If you love Oreo cookies, then you're going to love this Oreo buttercream frosting. It's perfect spread over layer cakes or cupcakes, and it's easy to make too!
Add your cookies to a food processor or a large gallon sized baggie.
Pulse or mash into fine crumbs. The smaller the better, especially if you plan on using a piping tip as large cookie pieces can clog the tips. Set aside.
In a large mixing bowl, add the butter and powdered sugar.
Mix well with an electric mixer until the mixture is creamy and light.
Add in the vanilla.
Mix again to combine.
Add in your cookie crumbs.
Mix well to combine. The frosting will be thick.
Add in the milk, one tablespoon at a time, mixing after each until your desired consistency.
The cookie crumbs will soften as the frosting ages.
If needed, place the cookies n cream frosting into the fridge to chill until easy to use.
Spread or pipe frosting over cooled cakes, cupcakes, or cookies as desired.
Enjoy!
