Oreo Brownie Delights

There’s a particular hush that settles over the kitchen when chocolate’s on the menu — like Sunday afternoons and grandma’s apron strings. These Oreo Brownie Delights bring that comfort right to your countertop, warm and familiar.

Why make this recipe
Because it’s a little bit of everything sweet from our childhood: a crunchy Oreo base, a tender brownie layer, and a cloud-like chocolate mousse on top. It’s the kind of dessert that gathers folks around the table and keeps bellies — and hearts — full.

How to make Oreo Brownie Delights

Ingredients:

  • 30 Oreo cookies
  • 1/2 cup unsalted butter, melted
  • 1 1/2 cups all-purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon kosher salt
  • 4 large eggs, room temperature
  • 2 cups granulated sugar
  • 3/4 cup unsalted butter, room temperature
  • 2 teaspoons vanilla extract
  • 2 cups whole milk
  • 1 package dry instant chocolate pudding mix (3.9 ounces)
  • 1/2 cup confectioners’ sugar
  • 16 ounces whipped topping, divided
  • 1 jar hot fudge topping (11.75 ounces)

Directions:

  1. Preheat the oven to 350 degrees F. Spray a 9×13-inch baking dish with non-stick spray.
  2. Process, 30 Oreo cookies in a food processor until they are a fine crumb. Set aside 1/4 cup crumbs for topping.
  3. In a large bowl, combine remaining cookie crumbs with melted butter and press into the bottom of the baking dish.
  4. In another bowl, whisk together flour, cocoa, baking powder, and salt.
  5. In a stand mixer, beat eggs, sugar, room temperature butter, and vanilla until light and fluffy, then add the flour mixture on low speed until combined.
  6. Pour brownie batter over the pressed Oreo crust and bake for 25-30 minutes, until just set. Allow to cool to room temperature.
  7. In another bowl, beat milk, pudding mix, and confectioners’ sugar until soft-set.
  8. Fold in 8 ounces of whipped topping and spread over the cooled brownie layer.
  9. Chill in the refrigerator for at least 1.5 hours.
  10. Drizzle hot fudge over the mousse and top with remaining whipped cream and reserved cookie crumbs before serving.

How to serve Oreo Brownie Delights
Cut into generous squares and serve chilled or slightly warmed — either way, a scoop of vanilla ice cream doesn’t hurt. I like to set a big platter in the middle of the table and let folks help themselves, with forks and laughter passing around like another side dish.

How to store Oreo Brownie Delights
Keep leftovers covered in the refrigerator for up to 4 days. If you want to freeze a portion, wrap individual pieces tightly in plastic wrap and place in an airtight container; they’ll keep well for up to 1 month. Thaw in the fridge overnight before serving.

Tips to make Oreo Brownie Delights

  • Press the Oreo crust firmly and evenly so the brownie bakes on a stable base. A measuring cup helps to get that nice compact layer.
  • Let the brownie cool completely before spreading the mousse, or the pudding layer will slide and get too soft.
  • For fluffier mousse, fold the whipped topping in gently with a spatula — we’re keeping air, not beating it out.
  • If you don’t have a stand mixer, a hand mixer will do just fine; just be patient and scrape the bowl down once or twice.

Variations (if any)

  • Peanut butter twist: swirl 1/2 cup warmed peanut butter into the hot fudge before drizzling.
  • Minty delight: use mint Oreos and add a few drops of peppermint extract to the mousse.
  • Boozy touch: stir 1–2 tablespoons of coffee liqueur into the brownie batter for grown-up depth.

FAQs
Q: Can I use low-fat milk or non-dairy milk for the pudding?
A: For best texture, use whole milk as written. If needed, you can substitute a full-fat non-dairy milk (like coconut milk) but texture and flavor will be slightly different.

Q: Do I have to use a stand mixer?
A: No — a hand mixer works well. Beat the eggs and butter until they’re light and fluffy, and mix the flour in low and slow to avoid overworking the batter.

Q: Can I make this ahead?
A: Absolutely. Assemble everything and refrigerate for up to 24 hours before serving; the chilling time helps the layers set and the flavors mingle.

Q: What’s the best way to cut neat squares?
A: Chill well, then run a sharp knife under hot water, wipe dry, and slice — heating the blade between cuts gives clean edges.
