How Do You Store Confetti Bars?

You can store these bars at room temperature, however I love to eat them cool from the refrigerator! It’s like eating a cool ice cream bar. They will last in your fridge for about a week if not longer.

You can also freeze these delicious morsels! They are perfect to keep in the freezer for times when unexpected guests pop in, or you need a quick after school snack for the kids.

They are also delicious with an afternoon coffee or tea!

I hope you love this easy and classic treat! I remember my mom making these for us or for community events, and they were always the first to go! Enjoy!
