Preheat oven to 350 degrees F. Grease a mini muffin pan.
With an electric mixer, beat the butter, brown sugar, and granulated sugar until smooth and creamy, 2-3 minutes. Mix in the egg, then the vanilla. Add the flour, baking soda, and salt and mix until combined. Add the mini chocolate chips.
Fill mini muffin pan cups half full. Bake until edges are golden but center is still soft, about 12-14 minutes. Let cool in the pan about 5 minutes, then carefully transfer to a wire rack to cool completely. Repeat with remaining dough.
Make the frosting:
With an electric mixer, beat the butter and brown sugar until smooth and creamy, 2-3 minutes. Mix in vanilla. Mix in flour and salt. Add 1/4 cup heavy whipping cream and beat until smooth. If frosting is still too thick, add more cream 1 tablespoon at a time until desired consistency is reached. Stir in mini chocolate chips.
Top cookie cups with the frosting and sprinkle additional mini chocolate chips on top, if desired.
Notes
NOTE:
If you are concerned about consuming raw flour, you can toast it first before adding it to the frosting. Cook in a skillet over medium heat, whisking constantly, for about 6-8 minutes until lightly toasted. Let cool before using.
