Preheat the oven to 350°F (175°C).

In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

In a separate bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Scoop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper.

Bake for 10-12 minutes or until the edges are lightly golden.

Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

In a mixing bowl, whip the chilled heavy cream until soft peaks form.

Gradually add the powdered sugar and vanilla extract, continuing to whip until stiff peaks form.

Divide the frosting into separate bowls and add food coloring to each to create different colors.

Spread or pipe the colored cream frosting onto the cooled cookies.

Sprinkle with rainbow sprinkles and edible glitter for a magical finish.
