I Am Giving a Gourmet Chocolate Party For My Little Girl. How Do I Make Melted Chocolate Chips Taste Better?

Last year i gave my niece the exact same party and i had things like, chocolate covered marshmallows, rice crispy treats, licorice, oreo’s, pretzels etc. But, when i drizzled the chocolate it didn’t taste sweet enough. I am looking for the gourmet milk chocolate taste but don’t have all that money to spend. I was told that there was a way to make the chocolate sweeter but don’t know the way. Please, need help soon. I will appreciate your suggestions!!!!!!!!
