To make the chocolate buttercream
Using a hand mixer or a stand mixer fitted with the paddle attachment, cream the butter until fluffy.
Add cocoa powder, heavy cream, vanilla and salt. Mix until combined.
Add powdered sugar, 1 cup at a time, mixing well after each addition, until you have reached desired frosting consistency (usually 4-5 cups total).
Assembly
To assemble the cookie cake, place the bottom later on your serving plate or cake plate.
Add the chocolate frosting to a piping bag with a star tip. Pipe out frosting rosettes around the edge of the bottom and center cookie. Then fill in the rest with frosting in an even layer. Gently stack the cookie cake layers on top of each other.
Option to top with sprinkles, more chocolate chips, or candles for a birthday party!
