• Take the Cool Whip out of the freezer and let thaw in the fridge while you prep the rest of the ingredients. You want it to be partially thawed when you use it to "frost" the bars.

Oreo Bars

• Line an 8"x8" baking dish with aluminum foil. Set aside.
• In a small saucepan (or heatproof bowl in 15 second increments), melt butter over low heat.
  6 tablespoons unsalted butter
• In a food processor or blender, pulse 6 whole Oreos to a fine crumb.
  14 Oreos
• In a medium mixing bowl, combine melted butter, pulsed Oreos, and the packet of crust mix from the Jell-O mix box.
  1 box Jell-O Oreo No Bake Dessert mix
• Press Oreo crumb mixture into the prepared foil-lined baking pan in an even layer.
• In a large mixing bowl with an electric hand mixer (or in a stand mixer), beat to combine milk with the packet of filling mix from the Jell-O mix box. Start on low speed for 30 seconds, then increase speed to medium for another 3 minutes.

  The mixture will be thick and creamy.
  1 1/3 cup milk
• Roughly chop 8 whole Oreos and set aside 1/2 cup for garnish. Add the rest to the milk mixture, along with the final packet of Oreo pieces from the Jell-O mix box. Use a mixing spoon or spatula to stir and evenly combine.
• Pour the filling on top of the crust and use a spatula to evenly distribute the filling.

Cool Whip Frosting

• In a large bowl using a hand mixer, beat Cool Whip on low for 1 minute.
  8 ounces Cool Whip
• Add vanilla extract and cream of tartar and beat again on medium low for a couple minutes until thick, creamy and combined.

  Taste test, and if you'd prefer it to taste sweeter you can add powdered sugar 1 tablespoon at a time, beating after each addition until desired sweetness is reached.
  1 teaspoon clear vanilla extract, 1/4 teaspoon cream of tartar, powdered sugar
• Transfer frosting to a piping bag fitted with a piping tip and decorate the bars however you'd like. You can also just use an icing spatula to spread the frosting across the top. Top with reserved Oreo pieces and/or whole Oreos.

  Slice into 9 squares, serve and enjoy!
