Preheat oven to 350 degrees F. Line three baking sheets with parchment paper, set aside.
In a mixing bowl, combine butter, both sugars, vanilla and eggs one at a time.
Add dry ingredients until combined.
Drop 1 TBS portions of dough onto your prepared baking sheets. It’s important to make sure they’re all the same size and shape to make it easier to make the sandwiches.
Bake at 350°F for 10-12 minutes, or until they are golden brown.
Remove cookies from the oven. After a few minutes, gently separate & create space between the cookies if they baked together.
Let your cookies cool on the pan for 10-15 minutes.
When your cookies are mostly cooled, move onto a wire rack to cool completely.
While cookies are baking, make filling:
Beat together ½ cup butter and powdered sugar slowly until combined.
Add vanilla and whipping cream, beat until combined.
After cookies have cooled spread spoonful of filling between two cookies, putting the bottom sides together. Pop them into the freezer for a few minutes and enjoy!
