Browned butter filling
In a small saucepan brown the butter on medium to low heat. Once the butter has melted the butter will start crackling. Continue to keep on eye on the butter and once you start smelling the nuttiness and see the butter turn amber keep a close eye on it. Once the butter turns into a darker amber almost caramel color take it off the stove and allow it to cool.
Once the butter has cooled cream the butter until fluffy and then add in the powdered sugar, heavy cream and vanilla until creamy.
Assembly:
Match up the cookies according to the size and then pipe just enough of the filling leaving some room on the edges to allow the filling to spread when you sandwich the cookies together.
