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

Oatmeal Chocolate Chip Cookie Dough Peanut Butter Brownies 2 With 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 & Brooke See? 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 1 Start 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 2 Spread into a greased and lined 9×9 baking dish and bake 25-25 minutes. Set aside to cool.

peanut butter layer For the peanut butter layer, stir together some peanut butter with vanilla, powdered sugar and milk.

peanut butter layer 2 You should get a semi-sticky concoction. Spread this over your brownies.

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

cookie dough 2 Add in your chocolate and oats…

brownies finished and top your brownies with it. And because it’s Father’s Day, add on some chopped M&M’s in boy-ish colors.

Oatmeal Chocolate Chip Cookie Dough Peanut Butter Brownies Drizzle with a little melted white chocolate mixture {in the recipe} and voila! Your bars are finito!

Enjoy friends! :) Happy Father’s Day!

1/3 cup melted butter

peanut butter layer:
1/2 cup creamy or chunky peanut butter
1 cup powdered sugar
2 tablespoons milk
1/2 teaspoon vanilla

2 2/3 tablespoons softened butter {remaining butter from the brownies}
1 tablespoon powdered sugar
1 tablespoon brown sugar
1/4 cup granulated sugar
3/4 teaspoon vanilla
1 tablespoon milk
1/2 cup all purpose flour
pinch of salt
2 tablespoons mini chocolate chips
2 tablespoons rolled oats {optional}

1 cup chopped peanut M&M's

for the drizzle-
1/4 cup white chocolate chips
2 tablespoons coconut oil or butter


Preheat oven to 350 degrees. Line 9x9 glass dish with foil and spray with non stick cooking spray. Set aside.

In large bowl, stir brownie mix, eggs and melted butter together until combined. Pour into prepared dish and smooth the top. Bake 25-35 minutes or until set and toothpick comes out clean after being inserted. {A few moist crumbs are fine.} Set aside to cool

For the peanut butter layer, mix all ingredients together in a small bowl until combined. Spread over the top of the brownies and press down lightly so it sticks.

For the cookie dough layer, cream butter and sugars together until light and fluffy. Stir in vanilla and milk. Stir in dry ingredients, then chocolate chips and oats. Spread cookie dough by the teaspoonful over the peanut butter layer and press down to flatten the top. Sprinkle with chopped M&M's.

In a small bowl, microwave white chocolate and coconut oil until smooth and completely melted. Drizzle overtop of the bars. Refrigerate 5-10 minutes or until the white chocolate hardens. Cut into 12 pieces and serve.

    • Lisa — June 21st, 2012 @ 4:31 pm

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


      • Lauren — June 21st, 2012 @ 5:54 pm

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

    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.
