Directions for Brookie Mousse Icebox Cake:

First, lightly spray the bottom of a 9” springform pan and line the inside of the pan with a 6” acetate collar

Next, pour the milk into a shallow bowl and dip both sides of an Oreo in the milk.

Then, arrange 19 Oreos dipped in milk in the bottom of the Springform pan.

Brownie Layer

Next make the brownie layer by chopping enough brownie bites to equal I cup.

Now, using a spatula, scoop out the Cool Whip into a large bowl.  Fold in the DRY instant chocolate pudding and cocoa powder until thoroughly combined.

Next, fold in the chopped brownies.

Now spread the brownie mousse on top of the Oreos in the springform pan, making sure you get the mousse in between the Oreos.

Then create another layer of Oreo cookies dipped in milk on top of the brownie mousse layer.

Oreo Layer

Next make the Oreo mousse layer by chopping up 1 cup of Oreo Cookies.

Now, using a spatula, scoop out the Cool Whip into a large bowl.  Fold in the DRY instant Oreo pudding and powdered sugar until thoroughly combined.

Next, fold in the chopped Oreos

Now spread the Oreos mousse on top of the Oreo cookie layer in the springform pan, making sure you get the mousse in between the Oreo cookies.

Then create a final layer of Oreo cookies dipped in milk on top of the Oreo mousse layer.

Chocolate Chip Cookie Layer

Now make the Chocolate Chip Cookie Layer by chopping 1 cup (about 4 or 5 cookies) of the soft Pepperidge Farms Montauk Chocolate Chunk cookies.

Now, using a spatula, scoop out the Cool Whip into a large bowl.  Fold in the DRY instant vanilla pudding, vanilla extract and brown sugar until thoroughly combined.

Next, fold in the chopped chocolate chip Montauk cookies.

Now spread the chocolate chip cookie mousse on top of the Oreos in the springform pan, making sure you get the mousse in between the Oreos.

Now refrigerate cake for 8 hours or overnight.

To make the ganache place the chocolate chips in a large mixing bowl.

Next in a small pan, heat the heavy cream over medium heat until you see just a few bubble, (very hot but not boiling)

Then immediately pour hot cream over the chocolate chips and let sit for a few minutes.

Now stir the cream and chocolate together until completely melted and smooth. 

Set aside until cool to the touch. Start with a little at a time and spread the ganache on top of the cake (you will have leftovers)

Next, decorate by piping Cool Whip with a 1M tip and alternating Oreo and Chips Ahoy cookies and brownies around the top of the cake.

Finally, top each brownie with Cool Whip and a cherry

Now you have a beautiful 3 Layer Brookie Mousse Icebox Cake! A real show-stopper and SUPER EASY to make! No baking involved and you can make it the day before. Great for company or a special occasion or holiday!
