Preheat oven to 350 degrees and line two cookie sheets with parchment paper or a silicone baking mat
Using a standing mixer, beat the butter, powdered sugar, vanilla, and heavy whipping cream until combined
Gradually beat in the flour and salt until a dough forms
Using a small cookie scoop, scoop out some dough and roll it into a ball
Roll the cookie dough into the easter sprinkles and place it onto the cookie sheet
Make an indent into the cookie dough ball using your thumb or the back of a spoon
Bake in the oven for 7-10 minutes or until lightly golden on the bottom
Allow cooling while you melt the candy melts
Pour at least 1 c of the candy melts into their own piping bags and place into the microwave for 45 seconds until melted
Cut the tip off the piping bag and fill the cavity of the cookie with the melted candy melts
Allow hardening before enjoying!
