   To make large cookies, use a large cookie scoop (about 3 tablespoons) to drop dough onto prepared cookie sheets. Bake in preheated oven for 13-15 minutes or until golden brown. To make small cookies, use a medium cookie scoop (about 1.5 tablespoons) of dough per cookie and bake for 10-12 minutes.

   Allow cookies to sit on cookie sheets for about 5 minutes before removing them to a wire rack to cool completely. Once cookies have cooled completely, prepare the cream filling.

Prepare the Cream Filling:

1. 6

   In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl with an electric hand mixer, beat butter on medium-high speed for about 5 minutes. This process will lighten the color of the butter and ensure you buttercream in extra fluffy.

2. 7

   Turn the speed down to low and gradually add in the powdered sugar. Continue mixing on low speed until the powdered sugar is completely incorporated. Add in vanilla extract and milk and mix until combined.

3. 8

   Turn mixer back up to medium-high speed and beat the mixture for an additional 3-5 minutes. If needed, add in a little more milk or half-and-half 1 teaspoon at a time until you reach the consistency you desire.

4. 9

   To assemble the cookies, pipe or spread the cream filling on the flat side of half of the cookies and put the remaining cookies on top.
