melt chocolate and butter together, then fold in crushed cookies for maximum crunch. A single layer of batter ensures even baking, while the cookie swirls create visual appeal and texture.
Baking at 350°F for 25-30 minutes guarantees a moist center and crisp edges, with no need for extra flour or eggs to bind.
What you’ll end up with is a decadent dessert that looks as impressive as it tastes—deep chocolate layers with golden vanilla cookie swirls throughout. The aroma alone will have everyone gathering in the kitchen, and the first bite delivers that perfect balance of rich chocolate and buttery crunch.
This is the kind of brownie that disappears quickly, so make a batch you can share.
For an extra touch, sprinkle additional cookie crumbs on top before baking or dust with powdered sugar for a bakery-style finish. These brownies are perfect for celebrations, family gatherings, or whenever you need a dessert that feels special. Let’s get baking!
Ingredients for hershey cookies and cream brownies
Twelve ingredients. One unforgettable dessert. The secret’s in the swirl!
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Semi-Sweet Chocolate Bars 🍫 | 12 oz | High-quality chocolate for rich flavor |
| Unsalted Butter 🧈 | 1 cup | Full-fat for best texture |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for smooth batter |
| Granulated Sugar 🍚 | 1 ½ cups | White sugar preferred |
| Packed Brown Sugar 🍚 | ½ cup | Light brown sugar works |
| Large Eggs 🥚 | 2 whole | Room temperature for mixing |
| Vanilla Extract 🍶 | 1 tbsp | Pure extract preferred |
| Oreos Cookies 🍪 | 1 ½ cups | Crushed into fine crumbs |
| Baking Powder 🍞 | ½ tsp | For lift and texture |
| Salt 🧂 | ¼ tsp | Kosher or sea salt |
| Powdered Sugar 🍚 | ½ cup | For dusting finished brownies |
The chocolate is everything—Hershey’s semi-sweet bars are a must for that classic Hershey flavor. I always grab the 12-ounce family-size bars from Target or Walmart because they’re cheaper per ounce and melt beautifully. Butter matters too—full-fat, unsalted gives the richest texture, so don’t skimp. For the Oreos, crush them finely in a food processor or pulse in a bag with a rolling pin. The finer the crumbs, the better they distribute in the batter. And trust me, freshly crushed tastes better than pre-made crumbs from a jar.
No Hershey’s bars? Ghirardelli squares or Nestlé Toll House work in a pinch, but the flavor won’t be quite the same. Short on butter? European-style butter like Plugrá melts smoother, but regular unsalted works too. The sugars can be swapped—turbinado or coconut sugar add depth, but white sugar keeps it classic. For the Oreos, Nabisco Original is the gold standard, but Double Stuf adds extra richness. Pro tip: Toast the crushed cookies for 5 minutes at 350°F to deepen their flavor before mixing into the batter—game-changer!
These brownies keep for 4-5 days at room temperature, wrapped tightly in plastic. For extra freshness, store in the fridge for up to 7 days, but they’ll be even fudgier. Freeze for 3 months by wrapping tightly in foil and plastic—thaw at room temp before serving. The powdered sugar dusting? Do it right before serving so it stays crisp. And if you make extras, portion into squares for easy grabbing—trust me, they disappear fast!
Why You'll Love This Recipe
- Foolproof Mix-Ins: I swear by this recipe because it’s the only one where I don’t have to fuss with measuring cookies—I just chop up a Hershey’s bar and fold it right into the batter. The melted chocolate swirls into the brownies while they bake, so you get that perfect, gooey texture without extra steps.
- Two Flavors, Zero Guilt: Honestly, the combo of rich Hershey’s chocolate and that buttery, slightly crispy brownie base is chef’s kiss. The brown sugar adds just enough caramel depth, so it’s not too sweet—just dangerously addictive. (Yes, even on a Tuesday night.)
- Party-Ready in 45: Between us, this is my secret weapon for gatherings—no one can resist a tray of these. They’re sturdy enough to cut into squares, but still feel special enough for a dessert table. Plus, the Hershey’s chunks make them look like you slaved over them.
- Budget-Friendly Indulgence: I make a double batch every month because it’s cheaper than store-bought treats and lasts forever. The pantry staples (butter, sugar, flour) stretch far, and using a whole chocolate bar means no wasted scraps. Leftovers? They disappear faster than I can say “third helping.”
Step-by-step instructions for Hershey cookies and cream brownies
Here's the method for rich, fudgy brownies with a crunchy Oreo layer—every bite is pure indulgence!
Melt Chocolate and Butter for Ultimate Richness
Break the 12 oz Hershey's Semi-Sweet Chocolate Bars into small pieces and place them in a microwave-safe bowl. Add the 1 cup Unsalted Butter and microwave in 30-second bursts, stirring between each, until completely melted and smooth. You should see a glossy, deep brown mixture that coats the back of a spoon—this ensures maximum chocolate flavor without burning.
I like to melt the chocolate and butter together because the butter helps distribute the chocolate evenly, preventing any graininess. If you prefer a stovetop method, melt them in a double boiler over simmering water, stirring constantly until fully combined. Let the mixture cool slightly for 2-3 minutes before moving to the next step—this prevents scrambling the eggs later.
Mix Wet Ingredients for Perfect Texture
In a separate large bowl, whisk together the 1.5 cups Granulated Sugar and 0.5 cup Packed Brown Sugar until fully combined. Add the 2 whole Large Eggs one at a time, whisking vigorously after each addition until fully incorporated. The mixture should look like a thick, pale yellow custard. Stir in the 1 tbsp Vanilla Extract and mix until just combined—this step builds the foundation for that signature fudgy texture.
Now, slowly pour the melted chocolate-butter mixture into the sugar-egg mixture while whisking continuously. This gradual incorporation prevents lumps and ensures a silky batter. The final mixture should be thick and glossy, like a rich chocolate pudding. If it looks too thin, let it sit for 1-2 minutes—the chocolate will thicken as it cools slightly.
Fold in Dry Ingredients and Crushed Oreos
In a medium bowl, whisk together the 1.5 cups All-Purpose Flour, 0.5 tsp Baking Powder, and 0.25 tsp Salt. Sift the mixture directly into the chocolate batter while gently folding with a spatula. Folding is key here—overmixing develops gluten and makes the brownies tough. Just combine until no flour streaks remain.
Next, crush the 1.5 cups Oreos Cookies into fine crumbs using a food processor or by placing them in a sealed bag and crushing with a rolling pin. Fold half of the crushed Oreos into the batter, reserving the rest for the topping. The batter will look streaked with vanilla crunch—this is exactly what we want!
Layer and Bake for Fudgy Perfection
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal. Pour half of the batter into the pan and spread it evenly with a spatula. Sprinkle half of the reserved crushed Oreos evenly over the batter, pressing down lightly to create a crunchy layer. Repeat with the remaining batter and Oreos, finishing with a final press of the spatula to smooth the top.
Bake for 25-30 minutes, until the edges are set and a toothpick inserted in the center comes out with moist crumbs (not wet batter). The top should look slightly cracked but still fudgy—this indicates perfect doneness. If you prefer a more cake-like texture, bake for 30-35 minutes, but these brownies are at their best when fudgy!
Dust and Slice for Maximum Indulgence
Remove the brownies from the oven and let them cool in the pan for 10 minutes before transferring to a wire rack. Once completely cool, dust the top generously with the 0.5 cup Powdered Sugar using a fine-mesh sieve. This adds a beautiful finish and balances the richness with a touch of sweetness.
Slice into 12 equal squares and serve at room temperature. The contrast of warm, fudgy chocolate with the cool, crunchy Oreo pieces is what makes these brownies unforgettable. Store leftovers in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months for a quick treat!
Pro Tips For Making Hershey Cookies And Cream Brownies
- Melt Chocolate Slowly: I learned this the hard way—dumping chopped Hershey bars into hot butter causes seizing. Instead, melt the butter first (just until it foams), then lower the heat to medium-low and add the chocolate in small batches, stirring constantly. The goal is a smooth, glossy sauce, not a grainy mess.
- Sift That Flour: Skimping on sifting the flour? You’ll end up with dense, cakey brownies instead of fudgy layers. Use a fine-mesh sieve and tap the bowl gently to break up any lumps—this lightens the texture and keeps the cookies-and-cream swirls distinct. (Yes, even if you’re impatient like me.)
- Watch the Swirl: The cookies-and-cream effect relies on timing. Drop dollops of the cookie dough after the chocolate batter is in the pan, then swirl with a knife—just enough to break up the batter but not overmix. If you go too wild, you’ll end up with a marbled disaster instead of clean pockets of flavor.
- Test Doneness Early: These brownies look underdone when they’re actually perfect. After 25 minutes, poke the center with a toothpick—it should have moist crumbs, not wet batter. Pull them out then, tent with foil, and let them sit 10 minutes. Overbaking turns them dry, and nobody wants that.
Pro cooking tips for this recipe
Chocolate Melt Mastery
Melting chocolate and butter together is where the magic begins, but timing is everything. I use 30-second microwave bursts to avoid burning—never melt on high power! Stir between each burst to ensure even melting.
For a smoother finish, strain the melted mixture through a fine-mesh sieve to remove any graininess before mixing with wet ingredients. This step prevents lumps and guarantees a silky texture throughout. 🍫
Batter Consistency Check
The ideal batter should be thick and glossy, like a rich pudding, but not so stiff it resists the spatula. If your batter looks too thin, let it rest for 2-3 minutes—the chocolate will thicken as it cools.
I’ve found that room-temperature eggs incorporate better, so take them out of the fridge 15 minutes before mixing. Over-whisking eggs can add air, which leads to cakey brownies, so whisk just until combined. 🥚
Oreo Crunch Secrets
Crushing Oreos in a food processor gives the most even crumbs, but a rolling pin in a sealed bag works too. For extra flavor, toast the crushed cookies in the oven at 350°F for 5 minutes before folding them into the batter.
This deepens their vanilla notes and adds a subtle toasted crunch. Save ¼ cup of the crushed Oreos for pressing into the top layer—this creates pockets of crunch in every bite. 🍪
Layering Like a Pro
Spread the batter evenly in the pan, then press the reserved Oreos into the top layer with the back of a spoon. This creates distinct crunchy pockets rather than just sprinkling. For a marbled effect, gently swirl the batter with a knife before baking.
I like to bake these in a 9x13-inch pan because it ensures even heat distribution, but a 9-inch square pan works too—just reduce baking time by 2-3 minutes. 🔥
Doneness Test
The toothpick test is key, but don’t rely on it alone. A toothpick with moist crumbs (not wet batter) means they’re done. The edges should pull away slightly from the pan, and the top should have a few cracks.
If the center looks underbaked but the edges are set, tent the pan with foil and bake for 2-3 more minutes. Overbaking dries them out—fudgy is the goal! ⏰
Cooling and Dusting
Let brownies cool in the pan for 10 minutes before transferring—they’ll set faster this way. Dusting with powdered sugar right before serving adds a bakery-style finish. For extra flair, sift the sugar through a fine-mesh sieve while holding it 6 inches above the brownies.
Store leftovers in an airtight container with parchment between layers to keep them moist. 💫

Frequently asked questions
Can I substitute Oreos with another cookie for the crunch?
For a similar texture, try crushed graham crackers, vanilla wafers, or even shortbread cookies. If you want a chocolate twist, use mini chocolate chip cookies or crushed chocolate sandwich cookies. Just adjust the amount to maintain the same ratio—about 1.5 cups of crushed cookies works best for this recipe.
Why did my brownies turn out cakey instead of fudgy?
Cakey brownies usually happen from overmixing or adding too much flour. To fix this, whisk the wet ingredients just until combined, and fold the dry ingredients in gently. Also, make sure you're using the correct amount of flour (1.5 cups)—adding extra can make them dry. For extra fudginess, reduce the baking time by 2-3 minutes and check for doneness early.
How can I make these brownies gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. You may need to add ½ teaspoon xanthan gum to help bind the batter. Also, use gluten-free Oreos or a gluten-free cookie alternative to keep the crunch intact. Test your gluten-free flour blend first to ensure it works with chocolate recipes.
Can I add mix-ins like nuts or chocolate chips?
Yes, but keep it simple! Fold in ½ cup chopped walnuts or pecans for extra texture, or add ½ cup chocolate chips for more chocolate flavor. Just be mindful of the baking time—nuts can burn faster, so check for doneness at 23 minutes. Avoid adding too many mix-ins, as they can make the brownies dense.
How do I store these brownies for maximum freshness?
Store brownies in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually in plastic wrap and freeze for up to 3 months. To reheat, thaw at room temperature for 1-2 hours or warm in the oven at 300°F for 5 minutes to restore the fudgy texture.
