Preheat your oven to 350°F (175°C).
Cream together the softened butter, granulated sugar, and brown sugar in a large mixing bowl.
Add the eggs one at a time, followed by the vanilla extract, mixing well after each addition.
In a separate bowl, combine the all-purpose flour, baking soda, and salt, mixing thoroughly.
Gradually add the dry mixture to the wet ingredients, mixing until just combined.
Scoop the dough into a greased muffin tin, filling each cup about two-thirds full.
Bake in the preheated oven for 12-15 minutes until edges are golden and centers look set.
Let the cookie cups cool in the pan for 5 minutes, then carefully remove and cool completely on a wire rack.
Once cooled, fill each cookie cup with whipped cream and top with assorted candies.
