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. Brownies, oatmeal chocolate chip cookie dough, peanut butter, and 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!

Brownies

Main Ingredients Needed

I know this list seems long and intimidating but don’t worry, I take you layer by layer and break these Cookie Dough Brownies down for you. Here’s what you’ll need:

For the Brownies

  • Brownie Mix – I used the Pillsbury brand but feel free to use another brand. Or make homemade brownies!
  • Eggs + Butter – these are the mix-ins that make the brownie mix moist and fudgy.

For the Peanut Butter Layer

  • Peanut Butter – so good! Feel free to replace it with almond butter, cookie butter, or Nutella!
  • Powdered Sugar – to sweeten and thicken the mixture.
  • Milk – to thin out the mixture a little bit.
  • Vanilla – to add flavor.

For the Cookie Dough

  • Butter – for flavor and moisture.
  • Powdered Sugar – to thicken and sweeten the dough without adding too much graininess.
  • Sugar + Brown Sugar – to sweeten some more!
  • Vanilla – for flavor.
  • Milk – to thin the dough out a little without using raw eggs!
  • Flour – if you are worried about bacteria, bake the raw flour before mixing it in.
  • Salt – to balance the sweet.
  • Mini Chocolate Chips + M&M’s – some yummy chocolatey mix-ins!
  • Rolled Oats – these are optional but we loved the added texture!

For the Drizzle

  • White Chocolate – you could also use another type of chocolate here, but I kept it light with white chocolate.
  • Coconut Oil – this is to thin out the melted chocolate so it can be drizzled on.

For full details on how to make these Cookie Dough Brownies, see the recipe card down below 🙂

Brownies

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.

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

Peanut Butter

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

You should get a semi-sticky concoction. Spread this over your brownies.

Cookie Dough

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

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

White Chocolate Drizzle

Drizzle with a little melted white chocolate mixture {in the recipe} and voila! Your bars are finished!

Cut and serve.

    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.
