Oatmeal Chocolate Chip Cookie Dough Peanut Butter Brownies {aka Dad’s favorite dessert}

Oatmeal Chocolate Chip Cookie Dough Peanut Butter Brownies 2With Father’s Day right around the corner, I thought it only fitting that I make the most ridiculous dessert combining all of my husband’s favorite things.

1. Chocolate.

2. Oatmeal Chocolate Chip Cookie Dough.

3. Peanut Butter.

4. Peanut M&M’s.

I contemplated throwing some Reese’s peanut butter cups into the mix too, but forgot to pick them up at the store. I seriously thought about making another trip just for those, but didn’t want to change out of my fat pants. —>ironic.

Anyways, I LOVED these. Love love loved them. And so did my husband. Sugar high to the max, baby.

I like sugar highs, incase you were in question.

Gord thoroughly enjoyed this gift as well. I do it because he’s a good Dad.
Gord & BrookeSee? Good Dad….with a nice set of pipes.


So, tell your Dad you love him with something sweet!

Hi Dad! Love you! Glad you like my pulled pork recipe 🙂

Here’s how you make these treats:
brownies 1Start with a boxed brownie mix. I used Pillsbury 19.6 oz box…or something close to that. Stir in some melted butter and two eggs. Stir until smooth.

brownies 2Spread into a greased and lined 9×9 baking dish and bake 25-25 minutes. Set aside to cool.

Cookie Dough 1For the oatmeal chocolate chip cookie dough, mix together some butter, sugar, powdered sugar, brown sugar, vanilla, milk, flour and salt all together.

    • Do you have to wait for the brownies to cool completely before assembling?

      • I would wait at least 30 minutes so they’re not piping hot…a little warm is fine!


  17. These were SO GOOD. So sweet. I could only handle about one piece and I left the drizzle off. I had to add a bit more milk to the peanut butter mixture to make it spread-able but I wonder if that’s just cause I’m at a 6000 foot elevation? Anyway. Thanks so much for sharing these, so good. Looking forward to tex mex chicken pasta on the menu tonight.

  18. Shouldn’t this be called “Diabeetus”? Looks awesome!

  19. This seriously looks delish and i want to try it but I noticed u actuallynuse flour for the cookie dough layer, but there is no need to bake??
