Homemade Oreo Brookies

A delicious, decadent mix of smooth chocolate chip cookie dough, satisfying Oreo cookies, and rich brownie mix. All combined to make the most amazing treat you've ever had!

Equipment

  • 1 set measuring spoons
  • 1 Large Bowl
  • 1 9x13 pan
  • 1 bowl scraper
  • 1 hand mixer
  • 1 can of cooking spray

Ingredients

Homemade Brownie Layer

  • ½ cup butter optional use of box mix
  • 1 cup + 2 tbsp granulated sugar
  • 1 egg
  • ½ tbsp vanilla extract
  • ¾ cup flour
  • ½ cup + 2 tbsp dark cocoa powder
  • ½ tsp baking powder
  • ½ tsp salt
  • 1 cup dark chocolate chips

Oreo Layer

  • 1 pack original Oreos

Cookie Dough Layer

  • 2 16oz packages pre-made cookie dough optional use of homemade cookie dough

Instructions

  • Preheat the oven to 350 degrees.
  • Grease a 9x13 pan or line it with parchment paper. (Tip: I prefer glass and greasing the pan for these so I can see the base better.)
  • Prepare/open your cookie dough and spread evenly into the bottom of your pan.
  • Place a single layer of Oreos overtop your cookie dough.
  • Prepare your brownie mix (homemade or as directed) and spread evenly over top your Oreos. It may be helpful to spoon dollops of mix all over and then use a rubber spatula (or your hands if it’s really thick) to spread into an even layer.
  • Bake at 350 for about 40 minutes. A toothpick should come out mostly clean with a few moist crumbs on it. Poke another spot to check if your first poke only brought up chocolate chip! If you can see the base, it’s helpful to see the cookies turning golden.
  • Cool completely and remove. Either flip out (quickly!) onto a cutting board or use the edges of the parchment to pull up gently.
  • Once cooled (don’t skip this!!), cut brownies to desired size. I tend to cut mine a little smaller than I normally would simply because they are so thick and rich.
  • Store in an airtight container up to a week, assuming they last that long!

Notes

Homemade Brownie Mix Recipe
  1. Preheat oven to 350 degrees.
  2. Grease an 8x8 pan and set aside.
  3. In a medium saucepan, melt the butter over medium heat.
  4. Add the sugar to the saucepan and cook for two minutes, stirring so it doesn’t burn.
  5. Remove from heat and let cool several minutes.
  6. Add your egg and vanilla. Stir until combined.
  7. In a separate bowl, mix together your dry ingredients - flour, dark cocoa powder, baking
    powder, salt.
  8. Combine your wet ingredients with your dry, mixing until just combined.
  9. Add chocolate chips, mixing again until just combined.
  10. Spread into your pan and bake for 25-30 minutes. A toothpick should come out with damp crumbs. You may need to test a couple areas due to the chocolate chips. You don’t want to overcook these! Another check is the edge – it should be firm and just starting to pull away from the edge of the pan.
  11. Let cool for an hour or so before cutting.
