HOW TO PREPARE FUNFETTI COOKIE BARS

FAQ

Put a clean toothpick into the bars and pull it out. If the toothpick is clean, they’re ready to be pulled from the oven.

You most likely did not allow the cookie dessert to cool completely. The frosting will melt right off the top if the dessert is still hot or warm.
