Hershey Cookies and Cream Brownies Recipe: Fudgy Layers With Crunchy Cookie Bites

This Hershey cookies and cream brownies recipe delivers the ultimate dessert experience—rich, fudgy layers infused with the iconic flavor of Hershey’s chocolate and crunchy cookie bits. The secret lies in blending melted chocolate with cookie pieces for an even distribution that keeps every bite packed with that nostalgic taste.

I've perfected this technique over years of baking, ensuring the perfect balance between dense brownie texture and cookie crunch.

The recipe combines classic brownie ingredients with a twist: high-quality cocoa powder, melted butter, and a touch of vanilla to enhance the chocolate flavor. What sets these apart is the addition of crushed cookies and Hershey’s chocolate chunks, which bake into the brownies for a marbled effect.

Baking at 350°F for 25–30 minutes ensures a perfect texture—fudgy yet firm enough to slice cleanly. The aroma filling your kitchen will have everyone anticipating that first bite, where the combination of warm chocolate and cool cookie crunch creates a harmonious flavor.

This recipe is ideal for special occasions or when you simply crave a decadent treat that feels like a hug in dessert form.

Serve warm with a dollop of whipped cream or a drizzle of melted chocolate for an extra indulgent touch. The versatility of this recipe means it works as a crowd-pleasing dessert or a personal indulgence. Let’s get baking!

Ingredients for hershey cookies and cream brownies

Twelve ingredients for a showstopping dessert that packs Hershey’s chocolate and cookie crunch in every bite.

The chocolate matters most here. Hershey's Milk Chocolate Bars are non-negotiable—nothing else gives that nostalgic crunch. Grab the classic milk chocolate, not those weird white or dark variants. Oreos? Stick to the original—frosted or double-stuffed change the texture. For the cocoa powder, Hershey's Special Dark or Dutch-processed from the baking aisle works perfectly. The butter should be unsalted—salted will throw off the balance. Pro tip: melt the chocolate and butter together over hot water (double boiler) for ultra-smooth blending.

No Hershey's bars? Melted milk chocolate chips (like Hershey's brand) in a pinch, but the texture won't be identical. Out of Oreos? Crushed graham crackers or vanilla wafers add crunch, though they won't taste the same. The baking powder is critical—don't skip it! For a richer flavor, swap half the granulated sugar for turbinado sugar. Want extra fudgy brownies? Add 1/4 cup more cocoa powder. The hot water trick for the chocolate mixture is a game-changer—it keeps everything smooth without scrambling the eggs.

These brownies are best served the day they're made, but they keep 3 days at room temperature in an airtight container. For longer storage, wrap tightly and refrigerate for up to 1 week. Freeze for 3 months by wrapping each slice individually. The secret to perfect slices? Let them cool completely before cutting—trust me, it's worth the wait. Double the recipe? Use two 9x13-inch pans for even baking.

Step-by-step instructions for fudgy cookies and cream brownies

Transform simple ingredients into decadent brownies with rich chocolate layers and crunchy Oreo surprises.

Chop the 12 oz Hershey's Milk Chocolate Bars into ½-inch chunks and place them in a microwave-safe bowl. Microwave in 30-second bursts, stirring between each, until completely melted and smooth. Stir in the 0.5 cup hot water until fully incorporated—this creates a silky chocolate base.

While the chocolate melts, crush the 1.5 cups Oreo Cookies into fine crumbs using a food processor or rolling pin. You want a texture between powder and small pieces—this ensures maximum crunch without overpowering the fudgy layers. Set the crumbs aside for layering later.

In a large mixing bowl, combine the 1 cup unsalted butter (cooled slightly), 2 cups granulated sugar, and 0.5 cup packed brown sugar. Whisk until fully melted and smooth. Add the 2 whole large eggs one at a time, mixing well after each addition. Stir in the 2 tsp vanilla extract and 0.25 cup vegetable oil until the mixture is uniform and slightly thickened.

In a separate bowl, sift together the 1.5 cups all-purpose flour, 0.75 cup unsweetened cocoa powder, 0.5 tsp baking powder, and 0.25 tsp salt. Gradually fold the dry ingredients into the wet mixture until just combined—avoid overmixing to keep the brownies tender. The batter should be thick but pourable.

Pour half of the brownie batter into a 9x13-inch baking dish, spreading it evenly with a spatula. Dollop spoonfuls of the melted chocolate mixture over the batter, then sprinkle half of the Oreo crumbs evenly across the surface. Use the back of the spatula to press the crumbs lightly into the batter—this ensures they stay in place during baking.

Repeat with the remaining brownie batter, chocolate mixture, and Oreo crumbs. The final layer should be brownie batter to create a clean top. Swirl the back of a spoon through the batter to create marbled chocolate streaks—this adds visual appeal and extra chocolate flavor.

Preheat your oven to 350°F and bake the brownies for 25-30 minutes, or until a toothpick inserted in the center comes out with moist crumbs (not wet batter). The edges should be set but the center should still feel slightly soft—this ensures a fudgy texture. If the top browns too quickly, tent the pan with foil after 20 minutes to prevent over-browning.

Let the brownies cool in the pan for 15 minutes before slicing. This resting time allows the layers to set and the flavors to meld. For best results, refrigerate for 1 hour before serving—this enhances the chocolate flavor and makes the Oreo crunch even more pronounced. Cut into 12 equal squares and enjoy the perfect balance of rich, fudgy brownie and crunchy cookie bites.

Dietary considerations for hershey cookies and cream brownies

Gluten-Free Swap

Replace the 1.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend like Bob’s Red Mill or King Arthur. Add ½ tsp xanthan gum to mimic gluten’s binding properties. Use the same measuring cups, but sift the blend thoroughly to avoid lumps.

The texture will be slightly denser but still fudgy—just bake for 2-3 minutes longer at 350°F to ensure doneness. 🌾

Dairy-Free Adaptation

Swap the 1 cup unsalted butter for 1 cup dairy-free butter (like Earth Balance or Miyoko’s) and use vegan milk chocolate bars (like Enjoy Life brand). Replace the 2 whole eggs with 2 flax eggs (2 tbsp ground flaxseed + 6 tbsp water, mixed and rested for 5 minutes).

The brownies will still hold together beautifully, though the texture may be slightly less rich. For extra moisture, add 1 tbsp applesauce to the batter.

Reduce the 2 cups granulated sugar to 1.5 cups and replace the remaining 0.5 cup with monk fruit sweetener (like Lakanto) or erythritol. Use a 1:1 ratio for substitution, but taste as you go—the sweetness varies by brand.

The brownies will still be decadent but with fewer calories. Pair with extra chocolate chunks to compensate for the reduced sweetness. 🍫

Nut-Free Version

Skip the vegetable oil and replace it with avocado oil (neutral flavor) or melted coconut oil (adds subtle coconut notes). Ensure all other ingredients—like chocolate bars and cookies—are nut-free.

For extra richness, fold in ½ cup dairy-free chocolate chips (like Enjoy Life) into the batter before baking. Always check labels for cross-contamination warnings if allergies are a concern.

Combine the dairy-free and gluten-free adaptations for a fully vegan treat: use gluten-free 1:1 flour blend, dairy-free butter, flax eggs, and vegan chocolate bars. Add 1 tbsp vanilla extract to enhance flavor, as vegan versions can sometimes lack depth.

Bake in a parchment-lined pan for easy removal—these brownies are so rich, they’ll practically melt in your mouth. 💚

For egg-free brownies, use aquafaba (3 tbsp chickpea brine whipped to stiff peaks) as a substitute for eggs. For nut-free kitchens, avoid cross-contamination by using separate utensils and cleaning surfaces thoroughly.

If making for soy allergies, opt for sunflower seed butter** instead of peanut butter in any variations. Always double-check ingredient labels—even "safe" brands can change formulations. 🛡️
