Ingredients
  

  • 1 box brownie mix plus ingredients listed on box
  • 1 box-5.9 oz. instant chocolate pudding mix family size
  • 3 cups milk
  • 1 8 oz. Cool Whip thawed
  • 12 Oreos crushed

Instructions
 

  • Prepare your boxed brownie mix according to the package instructions, then spread into a 9x13 pan and bake as directed. Let cool completely.
  • Meanwhile, prepare your pudding mix according to the directions on the box.
  • Add half of the Cool Whip until smooth and fluffy. (Optional: Save a couple of teaspoons of the chocolate pudding for the chocolate whipped topping if desired, so it's extra chocolatey)
  • Add half of the Cool Whip until smooth and fluffy. (Optional: Save a couple of teaspoons of the chocolate pudding for the chocolate whipped topping if desired, so it's extra chocolatey)
  • Once the pan of brownies has cooled, spread the chocolate mousse evenly over the top and chill in the fridge for 20 minutes.
  •  Add the extra pudding you set aside to the remaining Cool Whip to make a lighter chocolate whipped topping, and then sprinkle with crushed Oreos.
  • Chill 2-4 hours in the fridge before serving.

Notes

Variations:

  • You can change this dessert up by using cookies & cream pudding, then mix the crushed Oreos into the layers.
  • Add peanut butter to the brownie batter before baking, then add chopped peanut butter cups on top instead of the Oreos.
  • Try drizzling caramel sauce over the brownie layer before adding the mousse.

Helpful Tips:

  • Make sure the brownies cool completely before putting on your mousse, as it will melt.
  • Chill the mousse layer for 15-20 minutes before adding your chocolate Cool Whip topping.
  • When spreading your top Cool Whip layer, go slow to spread evenly. 
  • Adding the extra pudding to the top layer of Cool Whip is optional. We do it to make it extra chocolatey, but you can just omit that step if you want and use the regular Cool Whip on top.

Storage:

  • Store your bars in an airtight container for up to 3 days. You can also freeze it for up to 1 month. Thaw overnight in the fridge before serving. (Keep in mind that the mousse will be firmer after freezing but still delicious.)
