This is the easiest Dairy Queen copycat ice cream cake you will find but tastes exactly like a cookie dough blizzard ice cream cake! Using 2 kinds of store-bought ice cream, store-bought edible cookie dough, an easy 2 ingredient Oreo cookie crust in the middle and topped with store-bought whipped frosting or homemade frosting!
In a 10 inch springform pan, take ½ the vanilla ice cream and arrange it in an outer circle around the edge of the pan. Smooth it with a spatula.
Add ½ the chocolate ice cream in the middle. Put it in the freezer.
Chop up ½ the cookie dough (about 12 pieces) into small pieces and put the remainder back in the fridge.
Mix the remaining vanilla ice cream with the chopped cookie dough and put in the freezer.
Mix ½ cup butter (melted) with the Oreo cookies crumbs and mix until it clings together. Remove the cake from the freezer and add the cookie crumb mixture to the middle area (on top of the chocolate ice cream).
Then add the vanilla ice cream/cookie dough mixture into the middle, on top of the Oreo baking crumb mixture.
Then add the remaining chocolate ice cream, over the entire cake, smoothing it to cover everything. Return to freezer for at least 15 minutes.
Remove from pan.
Frost with your favorite store-bought or homemade frosting (see my recommendations in post.)
Using either store-bought or homemade chocolate chip cookie dough, shape cookie dough into small cookies and chop the rest.
Break up remaining pieces of cookie dough and sprinkle chunks of cookie dough into the middle of the cake. Place on cake as shown. Sprinkle grated chocolate.
