Using a food processor or blender, pulse the Oreo cookies until they turn into a fine powder. Set aside.
In a large mixing bowl, beat the softened butter until it's smooth and creamy, about 2-3 minutes.
Gradually incorporate the powdered sugar, half a cup at a time, beating well after each addition.
Add the vanilla extract and a pinch of salt to the mixture, blending until combined.
Pour in the heavy cream, one tablespoon at a time, until you achieve a smooth, spreadable consistency.
Gently stir in the crushed Oreo cookies until they're evenly distributed throughout the frosting.
Your frosting is now ready to be spread or piped onto your favorite desserts. Enjoy!
