These are my most well-liked bars. I typically create around 500 of these at birthday celebrations.

Directions:

Make Marshmallow Mix: Mix marshmallows and melted butter in a bowl that can be used in the microwave. Heat in the microwave for 1-2 minutes, stirring until it is smooth.
Melt white chocolate: Put white chocolate chips in a bowl that can go in the microwave. Heat for 30 seconds at a time, stirring until it is smooth.
Mix the ingredients together. Pour melted white chocolate on top of the marshmallow mixture. Mix until everything is well blended. Mix in pieces of gumdrops.

Bar forms: Put the mixture into a baking dish lined with parchment paper. Press down evenly.
Cool down and slice: Put in the refrigerator for 1-2 hours. Cut into bars and eat!
