Ingredients You’ll Need

Nothing weird. Nothing scary. Just good stuff doing good things.
For the Fudge Brownie Base:
- ½ cup unsalted butter – Melted, because we’re not here to cream anything.
- 1 cup granulated sugar – Sweetness is non-negotiable.
- 2 large eggs – Room temp if you remember. If not, whatever.
- 1 tsp vanilla extract – The emotional support ingredient.
- ⅓ cup cocoa powder – Go for unsweetened. We control the sugar here.
- ½ cup all-purpose flour – Just enough structure.
- ¼ tsp salt – Trust me, chocolate needs it.
- 10–12 Oreo cookies, chopped – Roughly. No need to be precise.
For the Cookies ’n Cream Layer:
- ¾ cup white chocolate chips – The creamy magic.
- ¼ cup heavy cream – Makes things smooth and dreamy.
- 8–10 Oreos, crushed – Smash them like they owe you money.
Step-by-Step Instructions

- Preheat your oven to 350°F (175°C).
Line an 8×8-inch pan with parchment paper. Leave some overhang so you can lift the brownies out later like a pro. - Melt the butter.
Do it in the microwave or on the stove. Let it cool slightly so it doesn’t scramble your eggs like a monster. - Mix butter and sugar.
Stir until glossy and smooth. This is where things start looking promising. - Add eggs and vanilla.
Mix well after each egg. You want everything fully combined, not awkwardly streaky. - Add cocoa powder, flour, and salt.
Fold gently. Don’t overmix unless you enjoy dense, sad brownies. - Fold in chopped Oreos.
Try not to snack on too many. Try. - Pour batter into the pan.
Spread evenly and admire your work for a second. You earned that pause. - Bake for 25–30 minutes.
The center should look set but still slightly soft. A toothpick should come out with moist crumbs, not wet batter. - Make the cookies ’n cream topping.
Heat the cream until just steaming, then pour it over the white chocolate chips. Let it sit for a minute, then stir until smooth. - Stir in crushed Oreos.
This is the glow-up moment. - Spread topping over cooled brownies.
Smooth it out, then pop the pan in the fridge for at least 1 hour to set. - Slice, serve, and accept compliments.
Cut into squares and try not to eat half the pan immediately. Or do. I’m not your boss.
Common Mistakes to Avoid
- Skipping the parchment paper.
Enjoy chiseling brownies out of the pan like an archaeologist. Or just line it. - Overbaking the brownies.
Dry brownies are a tragedy. Slightly underbaked is the goal. - Pouring the topping on hot brownies.
It’ll melt, slide off, and emotionally damage you. Let them cool first. - Crushing Oreos into dust.
You want chunks, not Oreo sand. Texture matters. - Using low-quality white chocolate.
FYI, cheap white chocolate can turn grainy and sad. Spend the extra dollar.
Alternatives & Substitutions
- No white chocolate?
Use cream cheese frosting mixed with crushed Oreos. Different vibe, still amazing. - Want them extra chocolatey?
Add ½ cup chocolate chips to the brownie batter. IMO, more chocolate is never wrong. - Gluten-free?
Swap the flour for a 1:1 gluten-free blend. Works like a charm. - No heavy cream?
Full-fat milk works in a pinch, but the topping will be slightly softer. - Feeling chaotic?
Add a drizzle of melted dark chocolate on top. Because why not.
Final Thoughts
These Cookies ’n Cream Oreo Fudge Brownies are unapologetically indulgent, slightly dramatic, and exactly the kind of dessert that makes people ask for the recipe after one bite. They’re perfect for parties, potlucks, or eating alone in your kitchen at midnight. No judgment.
Bake them once, and they’ll become “your thing.” You know, the dessert people request. The one that disappears first. The one you “reluctantly” agree to make again.
Now go preheat that oven and make something ridiculously good. You’ve earned it.
