Cookies and Cream Swirled Brownies with Chocolate Peanut Butter Ganache

I love brownies and have been wanting to make this idea I’ve had for the last few weeks now. I finally decided this morning to do it. I had all intentions of making homemade brownies, but ran out of time and grabbed my handy box mix. You can use this same concept with your favorite homemade brownie mix. Cookies and cream is one of my favorite combos and talk about yummy swirled in these brownies, I knew it would be fantastic !

As if that wasn’t good enough, I’ve frosted them with a decadent chocolate peanut butter ganache that will have you licking the bowl! I gotta run, my little guy is having a hay day with the goldfish all over my carpet! Enjoy everyone!!

  • 1 box brownie mix 9x13 size
  • 8 oz softened cream cheese
  • 1/3 cup sugar
  • 10 Oreos broken into pieces
  • 1 cup semi sweet chocolate chips
  • 1 ½ tablespoons creamy peanut butter
  • 3 tablespoons half and half


  • Preheat oven to 350 degrees F. Prepare brownie mix according to package directions and place into a 9x7 inch baking dish that has been lined with tin foil and sprayed with cooking spray.
  • In a medium bowl, stir together the cream cheese and sugar until smooth. Stir in Oreo Cookie pieces until combined. Using a spoon, spoon cookies and cream mixture evenly over brownie mix. Using a knife, gently swirl cookies and cream into brownies without scraping the bottom of the dish. Bake for 40-45 minutes or until toothpick comes out clean from center. Cool completely.
  • Place chocolate chips into a microwave safe bowl and microwave for about 1 minute. Stir in peanut butter and stir chocolate chips until smooth. Place back in the microwave for 15-30 more seconds if not smooth. Stir in half and half until glossy smooth, then spread over cooled brownies. Cut into squares and serve.


**I like a thicker brownie, so I use the smaller baking dish, but you can use the 9x13 inch size as well.**

    Yum! I made these last night and they were amazing. As my husband was eating them he actually said, “I want to eat these until I get so fat I explode.” Take that as a great compliment.

  4. Rachelle

    YUMMM! I think I’ll have to make those in 6 months from now, haha I have baked so much lately, I’d probably be in trouble. Those look really good.

    Hey girl!
    Well, I am going to make the brownies today. I will give you an update later. Wish me luck….Love Mona

    These look fantastic. Thought I’d let you know that at Smart n Final they have a huge carton of oreo crumbs for about $12. I vacuum seal them and store them and they are great…just like the crumbled cookies but much cheaper and I am not as tempted to just eat them plain!

  7. Gary and Angela

    I made these Sunday night for my husband and holy cow–they are awesome! Such a good recipe! Thanks!

  8. Prudy

    What a yummy treat! How do you decide which recipes to share and which to save for contests? Your last two brownies have seemed very contest worthy!

  9. Chelsea_Travis_Baby

    Do you find that the crunchy peanut butter is just as good as smooth if you want a “nutty” bite? I love peanut butter, but only have crunchy.

  10. Emiline

    Oh, gosh. I wish I had an oven so I could bake these. Maybe I could do it in a microwave…Nahh.

    Hey Jenny… I just stubbled onto your blog and can I just say that your brownies had me at hello!!They look SO yummy. I might even need to make a grocery run and pick up some Oreos! Thanks for sharing great recipes for all of us bakers.

  12. Veronica

    Oooo cookies and cream in a brownie-that sounds so good! I’ll bet eating them warm with a scoop of ice cream and a little hot fudge sauce would be divine!

  13. Kim A

  14. RecipeGirl
