Instructions:

Melt white chocolate chips and sweetened condensed milk in a saucepan over low heat, stirring constantly until smooth.
Remove from heat and stir in cotton candy flavoring.
Divide the fudge mixture into two bowls. Add pink food coloring to one bowl and blue to the other.
Pour each colored fudge into a parchment-lined dish, creating swirls or layers.
Refrigerate for at least 2 hours until set.
Cut into squares and decorate with sprinkles.
