Ingredients You’ll Need

This recipe uses simple ingredients with one fun addition that makes all the difference.

Main Ingredients

  • 1 box brownie mix (standard size)
  • 2 large eggs
  • 1/3 cup vegetable oil
  • 1/2 cup all-purpose flour

Add-Ins

  • 8–10 Oreo cookies, roughly chopped
  • 1/2 cup chocolate chips (optional)
  • 1 teaspoon vanilla extract (optional)

Choosing and Preparing the Oreos

The way you prepare the Oreo cookies affects the final texture.

Rough Chopping

Break the cookies into medium-sized chunks. This ensures you get both crunch and creamy filling in each bite.

Don’t Crush Too Fine

Too many small crumbs can disappear into the dough instead of creating texture.

Keep Some Larger Pieces

Larger chunks create more noticeable bites of cookies and cream.


Step-by-Step Instructions

Follow these steps to create cookies that are rich, soft, and packed with Oreo flavor.

Prepare the Oven

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

Mix the Dough

In a large bowl:

  • Combine the brownie mix, eggs, and vegetable oil.
  • Stir until smooth.

Add the flour and mix until a thick dough forms.


Adding the Oreo Chunks

Fold Gently

Add the chopped Oreo pieces and chocolate chips to the dough.

Even Distribution

Mix gently to ensure the chunks are spread throughout without breaking them too much.


Shaping the Cookies

Scoop the Dough

Use a spoon or cookie scoop to portion out the dough.

Roll into Balls

Gently shape into balls for a uniform look.

Add Extra Oreo Pieces on Top

Press a few pieces onto the top of each cookie for a decorative finish.

Space Evenly

Place cookies about 2 inches apart on the baking sheet.


Baking Instructions

Bake Time

Bake for 9–11 minutes.

Visual Cues

The filling inside the Oreo pieces adds a subtle creaminess.


Tips for Perfect Results

Don’t Overmix
