makes around 36 cookies/18 whoopie pies

Ingredients
113gm butter, at room temperature
225gm sugar ( i used 175gm )

Beat the butter and cream cheese till smooth , add in icing sugar bit by bit until you reach the desired consistency and taste. 

Method for whoopie pies: 
1. In a large bowl, beat butter with sugar until light and fluffy , beat in eggs and vanilla.

2. In a separate bowl, whisk together flour, cocoa powder, baking powder and salt. Stir into butter mixture alternately with buttermilk, making 3 additions of flour and 2 additions of buttermilk.

3. You can drop by tablespoons of batter onto the parchment paper, leaving 3 inches apart and bake in a preheated oven at 180C until the top is slightly crack and spring back when lightly touched, about 12-14 minutes. ( i used a piping bag to pipe the batter onto the parchment paper, i piped them round about diameter 3.5cm each ) Let them cool in a wiring rack.

4.To assemble, take a dollop of filling and sandwich between 2 cookies.
